Brain is not fully mature until 30s and 40s

Brain is not fully mature until 30s and 40s
( -- New research from the UK shows the brain continues to develop after childhood and puberty, and is not fully developed until people are well into their 30s and 40s. The findings contradict current theories that the brain matures much earlier. Professor Sarah-Jayne Blakemore, a neuroscientist with the Institute of Cognitive Neuroscience at University College London, said until around a decade ago many scientists had "pretty much assumed that the human brain stopped developing in early childhood," but recent research has found that many regions of the brain continue to develop for a long time afterwards. The prefrontal cortex is the region at the front of the brain just behind the forehead, and is an area of the brain that undergoes the longest period of development. Prof. Blakemore said brain scans show the prefrontal cortex continues to change shape as people reach their 30s and up to their late 40s. Explore further: Study: Our brains compensate for aging

Neurogenesis Neurogenesis (birth of neurons) is the process by which neurons are generated from neural stem cells and progenitor cells. Most active during pre-natal development, neurogenesis is responsible for populating the growing brain with neurons. Recently neurogenesis was shown to continue in several small parts of the brain of mammals: the hippocampus and the subventricular zone. Women's exercise linked to lower cognitive skill - health - 07 January 2011 WOMEN who habitually take strenuous exercise might be at risk of damaging their cognitive function later in life. Strenuous exercise is known to reduce oestrogen levels in women and girls. This can delay the start of menstruation, and can lead to irregular periods in adult women. Low levels of oestrogen in premenopausal women have been linked to impaired mental function in later life. Mary Tierney at the University of Toronto, Canada, reasoned that strenuous exercise might therefore lead to impaired cognition in later life. She asked 90 healthy post-menopausal women to report their life-long exercise habits, and then tested their cognitive ability.

First Alzheimer’s Treatment to Fully Restore Memory Functionality As anyone who has seen what Alzheimer’s can do to a person will tell you, it’s not pretty, it’s not fun and it’s one of the most difficult diseases to deal with for both parties. It’s difficult to watch those you love grow older, but when they begin forgetting everything and everyone around them it can be just as damaging to those around them. What makes this disease such a problem is that there have been no significant advances in curing it or reversing its effects since the initial discovery in 1906. The scientists and researchers from the Queensland Brain Institute at the University of Queensland have been working diligently to discover something that would help, and it appears they may have now found a viable treatment.

The Human Connectome Project The Human Connectome Project Human Connectome The NIH Human Connectome Project is an ambitious effort to map the neural pathways that underlie human brain function. Religion May Cause Brain Atrophy Faith can open your mind but it can also cause your brain to shrink at a different rate, research suggests. Researchers at Duke University Medical Centre in the US claim to have discovered a correlation between religious practices and changes in the brains of older adults. The study, published in the open-access science journal, Public Library of Science ONE, asked 268 people aged 58 to 84 about their religious group, spiritual practices and life-changing religious experiences. Changes in the volume of their hippocampus, the region of the brain associated with learning and memory, were tracked using MRI scans, over two to eight years. Protestants who did not identify themselves as born-again were found to have less atrophy in the hippocampus region than did born-again Protestants, Catholics or those with no religious affiliation.

The science of protecting people’s feelings: why we pretend all opinions are equal It’s both the coolest — and also in some ways the most depressing — psychology study ever. Indeed, it’s so cool (and so depressing) that the name of its chief finding — the Dunning-Kruger effect — has at least halfway filtered into public consciousness. In the classic 1999 paper, Cornell researchers David Dunning and Justin Kruger found that the less competent people were in three domains — humor, logic, and grammar — the less likely they were to be able to recognize that. Or as the researchers put it:

Human Connectome Project The Human Connectome Project (HCP) is a five-year project sponsored by sixteen components of the National Institutes of Health, split between two consortia of research institutions. The project was launched in July 2009[1] as the first of three Grand Challenges of the NIH's Blueprint for Neuroscience Research.[2] On September 15, 2010, the NIH announced that it would award two grants: $30 million over five years to a consortium led by Washington University in Saint Louis and the University of Minnesota, and $8.5 million over three years to a consortium led by Harvard University, Massachusetts General Hospital and the University of California Los Angeles.[3] The goal of the Human Connectome Project is to build a "network map" that will shed light on the anatomical and functional connectivity within the healthy human brain, as well as to produce a body of data that will facilitate research into brain disorders such as dyslexia, autism, Alzheimer's disease, and schizophrenia.[4]

Time on the Brain: How You Are Always Living In the Past, and Other Quirks of Perception I always knew we humans have a rather tenuous grip on the concept of time, but I never realized quite how tenuous it was until a couple of weeks ago, when I attended a conference on the nature of time organized by the Foundational Questions Institute. This meeting, even more than FQXi’s previous efforts, was a mashup of different disciplines: fundamental physics, philosophy, neuroscience, complexity theory. Crossing academic disciplines may be overrated, as physicist-blogger Sabine Hossenfelder has pointed out, but it sure is fun. Like Sabine, I spend my days thinking about planets, dark matter, black holes—they have become mundane to me. But brains—now there’s something exotic.
