Researchers have made an important discovery about the mechanisms behind learning and memory. Depending on the number of synapses, and their proximity, information is processed and stored differently.
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.
Findings could help in the development of new prevention options and treatments for drug addiction, researchers report.
A new study reports cannabis can prune synapses and destroy some neural circuits.
