Our understanding of brain activity has traditionally been linked to brain areas – when we speak, the speech area of the brain is active. New research by an international team of psychologists shows that this view may be overly rigid. The entire cortex, not just the area responsible for a certain function, is activated when a given task is initiated. Furthermore, activity occurs in a pattern: waves of activity roll from one side of the brain to the other.
A new study has shown that a drug widely used to treat Parkinson’s Disease can help to reverse age-related impairments in decision-making in some older people.
Researchers have discovered that the extra chromosome inherited in Down syndrome impairs learning and memory because it leads to low levels of SNX27 protein in the brain.
A new study published in Nature reveals some of the dynamics of neural activity when people articulate syllables commonly used in English.
A new study suggests that migraines are related to brain abnormalities present at birth and others that develop over time. The research is published online in the journal Radiology.
A research team studying alcohol addiction has new research that might shed light on why some drinkers are more susceptible to addiction than others.
