Interaction between theta phase and spike timing-dependent plasticity simulates theta-induced memory effects
Rodent studies suggest that spike timing relative to hippocampal theta activity determines
whether potentiation or depression of synapses arise. Such changes also depend on spike …

Phasic modulation of hippocampal synaptic plasticity by theta rhythm.
LS Leung, CSH Law - Behavioral Neuroscience, 2020 - psycnet.apa.org
Theta rhythm and long-term potentiation (LTP) are 2 remarkable discoveries. The theta
rhythm is an oscillatory neural activity of 3–10 Hz in the hippocampus. LTP is implicated as a …
