#repost ・・・ The brain is the best protected organ in the body. The blood-brain barrier (BBB) is composed of closely-spaced cells helps keep harmful substances from reaching the brain. The BBB is formed by endothelial cells of the vessel, astrocytes and pericytes embedded in a membrane called basement membrane. The BBB restricts the diffusion of bacteria, virus and toxins while allowing the diffusion of nutriments. Many important medications, including some anti-cancer drugs, are unable to cross the BBB, presenting challenges for researchers and doctors treating brain diseases.

In today's update Enver shares about his favourite neuroanatomy structure the Posterior Inferior Cerebellar Artery (PICA). Anatomy Challenge Season 3's very own chairman elaborates his choice quoting that the structure PICA sounds like Pikachu. But is Enver really the pokemon enthusiast he seems to be? Find out more from him by signing up for Anatomy Challenge, coming to your JC/Polytechnic soon! (And oh, if you are up for a test of your anatomy skills)
[Le cerveau immature de l’enfant]
L’existence des 3 cerveaux :
👉 Le cerveau archaïque ou reptilien (tronc cérébral et cervelet) - gère des fonctions primaires
- déclenche des comportements liés à l’instinct de survie tels que l’attaque ou la fuite
👉Le cerveau émotionnel ou « système limbique » (amygdale, hippocampe, hypothalamus, cortex cingulaire, cortex préfrontal, insula, noyau accumbens, septum, ganglins de base)
- fait ressentir toute la gamme des émotions
👉 Le néocortex ou « cerveau supérieur »
- gère les fonctions cognitives dites supérieures comme le langage, la conscience…
- Le néocortex est en formation durant les premières années de vie. Il ne peut donc exercer de contrôle sur les deux autres cerveaux.
- La maturation du cerveau a lieu jusque vers 25 ans.
- A 2 ans les synapses sont deux fois plus denses que chez l’adulte.
- Physiologiquement, l’enfant n’a pas la capacité de gérer la totalité des situations ni d'accompagner des émotions auxquelles il est confronté. - Les structures et réseaux du cerveau de l’enfant font qu’il ne peut pas réagir comme un adulte. Ce n’est pas un problème de volonté mais bien de capacité.
- Les premières années de vie sont celles pendant lesquelles le cerveau est le plus vulnérable.

If you keep falling for the same shit over and over, then maybe you ARE man-stupid and you need an intervention -- a real EXorcism. It drives me crazy that some women are so brilliant at school, at work, and at life, but so silly when it comes to men! 😡 You're worth so much more, girl!
If that is you, here's what you can do to help yourself:
Call in your most sensible and objective girlfriends, open a bottle of wine, and instruct them to bombard you with truth bombs for an entire evening. Minimum 3 hours. Nothing is off limits! Commit to seeing things from an outsider's point of view. If everyone else can see it, eventually you will too! The point is to WAKE YOURSELF UP from your oxytocin-induced love stupor. (It's a real thing!) 🙄🤯
YOU WILL LEARN A LOT from the session. It will be painful but it will be SO liberating. You just have to be brave and accept the truth.
Don't say crap like "... it doesn't seem like it but i know deep down in his heart he loves me."
"...but you just don't understand him that's why you think he's bad."
That's rubbish. Don't make excuses. A person who cares about you won't be putting you in turmoil. And that's a FACT.
[Oh, men can do this too! But you need to invite women to your EXorcism, not men.]
Need help? Let me know. ❤
In this new book by Dr. Franz Schelling unravels the mysteries of #CCSVI and #MS. “....takes a closer look into the earliest days of MS research sees that MS has not always been just a mysterious entity. .
That it had unmistakable features of its own. In pursuing the given strands of evidence up to the most recent advances in MR imaging, a well defined MS agent begins to emerge: 👉 The #retropulsive#venosome. Those who elucidate the nature and activities of these potentially ruinous venous bodies are expected to solve the basic problems of not only CCSVI and MS "

