Visceral fat delivers signal to the brain that hurts cognition
Visceral fat impairs memory via proinflammatory interleukin-1 beta mediated microglia activation in the hippocampus.... Read More...
long-term potentiation
Quick thinking? It’s all down to timing
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
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...
