A new study found altered cortical and subcortical networks in those with schizophrenia and their unaffected first-degree relatives. Findings suggest brain regions associated with a genetic predisposition to schizophrenia are partly separated from brain regions implicating neural abnormalities.
How do we make decisions during times when we are uncertain? A new study may have clues. Researchers identified a specific set of neurons that prevent the brain from using unreliable information when faced with decision-making.
Withdrawal from psychostimulants including methamphetamines, cocaine, and nicotine, produced restructuring of brain regions and major increases in functional connectivity, a new mouse study reveals.
A study spanning 17 years has found children born and raised in poverty had smaller subcortical brain regions, including the hippocampus, caudate, putamen, and thalamus. These brain areas also showed less growth over time.
Findings reveal how individual neurons in the thalamus can merge signals coming from different regions of the cortex. The findings could lead to new treatment options for schizophrenia, epilepsy, and other brain disorders where thalamus dysfunction is related to clinical symptoms.
Propofol, the commonly used anesthetic, alters and controls the dynamics of the brain's rhythms. The findings can help doctors better monitor patients under anesthesia with the aid of EEG.
A brain network consisting of the thalamus, anterior and posterior cingulate cortex, and angular gyri was implicated in the loss, and return, of consciousness under both anesthetic and natural sleep.
People make automatic and efficient decisions when learning to avoid others. When learning to avoid harming themselves, people make become more deliberative. The study also found people were more willing to repeat decisions that were previously harmful to themselves if they believed better results would occur in the future.
Working memory isn't confined to one area of the brain. It requires synchronous activity of at least two brain areas.
