How Gene Expression Controls Synaptic Plasticity in the Aging Human Brain

M1 muscarinic acetylcholine receptor (mAChR) dependent LTP and LTD share a common AMPA trafficking pathway. Either the upregulation of neurotransmitter receptor genes or suppression of the downregulation could improve synaptic dysfunction associated with age-related neurodegeneration. The findings could assist in the creation of new therapies for Alzheimer's disease that target synaptic plasticity.

A Novel Instructive Role for the Entorhinal Cortex

Researchers have identified a new type of synaptic plasticity they call behavioral timescale synaptic plasticity (BTSP). The study reveals how the entorhinal cortex sends instructive signals to the hippocampus and directs it to specifically reorganize the specific location and activity of a neural subset to achieve altered behavior in response to changes in environment and spatial cues.
