Researchers identified a new mechanism by which auditory sensitivity is regulated. The mechanism can temporarily reduce sensitivity in the auditory system to protect itself from loud sounds that can cause hearing damage.
The protein tubulin blocks molecules that trigger the production of cAMP, leading to reduced messaging in the brain. Previous studies have found those with depression have less cAMP in their brains. The findings suggest tubulin could be a potential biomarker for depression.
Environmental light has been shown to affect traumatic long-term memory retention in Drosophila.
Mouse study reveals a gene that influences memory recall at different times of the day. Researchers identified how the gene causes mice to be more forgetful just before they normally wake.
A mechanism that links exposure to high-fat diets in mice to changes in hypothalamic function which leads to depression has been identified. Saturated fatty acids enter the brain via the bloodstream, where they accumulate and affect key signaling pathways associated with the development of depression.
Researchers explore the mechanisms behind ketamine's effectiveness at treating depression. The study reports the long lasting effects of ketamine may be due to G proteins timing in moving back to lipid rafts.
Study reveals how the mechanism for storing olfactory memories differs slightly from erasing unnecessary memories. Understanding how the brain gets rid of unimportant memories could help unlock new avenues of research to better understand memory loss in aging, researchers say.
Hordenine, a substance present in beer and malted barley, activates dopamine D2 receptors through G proteins, leading to a possibly prolonged effect on the brain's reward center, researchers report.
Researchers have identified a compound that appears to enhance long term memory.
A new study reveals animals injected with caffeine during the last 10 minutes of exposure to general anesthetic woke more quickly than those injected with saline solution. Waking times became significantly quicker with higher doses of caffeine.
Researchers have discovered 24 compounds, including caffeine, that have the potential to boost NMNAT2, an enzyme shown to help protect against dementia.
A new study explores how neural activity influences CREB dynamics.
