Why don't men understand women?
by Isabel Torres in Science in the clouds
Men might have found themselves an excuse not to listen to women. New research suggests that men have twice more difficulty reading emotions in women than in men. This may not sound surprising, but evidence that men have trouble understanding women is, at best, scarce.Being able to guess someone else’s thoughts, feelings and intentions is an instinctive social skill that develops in early childhood. We might take it for granted, but people who struggle or are unable to read other people, like ........ Read more »

Epilepsy Service Organization in Countries with Limited Resources
by Vivek Misra in Beautiful Mind
tumblr: bellapaige88On average, 9.5/1000 population has epilepsy in Low and Middle Income Countries (LAMIC). A research which has resulted in the global campaign against epilepsy has shown, the gap between treatment need and the treatment provision worldwide is approximately 70% [1]. This large ‘treatment gap’, i.e., lack of appropriate treatment for a large number of patients with epilepsy, due to a number of causes including inability to identify cases, inability to deliver adequate treatm........

Epidemiology of Childhood Brain Disorders: ADHD and Autism
by William Yates, M.D. in Brain Posts
The U.S. Centers for Disease Control has published a comprehensive summary of the epidemiology of childhood brain disorders in the most recent Morbidity and Mortality Weekly Report.This report produced some sensationalized headlines that up to 20% of children suffer from a mental disorder. However, I was more interested in looking at the prevalence estimates for some of the individual disorders from the report.The report collates data collected from a variety of surveys and data sets inclu........

Fantastic Distortions of Perception
by Neuroskeptic in Neuroskeptic_Discover
A new paper in the journal European Neurology reports on a remarkable case of perceptual distortion that’ll please any connoisseur of neurogothic: A 48-year-old woman woke up one morning without knowing where she was.

Homeostatic platsicity in a thorny situation
by TheCellularScale in The Cellular Scale
Synapses, the connections between neurons can strengthen and weaken depending on the specific activity at that synapse. This is called synaptic plasticity, and we've talked about it a lot on this blog (here, here, here and here).the strengthening and weakening of synaptic connections corresponds to the spine growing or shrinking (Matsuzaki 2007)However, there is another kind of plasticity that can occur at synapses. This is called homeostatic plasticity. And instead of the synapse strengthening ........ Read more »

Good News or Bad News - Skin cancer and Alzheimer’s disease
by Usman Paracha in SayPeople
Main Point:
Researchers have found that the people, who develop skin cancer, may have less chances of developing Alzheimer’s disease in the older ages.
Published in:
Neurology
Study Further:
Alzheimer’s disease is a degenerative disorder that affects the brain and causes dementia, especially late in life.
In this new study, researchers worked on 1,102 volunteers with an average age of 79. They were studied for about 3.7 years. In the beginning of the study, 109 peop........ Read more »

The effectiveness of placebo treatment for pain is related to personality traits

Ladies: why Ritalin may not always be helpful. (Hint: sex, genes and dem hormones)
by Shelly Fan in Neurorexia
Little note: Since this post, I’ve been mulling over why Ritalin/Adderall don’t affect cognitive performance of healthy volunteers. Several reasons come to mind. I wasn’t reading the “right” literature (ie studies with positive results – any suggestions?). Stimulants may only influence brain activation patterns, but not performance. In this case, we can only detect differences […]... Read more »

You are what you eat – wait, no, you eat what you are. Wait, that’s not it…

The public will never tire of the nature versus nurture debate but here’s a hint: the answer in biology is always both. But if you’ve ever known any twins, you know they can have quite different personalities which, you would think, are attributable to differences in nurture of one sort or another. To understand this better, some scientists […]... Read more »

Bingeing and Purging: Keeping the “Positives” and Eliminating The Negatives?
by Liz in Science of Eating Disorders
I have been fascinated and perplexed by reports of the seemingly invigorating and anxiety reducing effects of bingeing and purging (purging by self-induced vomiting). Personally, I cringe at the idea of self-induced vomiting and have always wanted to avoid vomiting at all costs, including during food poisoning. The insight from recent blog entries and the subsequent comments has made an impact on me. I see that the motivation to engage in bingeing/purging (b/p-ing) behavior ........ Read more »

Experience leads to the growth of new brain cells
by Perikis Livas in Tracing Knowledge
How do organisms evolve into individuals that are distinguished from others by their own personal brain structure and behaviour? Scientists in Dresden, Berlin, Münster, and Saarbrücken have now taken a decisive step towards clarifying this question. Using mice as an animal model, they were able to show that individual experiences influence the development of new neurons, leading to measurable changes in the brain. The results of this study are published in Science on May 10th. The DFG-........ Read more »

The Inadvertent Psychological Experiment
by TheCellularScale in The Cellular Scale
Escape from Camp 14 is deeply disturbing, and I highly recommend it. Escape from Camp 14 by Blaine HardenEscape from Camp 14 is a chilling tale of Shin Dong-hyuk's escape from a North Korean prison camp. What is so interesting about Shin Dong-hyuk's story as written by Blaine Harden is that he was born inside this North Korean prison camp. Apparently they allow breeding between prisoners as a reward for 'good behavior.'Escape from Camp 14 reveals the obscene violations of human rights that occur........ Read more »

Visualizing the Connectome

Last year, I blogged about a new and very pretty way of displaying the data about the human ‘connectome’ – the wiring between different parts of the brain. But there are many beautiful ways of visualizing the brain’s connections, as neuroscientists Daniel Margulies and colleagues of Leipzig discuss in a colourful paper showcasing these techniques.
