A single head injury can increase the risk of developing dementia, especially in women. Suffering more than one head injury increases the risk further, a new study reports.
Neuroimaging revealed when people saw an anomalous face, the fusiform gyri and amygdala showed significant neural responses. Activity in a region of the left amygdala, which correlated with less pro-social responses to the anomalous face, appeared to relate to the participant's belief about justice in the world and their degree of empathetic concern.
Young adults are more likely to recall and share information pertaining to politics and government policy if it is presented in a humorous, entertaining manner.
During decision-making tasks, activation of two brain areas in rhesus macaques mirrors the same regions as in humans. The findings shed light on the neurobiological basis of cooperation and social interactions during decision-making tasks.
New artificial intelligence technology will analyze clinical data, brain images, and genetic information from Alzheimer's patients to look for new biomarkers associated with the neurodegenerative disease.
c9ASO, an investigational ASO drug, targets the TDP-43 protein, reducing its buildup and decreasing neurological decline associated with ALS and FTD.
Compared to typically developing children, those with disruptive behavioral disorders, characterized by antisocial behaviors and aggression, had less gray matter in the amygdala and hippocampus.
Both food timing and the integrity of the internal clock in the liver altered rhythms of metabolism in mice. Almost half of the rhythmic genes are regulated by both the internal clock and when food is ingested.
Researchers successfully applied a gene therapy platform to completely correct brain defects in a large animal model of a human genetic disease.
The loss of the protein neurofibromin 1 (NF1) in adult male flies resulted in social impairments. The deficits were traced back to a primary disruption in a small group of peripheral neurons which control external stimuli, including touch and smell, that communicate to the brain.
HIV infection leads to increased EIF2 signaling in microglia, astrocytes, and neurons. Study reveals how HIV infection and some antiretrovirals affect cognition and the central nervous system.
Dantrolene, a common muscle relaxant, shows promise in the treatment of Alzheimer's disease. Mice administered the drug intranasally had higher concentrations of the medicine in their brains, and for longer periods, than those who received it orally. The drug has been shown to help inhibit or slow the progression of several neurodegenerative diseases.
