A newly developed brain atlas could help with the study and diagnosis of mental health and neurodegenerative disorders by correlating brain networks with underlying anatomical structures.
Researchers have developed a new method to measure the delay of neurotransmission in those with multiple sclerosis that does not involve direct stimulation but instead used neural avalanches, or bursts of activity in cascades that spontaneously travel across the brain.
Psychostimulants increase dopamine levels, enhancing task-relevant cortical signals by acting on the striatum and the difference in dopamine synthesis capacity in the striatum explains the variability in the drugs' cognitive effects.
Researchers have mapped four new areas of the human anterior prefrontal cortex that play critical roles in cognitive processing. Two of these newly mapped areas are larger in females than in males.
Volume decreases in cortical areas, the amygdala, and basal forebrain in Parkinson's patients correlated with worsening symptoms of the disease.
Using whole-brain virtual models, researchers simulate the effects of non-invasive neurostimulation on the aging brain. The computational models shed light on the dynamics of brain changes as a result of aging.
