Researchers have revealed a new, non-invasive, pre-clinical biomarker for Alzheimer's disease.
A positive correlation has been identified between prosocial and rebellious behaviors in teens. The more risk taking behaviors a teen exhibited, the more likely they were to act prosocially. The findings suggest the same developmental processes are at work for both types of behaviors. Also noted was faster brain development in the medial prefrontal cortex predicted a decrease in rebellious behavior.
Researchers report older people may make riskier decisions than younger people.
Aging may alter neural processes for remembering continuous real-world experiences and segmenting memories.
Researchers report alcohol can strengthen fearful memories, but a drug used to treat seizures may reverse the effects.
According to a new study to be published in eNeuro, amphetamine use may disrupt the development of the orbital prefrontal cortex, an area of the brain associated with decision making.
Reducing the excitation-inhibition ratio by diminishing excitability of pyramidal neurons or increasing excitability of PV neurons led mice to spend more time engaged in social encounters. Researchers believe the excitation-inhibition balance may play a key role in autism and normal social behavior.
Study reveals how two neural circuits dictate the choice between social approach and avoidance. The network connecting the infralimbic cortex to the basolateral amygdala (BLA) impairs social behavior if there is a decrease in neural activity. Another network connecting the prelimbic cortex to the BLA similarly impairs social behavior if the neural activity is increased.
