"The outer layer of brain, also called the cerebral cortex or gray matter, controls most complex mental activities," explained Clive Harper, symposium organizer and professor of neuropathology at the University of Sydney and Royal Prince Alfred Hospital. "The cortex is filled with nerve cells, also ca...

Methamphetamine Abuse, HIV Infection Cause Changes in Brain Structure

... is associated with prominent volume losses in the cerebral cortex (involved in higher thought, reasoning, and memory), basal ganglia, and hippocampus (involved in memory and learning). The scientists stress that among the recent methamphetamine abusers in the study, the degree of volume increase in the pari...

Bigger brain size matters for intellectual ability

...the contribution of nature and nurture are to this cerebral size relationship with intelligence, Witelson said. She added that the results point to the need for responsibility in considering the likely future use of magnetic imaging (or MRIs) of brain structure as a measure of ability in student and workforce...

Blocking the nerve receptor EP1 in mouse models reduces brain damage caused by stroke

...k by others had shown that certain events, such as cerebral ischemia (stroke) and seizures, that interrupt oxygen flow to the brain also cause excessive activation of so-called NMDA receptors by the nerve chemical glutamate. Other work had suggested that activation of NMDA receptors by glutamate causes an inc...

Neurons generated in the adult brain learn to respond to novel stimuli

... form some of the much more complex neurons in the cerebral cortex, the brain's highest-level structure. The current study was designed to investigate whether newly generated olfactory neurons simply replace older neurons or play a distinct role in learning and memory. The investigators used two groups of m...

Meditation associated with structural changes in brain

...H) researchers showed that particular areas of the cerebral cortex, the outer layer of the brain, were thicker in participants who were experienced practitioners of a type of meditation commonly practiced in the U.S. and other Western countries.

MIT researcher presents new view of how the cortex forms

The cerebral cortex is a sheet of around 10 billion neurons divided into distinctly separate areas that process particular aspects of sensation, movement and cognition. To what extent are these areas predetermined by genes or shaped by the environment? The protom...

What can change in the brain? Electrical synapses, research shows

...esponsible for relaying sensory information to the cerebral cortex, where it is transformed into memories and emotions, speech and movement. The thalamic reticular nucleus' role as a sort of switch, starting or stopping the flow of sensory stimuli to the cortex, may implicate it as a major player in the regu...

Neurons find their place in the developing nervous system with the help of a sticky molecule

The cortex sits like a skullcap over the rest of the brain and is responsible for sensory perception, higher-level reasoning, and, in humans, language. In mammals, the largest and evolutionarily newest part of the cortex, the neocortex, is re...
