Older people have longer reaction times, slower decision times, and greater activation in brain areas involved in inhibition and task switching. The findings may shed light on why many older drivers mistake the accelerator for the brake pedal.
Researchers have identified a brain circuit that drives physical response to emotional stress. The circuit begins in the dorsal peduncular cortex and dorsal tenia tecta, before sending signals to the hypothalamus. The findings could help with the development of treatments for panic disorders and PTSD.
Fish model study found a potential target for the treatment of seasonal affective disorder (SAD). Researchers implicated NRF2 in seasonal depression and reported celastrol may help in the treatment of SAD.
Microglia initially protects the blood-brain barrier from damage due to systemic inflammation. However, microglia can alter their behavior and increase the permeability of the blood-brain barrier, thus damaging it.
Researchers have developed a novel tool to help monitor metabolites in the brain in real time.
Researchers shed light on thermoregulation by disabling parts of rat brains and observing their choice of a comfortable environmental temperature. The findings could provide new understanding of conditions such as heatstroke.
