3-D models of neuronal networks reveal organizational principles of sensory cortex

Researchers have succeeded in reconstructing the neuronal networks that interconnect the elementary units of sensory cortex — cortical columns. The scientists say that this study marks a major step forward to advance the understanding of the organizat…

Researchers observe the moment when a mind is changed

Researchers studying how the brain makes decisions have, for the first time, recorded the moment-by-moment fluctuations in brain signals that occur when a monkey making free choices has a change of mind. This basic neuroscience discovery will help crea…

Nail biters, beware: Teeth grinding is next

Anxiety disorders affect approximately one in six adult Americans. The most well-known of these include panic disorder, post-traumatic stress disorder, obsessive-compulsive disorder, and social anxiety disorder. But what of brief bouts of anxiety cause…

Traumatic brain injury linked to increased road rage

Ontario adult drivers who say they have experienced at least one traumatic brain injury in their lifetime also report significantly higher incidents of serious road-related driving aggression, said a new study. Serious driver aggression includes: makin…

Say what? How the brain separates our ability to talk and write

Although the human ability to write evolved from our ability to speak, writing and talking are now such independent systems in the brain that someone who can’t write a grammatically correct sentence may be able say it aloud flawlessly.

Strategy found for safely prescribing antidepressants to children and adolescents

Two new strategies to treat depression in young people have been developed for the use of selective serotonin reuptake inhibitor class of medications. These strategies incorporate a new understanding of how to mitigate the risk of suicide while on SSRI…

‘Tangles’ trigger early-stage Alzheimer’s abnormalities in neocortical networks

A ground-breaking study has now, for the first time, characterized early-stage changes that occur inside individual, Alzheimer’s-affected cells in the intact brain. Remarkably, the study indicates that even if only a small number of cells is affected, …

Accelerated brain aging in type 1 diabetes related to cognitive complications

The brains of people with type 1 diabetes show signs of accelerated aging that correlate with slower information processing, according to research. The findings indicate that clinicians should consider screening middle-aged patients with type 1 diabete…

Proteomics provides new leads into nerve regeneration

Using proteomics techniques to study injured optic nerves, researchers have identified previously unrecognized proteins and pathways involved in nerve regeneration. Adding back one of these proteins — the oncogene c-myc — they achieved unprecedented …
