Strength training may negatively impact endurance muscles. BDNF, which is increased during strength training and helps strength muscles to develop, decreases endurance muscle fibers.
Contradicting previous studies, UC Boulder researchers report there is no clear evidence of any candidate gene associated with depression.
Adolescent rats exposed to alcohol had a decrease of both Arc eRNA expression and Arc gene expression in the amygdala during adulthood. Additionally, the alcohol-exposed rats displayed increased anxiety behaviors as they aged.
Researchers report estrogen may play a significant role in synaptic plasticity and memory formation. The study reports mice whose neurons did not produce estrogen have impairments in spatial reference memories, recognition and contextual fear memories. Restoring estrogen levels assisted in reversing the memory impairments, the study revealed.
Researchers report fear extinction memories form as a result of an adenosine modification, which help to increase the activity of specific genes.
Researchers report a signalling mechanism in the brain shapes social behavior. The findings may have implications for better understanding social hierarchies, aggression and bullying.
Researchers report exercise can promote adult hippocampal neurogenesis and improve cognition in mouse models of Alzheimer's disease. The study identifies ways to mimic the beneficial effects of experience through pharmacological and gene therapy.
Researchers report the gamma-CaMPII protein plays a critical role in learning and memory. The shuttle protein may be dysfunctional in those with Schizophrenia and autism, hindering learning abilities, researchers report.
A new study reports increased levels of STEP in the hippocampus is linked to mild cognitive impairment.
Researchers report running can help mitigate the impact chronic stress has on the hippocampus.
A new study reveals exposure to dim light might impact memory and learning. Researchers report rodents exposed to dim lighting lost 30 percent of hippocampal capacity and performed poorly on spatial tasks they had previously experienced.
EGR3 and BDNF may play a critical role in the impaired cellular resilience seen in bipolar disorder, researchers report.
