New insight into how obesity and insulin resistance can impair cognition

Neuroscience NewsApril 22, 2019

Adora2a mediating signaling in vascular endothelial cells disrupts the blood-brain barrier in obesity. This, researchers report, could be an underlying mechanism for synaptic plasticity and cognitive deficits in those with insulin resistance and obesity.... Read More...

A detailed drawing of the hippocampal formation is shown.

Quick thinking? It’s all down to timing

Neuroscience NewsMarch 27, 2019

A pairing of presynaptic and postsynaptic activity in a population of hippocampal neurons can reduce the required number of synaptic plasticity evoking events. When spikes occur within ten milliseconds of each other, synapses strengthen for up to four hours.... Read More...

Estrogen Made by Neurons Important to Memory Making

Neuroscience NewsFebruary 25, 2019

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.... Read More...

Cannabidiol Shows Sustained Effects Against Depression for Seven Days: Rat Study

Neuroscience NewsAugust 31, 2018

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...
