New region in human brain discovered.

World-renowned cartographer of the brain, Scientia Professor George Paxinos, Conjoint Professor at UNSW, has discovered a hidden region of the human brain. The region is found near the brain-spinal cord junction and Professor Paxinos has named it the Endorestiform Nucleus. /…/

The Endorestiform Nucleus is located within the inferior cerebellar peduncle, an area that integrates sensory and motor information to refine our posture, balance and fine motor movements. /…/

mind altering drugs

there’s a list of science discoveries out there made by scientists under the influence of drugs. some say that the drugs helped them to make the discoveries. i think those who say drugs were of help missed the whole point — those scientists were smart enough that even drugs didn’t mess up all their brain cells and they made the discoveries not because of the drugs but despite of them. imagine what more they could have achieved in science if they didn’t take drugs. and in some cases it may just have been a lucky coincidence — even a broken clock is right twice a day.

Researchers find potential therapy for brain swelling during concussion.

A team of biomedical engineering researchers at the University of Arkansas have identified a cause of fluid swelling of the brain, or cellular edema,that occurs during a concussion. The researchers discovered that pre-treating the cells with an existing, FDA-approved drug used for epilepsy and altitude sickness reduces the expression of a specific protein that causes swelling.

Scientists discover neuron-producing stem cells in the membranes covering the brain.

Unexpected cells have been found in the protective membranes that enclose the brain, the so called meninges. These ‘neural progenitors’ — or stem cells that differentiate into different kinds of neurons — are produced during embryonic development. These findings show that the neural progenitors found in the meninges produce new neurons after birth — highlighting the importance of meningeal tissue as well as these cells’ potential in the development of new therapies for brain damage or neurodegeneration.

Three brain chemicals affect how we handle uncertainty.

New research has revealed how three important brain signaling chemicals affect the way that we handle uncertainty. It turns out that noradrenaline regulates our estimates of how unstable the environment is, acetylcholine helps us adapt to changing environments, and dopamine pushes us to act on our beliefs about uncertainty. The research, publishing 15 November in the open-access journal PLOS Biology, was led by Louise Marshall and Dr Sven Bestmann at the UCL (University College London) Institute of Neurology.

More GABA in one brain region linked to better working memory, scientist says.

The amount of a particular chemical in a particular part of your brain predicts your ability to simultaneously hang onto several bits of information in your working memory, a Stanford University School of Medicine scientist and his University of California-Davis collaborators have learned. The discovery helps to clarify at least one aspect of the brain’s mysterious ways, and could someday help guide therapies for those whose working memory could stand improvement.

“No previous study has ever pinpointed GABA’s link with working memory in humans,” said Yoon. “Working memory is a complex process, requiring coordinated activity in centers throughout the brain. Yet, remarkably, the amount of this one chemical in a single part of the brain accounts for close to one-third of the variance in individuals’ load capacity.”
