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.
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.
A new study reveals the role synaptic feedback systems play in shaping learning processes. The findings could help develop more efficient artificial intelligence techniques.
Researchers have identified a novel role the RGS14 protein plays in limiting synaptic plasticity.
Researchers report running can help mitigate the impact chronic stress has on the hippocampus.
A new study reveals the piriform cortex is able to archive long term memory, but requires instruction from the orbiotfrontal cortex to indicate the event is to be stored as a long-term memory.
