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 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.
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.
Binghampton University researchers report women with a history of suicide attempts express lower levels of BDNF, a protein critical for the creation and function of neurons, in their bloodstream. Researchers believe the level of BDNF found in the circulatory system may be a biomarker for suicidal behavior.
