Cannabidiol Shows Sustained Effects Against Depression for Seven Days: Rat Study
A study using rat models of depression reveals a single dose of the cannabis extract CBD can help to reduce symptoms of depression for up to one week. Researchers say cannabidiol appears to activate mechanisms that help repair neural circuitry in the prefrontal cortex and hippocampus, which get damaged as a result of depression.... Read More...
PSD as a Molecular Platform For Understanding Synapse Formation and Plasticity
A new study reports that both in solution and on supported membrane bilayers, multivalent interaction networks formed by major excitatory postsynaptic density scaffold proteins led to formation of PSD-like assemblies via phase separation.... Read More...
How Experience Changes Basics of Memory Formation
Researchers report animals with previous conditioned experiences form memories using different plasticity mechanisms to naive subjects, even if they are about to learn the same thing.... Read More...
New Neurons Archive Old Memories
Researchers report neurogenesis underlies the brain's capacity to create and store new memories. Exercise, researchers report, promotes neurogenesis and increases hippocampal capacity.... Read More...
New Software Designed for Rapid and Automated Identification of Dendritic Spines
Researchers have developed a new machine learning algorithm that can autonomously and efficiently identify dendritic spines with 90% accuracy.... Read More...
Broken Shuttle May Interfere with Learning in Brain Disorders
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.... Read More...
Fundamental Rule of Brain Plasticity Discovered
Based on the actions of Arc, when one synapse strengthens, the neighboring synapses weaken, a new study reveals. ... Read More...
Brain Changes Linked to Sleep Needed
A new study sheds light on the biochemistry of sleep need in the brain.... Read More...
Mapping Memory
A new study sheds light on how our brain stores long term spatial memories. Researchers have identified a specific pattern of neural activity in the retrosplenial cortex when our brains are in the process of storing spatial memories.... Read More...
