Distinct information about familiar faces is encoded in a neural code that is shared across brains, according to a new study published in the Proceedings of the National Academy of Sciences.

A new study conducted in adults with a history of childhood maltreatment showed that two groups – those with a history of sexual abuse and those with posttraumatic stress disorder (PTSD) – had reduced brain connectivity in the attention systems known as the ventral and dorsal attention network (VAN-DAN).

New findings reveals dopamine neurons that play a role in learning and memory also drive motivation.

For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implications for the development of potential treatments.

Musical therapy can help to improve fine motor skills in patients with Parkinson’s disease according to new research. 

A genetic predisposition for depression combined with exposure to high-particulate-matter air pollution greatly elevates the risk that healthy people will experience depression, according to a first-of-its-kind study published in the Proceedings of the National Academies of Sciences (PNAS).

Recently published research found people who continued to spend a higher amount of time sitting between April and June 2020 were likely to have higher symptoms of depression.

A new study, published in the International Journal of MS Care, found that the vibration training improved not only physical symptoms associated with multiple sclerosis, such as increased walking speeds, but also cognitive functions, such as memory capacity and executive function.

A newly developed AI algorithm can directly predict eye position and movement during an MRI scan. The technology could provide new diagnostics for neurological disorders that manifest in changes in eye-movement patterns.

A team of researchers has found a possible connection between depression and anxiety for IBD patients and the vascular barrier in the brain choroid plexus closing. In their paper published in the journal Science, the group describes their study of the gut-brain axis response to inflammation and its link to psychiatric illnesses.

Researchers have created the first body map of sensations experienced during hallucinations in people experiencing psychosis.

Recent resarch reveals the severity of PTSD symptoms was associated with fewer risky choices and increased activation of the amygdala. Decreased activity in the ventral striatum, an area of the brain associated with processing positive valence such as reward, predicted more severe PTSD symptoms 14 months post-trauma.

Finally this week, people who consume a diet containing anti-inflammatory foods, including fruits, vegetables, and coffee, are less likely to develop dementia as they age, a new study reports.
