Brain imaging studies shed new light on social behaviors such as empathy and team flow. The findings provide new understanding of the neural basis of social behaviors and conditions involving social dysfunction.
According to a new Journal of Neuroscience study, strong structural connectivity between the rostrolateral prefrontal cortex and inferior parietal lobe in young children is associated with improved reasoning in adulthood.
Impaired blood flow to specific areas of the brain coincides with Tau buildup in Alzheimer's patients. As cognition declines, the relationship between vascular dysfunction and Tau accumulation strengthens.
Researchers report the same subset of neurons encode actual and illusory flow motion, supporting the concept Jan Purkinje proposed 150 years ago, that "illusions contain visual truth".
Exercise increases levels of galanin in the brain stem, making mice more resilient to stress.
Foxes bred to be either tame or aggressive had increased size in similar brain regions, a new study reports. The animals bred for specific behavioral traits had larger brains than those that were conventionally bred. The findings contradict existing theories of animal domestication.
Chemically activating neurons and placing mice in stimulating environments reverses alterations and restores some neural connectivity in frontotemporal dementia. If translated into humans, the findings could help develop new treatments for fighting the effects of dementia in the elderly.
Researchers say THC can impair or improve memory depending on age and disease. Findings suggest, in Alzheimer's disease, the cannabis compound can help improve memory and mitigate some of the symptoms of the disease.
Those on the autism spectrum had atypically smaller pupil dilation compared to the control group during distracting conditions while taking a push-button test. The findings suggest those with ASD may have dysregulation in locus coeruleus activity. The dysregulation of the LC may explain the exaggerated responses to environmental stimuli and fixated behaviors many with ASD experience.