Sensorimotor communication for humans and robots: improving interactive skills by sending coordination signals
IEEE Transactions on Cognitive and Developmental Systems (TCDS). Vol 10 (4). pp. 903-917. doi:10.1109/TCDS.2017.2756107 December 2018
"..O nome dela é Jennifer!..." Ah!!! Pq essas músicas "chiclete" não me saem da cabeça?! Esse fenômeno irritante (para alguns) , que faz com que fiquemos repetindo mentalmente músicas, é chamado coloquialmente de earworm (“minhoca de ouvido”), termo criado pelo professor James Kellaris, da Universidade de Cincinnati. .
Quando estamos desocupados ou distraídos, basta pensar rapidamente numa música para o fenômeno acontecer. O que se forma, então, é algo parecido com uma coceira cerebral - O jeito de amenizar o incômodo é repetir mentalmente a música ad infinitum. .
Para descobrir isso, pesquisadores da Universidade Dartmouth, nos EUA, colocaram voluntários para ouvir música. Sem aviso, a música parava. Quando a melodia era conhecida do ouvinte, o córtex auditivo continuava trabalhando, relembrando a melodia. Quando a música era desconhecida, a mente do sujeito ficava vazia. Para ocupar esse espaço, o cérebro começava a repetir o que tinha acabado de ouvir. Estranhamente, mulheres são mais suscetíveis ao fenômeno – só não se sabe ainda por quê.
O professor Kellaris diz que qualquer canção pode entrar em looping. “Mas músicas simples, repetitivas e com mudanças inesperadas de tons têm mais probabilidade de 'grudar' ”, diz. São aquelas formadas por refrões, frases marcantes ou oscilações na voz… .
Em outro estudo foram avaliadas, por meio de neuroimagem, as áreas sensoriais da audição e sentimentos e a espessura cortical dessas áreas definindo a probabilidade de as pessoas ficarem com as "minhocas na orelha"/"músicas chiclete" e a probabilidade de essas músicas as atrapalharem ou ajudarem no cotidiano. .
Jennifer é neurociência!
Lady Gaga também... Ivete Sangallo tambem... que outra música não sai da sua cabeça?
DIA 22 do DESAFIO MÚSICA E MENTE.
Eu quero tocar melhor em 2019.
Vamos continuar nossa conversa sobre o LOOP DO ESTUDO e seus elementos.
Uma das perguntas do Loop do estudo que você deve se fazer ao estudar é: QUANDO?
Você sabe QUANDO vai estudar?
Em qual momento do seu dia?
Você estuda sempre no mesmo horário do dia?
Você estuda todos os dias da semana?
Se a resposta for não, em quais dias você vai estudar?
Essas são algumas questões que devem estar bem definidas antes de pensarmos em um plano de estudo.
Arrumar um lugar na nossa agenda diária nem sempre é fácil. Por isso, é muito importante saber utilizar bem o tempo.
Nessa etapa do loop, trabalhamos a gestão do tempo, ou seja, como fazemos o uso do nosso tempo, ⏳ e a gestão da nossa energia, que são essenciais para termos um bom estudo.⚡
Muitas pessoas acham que ter tempo e querer estudar são suficientes para termos um estudo de sucesso, mas não é bem assim.
Neste vídeo, para os participantes do #desafioMusicaeMente eu falo 7 passos para cuidar melhor da sua energia, como beber água e movimentar-se e também ensino um exercício, simples e poderoso, o Conectando o carregador. 💆O COC é um exercício realizado em poucos minutos e que nos ajuda a recuperar a nossa energia ao longo do dia para continuarmos a realizar o que queremos.
Ele vai aquietar a sua mente, o que possibilita uma melhora na atenção, no foco e na concentração e ele também descansa os nossos olhos da leitura das partituras, que é um tipo de leitura que exige muito da nossa visão.
Adotar esses passos e fazer esse exercício, revigoram nossa energia, aumentando a nossa disposição para continuar nosso dia. 😉

