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.
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.
Researchers have identified two brain pathways that appear to be critical in determining how mice react to visual threats. The findings could have implications for treating PTSD and phobias in humans.
New understanding about ketamine's antidepressant effect could lead to the development of new, safer and quicker ways to treat depression.
Researchers report connections between the hippocampus and a specific type of neuron in the prefrontal cortex are involved in fear relapse. The findings could help in the development of new treatments for PTSD.
Researchers report episodic memory function becomes disrupted when neural pathways that allow communication between the hippocampus and prefrontal cortex are deactivated.
Researchers have discovered a brain network that appears to be involved in self disclosure in social networks.
