This review summarizes data on the plasticity of hippocampal synaptic pathways in
conditions of afferent activation modeling the electrical activity of neurons during the theta …

Background Theta rhythm in the hippocampal formation is a main feature of exploratory
behaviour and is believed to enable the encoding of new spatial information and the …

A modulatory role for the hippocampal theta rhythm in synaptic plasticity is suggested by the
observations that theta occurs during exploratory behaviors, spatial learning is impaired …

A role for oscillatory activity in hippocampal neuronal networks has been proposed in
sensory encoding, cognitive functions and synaptic plasticity. In the hippocampus, theta (5 …

In the hippocampus in vivo, both synaptic plasticity and network activity are closely
interdependent. We have found that immediately after an attempt to induce long-term …

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 …

Hippocampally-driven oscillatory activity at theta frequency is found in the diencephalon, but
an understanding of the fundamental role of theta in the hippocampo-diencephalic circuit …

Cellular activity in the CA1 area of the hippocampus waxes and wanes at theta frequency (4–
8 Hz) during exploratory behavior of rats. Perisomatic inhibition onto pyramidal cells tends to …

Long-term potentiation (LTP) of synaptic transmission induced by high-frequency stimulation
(HFS) is considered to be a model for learning processes; however, standard HFS protocols …

The hippocampal synapses display a conspicuous ability for long‐term plasticity, which is
thought to contribute to learning and memory. Previous research has shown that long‐term …
