Researchers Uncover Two Brain Signals Involved In How Humans Predict Other Peoples’ Decisions

Researchers at the RIKEN Brain Science Institute (BSI) in Japan have uncovered two brain signals in the human prefrontal cortex involved in how humans predict the decisions of other people. Their results suggest that the two signals, each located in distinct prefrontal circuits, strike a balance between expected and observed rewards and choices, which enables […]

Cognitive Decline In Patients With Parkinson Disease Associated With Certain Patterns Of Brain Volume Decreases

Patients with Parkinson disease-related dementia appear to have increased brain atrophy in the hippocampal, temporal and parietal lobes and decreased prefrontal cortex volume compared to patients with Parkinson disease without dementia, according to a report in the December issue of Archives of Neurology, one of the JAMA/Archivesjournals. The study was conducted by Daniel Weintraub, M.D., […]

The Neurocognitive Connection Between Physical Activity And Eating Behavior

A healthy diet and the right amount of exercise are key players in treating and preventing obesity but we still know little about the relationship both factors have with each other. A new study now reveals that an increase in physical activity is linked to an improvement in diet quality. Many questions arise when trying […]

Researchers Characterize Epigenetic Signatures Of Autism In Brain Tissue

Neurons in the prefrontal cortex of individuals with autism show changes at numerous sites across the genome, according to a study being published Online First by the Archives of General Psychiatry, one of the JAMA/Archives journals. The study was carried out by Hennady P. Shulha, Ph.D., of the University of Massachusetts Medical School, Worcester, Mass., […]

Disinhibited Brains And Behavior May Be Related To Lower GABA In The Pre-Frontal Cortex

Impulsive individuals tend to display aggressive behavior and have challenges ranging from drug and alcohol abuse, to problem gambling and difficult relationships. They are less able to adapt to different social situations. Impulsivity is also a common feature of psychiatric disorders. New research in Biological Psychiatry shows that people may react this way, in part, […]

Nicotine Receptors In The Brain Make Important Contributions To Social Behavior

If you think nicotine receptors are only important to smokers trying to kick the tobacco habit, think again. New research published in the FASEB Journal suggests that these receptors also play an important role in social interaction and the ability to choose between competing motivations. Specifically, scientists from France show that the nicotinic receptors in […]
