Visceral fat impairs memory via proinflammatory interleukin-1 beta mediated microglia activation in the hippocampus.
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.
A new study sheds light on how the brain processes rewards and provides a deeper understanding on the neurobiology of depression.
Researchers have identified a novel role the RGS14 protein plays in limiting synaptic plasticity.
Researchers report molecular networks on both sides of a synapse are important for controlling learning.
According to researchers, some synapses get smaller as we learn new information.
The strength of a memory depends upon the number of receptors in a synapse, researchers report.
Researchers report running can help mitigate the impact chronic stress has on the hippocampus.
Researchers report alcohol seeking behavior may be induced by altering the strength of synapses.
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.