Just finished reading this wonderful book about how to parent from a neuroscience/ brain science perspective. 10/10 would recommend as a must read to all parents, caregivers, teachers, and other adults who interact or work with children of all ages.
What I like about the book particularly:
🌟The way they write about all the new research and findings within neuroscience and about the brain so clearly and concisely. Its easy to read and understand even for someone with zero brain, neuroscience, or psychology background or knowledge.
🌟They not only talk about theories and research but also give practical strategies on how to implement in your everyday life each finding or theory they share.
🌟The layout of the book is really helpful - the theories and research sets up the logic behind the strategies in natural progression
🌟Really enjoyed the anecdotes and personal examples they have shared from their own life with their kids.
🌟At the end of the book, they also include ‘refrigerator sheets’ which summarise concisely everything so you don’t forget about all the cool things you have just learned and actually apply it all.
🌟And lastly, the book is relevant to parents of children of all ages. They even include how to apply each strategy at different ages and stages of a child’s life.
Emotions are Contagious. Spread carefully!
Both positive and negative emotions are contagious. We have a specific set of neurons in our brains called mirror neurons. Their entire job is to help us mimic those around us. Humans have managed to survive and evolve by working together in tribes for hundreds of thousands of years, because there is safety in numbers. But to be in a tribe we need to be accepted and to accept others, so we look for similarities. We subconsciously want to reinforce our sense of safety by seeking out what is familiar and that is what our mirror neurons do. This is what we call empathy. The challenge with these amazing neurons is that they are so effective in mirroring, they even take in the emotions of those around us, again so that we are fitting in because that is how our ancient brain is wired to keep us safe. So remember the next time that you are experiencing an emotion, good, bad or ugly, think about whether you might be infecting the people around you with your emotions. And remember the next time someone else is being intensely emotional, think about whether letting them infect you is good for your wellbeing. #emotionalintelligence#emotionalstress#wellbeing#keepitincheck#dontgetyourpantiesinabunch#empathy#selfawareness#emotionalselfcontrol#emotionalcontagion#tribalawareness#emotions_expert#loveyourtribe#dontownanyoneelsesstress#dontgetsuckedin
When faced with a point in your life where you wish to work towards change, the mind is never full of positive thoughts alone. We are often faced with doubt creating both a positive and negative narrative within our minds. For me, changing careers was accompanied by negative thoughts stemming from the fear of not having stability. But, the trust in my gut and dedication to making it work was the drive behind growth and positive change 🌱
Posso dizer que nesses três primeiros dias: já fui mais feliz, mais inspirada e mais segura da onde estou, do que nos anos anteriores. Obrigada por tudo! Eu amo vocês! Bora aproveitar ao máximo esse curso lindo.
Finished yet another project and presented my findings on microglial cells in Alzheimer’s disease.
Here are my favourite #microscopy images I took of brain sections of Alzheimer’s disease mouse model:
1) two types of microglia (green and red) around amyloid plaques (blue)
2) amyloid plaques labelled for filaments (red) and beta-sheet (blue)
3) neurons overexpressing amyloid precursor protein
4) plaques (red) and active microglia (green) in the hippocampus and cortex

What will you experience that makes you choose to be happy today?
Throwback to Indonesia where I had some of the biggest experiences of my life whilst being terribly Ill and still chose to experience. (Another post for that will be needed)

Thankful. For amazing attendings that give me enough room to learn while keeping the patient safe. And for an amazing senior resident that helped convince me to join our program as a medical student and who is going to make an amazing chief next year.
FROM WATER TO AIR
These are the magical moments of transition from water to air!We know how much you all LOVE these en-caul births (the process of when a baby is still in the amniotic sac as it emerges from the womb during a cesarean birth)!What's MEDspiring about this occurrence is that it can remind each of us that we ALL once did not need to breath air in order to survive!Thats RIGHT!When we were living inside the uterus of our mother, we received oxygen& nutrients from our mothers blood stream (an awesome super power pregnant women have: they breath & eat for two!) The reason each one of us has a belly button is because theumbilical cord we were once connected to was connected our mother's placenta inside the uterus (this placenta is what allowed for us to receive the oxygen & nutrients from momma's blood).First lesson: We were all made to break barriers!We each made a transition from water to AIR!Second Lesson: Adequate amniotic fluid volume is essential in preserving fetal life & is maintained by a balance of fetal fluid production (lung liquid& urine) & resorption (swallowing & intramembranous flow).When in the womb, the fetus must maintain a balance between swallowing amniotic fluid, having it flow through it's newly developing gastro-intestinal system & through the kidneys where it can urinate into the amniotic sac!This function assures proper maturation of the fetal CNS & organ systems (including the lungs).If something alters this cycle, such as an obstruction or agenesis of the fetal kidneys (resulting in an inability to excrete urine), then the amniotic fluid volume dramatically decreases (oligohydramnios).In other cases, fetal malformations (eg, esophageal/ duodenal atresia & anencephaly) can result in the inability to swallow amniotic fluid, causing an excess of fluid (polyhydramnios) is incredible to ponder how life is in constant geometric balance even before we take ourfirst breath on this planet!How cool is that?Happy Friday ladies & gentlemen.

Happy Monday you amazing people. I have a new feature alert for you! ✨
Okay, I basically want to post more science this year and make that science as much about day-to-day experiences as possible. So I thought I would do a 3-4 part blog series each month around a normal-turned-neuro theme. These posts will be released on a Thursday with the hashtag #NormalTurnedNeuro. Hopefully this will keep me on top of my writing too! 💻🧠
Drumroll please for January’s Theme 🥁🥁🥁
“The Brain, The Body and The Burn” 💪🏼
I love fitness, and Jan is the time everyone trials their fitness routines for the year. But how does exercise and healthy eating affect the brain? This 3 part series will explain the physiological effects of reduced calories and muscle growth, that rush you feel after doing a workout and exercise addition 🏃🏻♀️🏃🏾♂️
First post be happenin this Thurs so watch this space and tag any fitness friends who would brain-ne-fit from this info 🧠🏋🏻♀️ .
If you have any themes you want me to cover this year, lemme know! Kit is from my fave @gymsharkwomen#gymsharkwomen 💪🏼💪🏼💪🏼
Humans have been at the top of nature's food chain for a long time.
Why is that?
We aren't the physically strongest species on this Earth. A gorilla could smash our skulls into the ground without thinking twice about it.
We aren't the fastest species. A cheetah's leisurely sleep walk is faster than the fastest man in the world.
We aren't the most venomous species. I think an elephant would prefer our bite over a king cobra's any day of the week.
We aren't the most durable species. Cockroaches can survive through extreme amounts of radiation.
We don't have any interesting built-in biological defenses either. Porcupines have their spikes, and peacocks have their feathers.
Humans are fragile. The vast majority of animals in this world could kill us effortlessly given the opportunity to do so, yet we still stand as the most dominant species. What do we have that others don't?
The ONLY competitive edge we have is our intellect. Our ability to communicate, share information, learn from mistakes, make rational decisions, and increase our standard of living is exponentially better than that of any other species, and makes up for our lack of physicality. Knowledge is power. A snake will never create a more efficient life for itself. It will always hunt prey with its venom and return home when it's satisfied. It's the only thing the snake knows how to do, and it will never be able to start a business hiring other snakes to do the work for it.
Through our intellect, we are able to domesticate other species for our own selfish needs such as entertainment and food. We manipulate animals to do as we please by enticing them with their most primal biological need, food. That Shamu at SeaWorld is content with doing flips because it is rewarded with constant treats. The chicken in the slaughterhouse copes with the trauma by being fed until it can't eat anymore.
What happens when a new species that outperforms us physically AND intellectually is introduced into the ecosystem? They will domesticate us, exactly how we domesticate other animals.
