Theta rhythm recorded as an extracellular synchronous field potential is generated in a
number of brain sites including the hippocampus. The physiological occurrence of …

The posterior hypothalamic area (PHa), including the supramammillary nucleus (SuM) and
posterior hypothalamic nuclei, forms a crucial part of the ascending brainstem hippocampal …

Theta phase‐locking and phase precession are two related phenomena reflecting
coordination of hippocampal place cell firing with the local, ongoing theta rhythm. The …

Stimulation of a neural pathway originating in the brainstem reticular formation, with
synapses in the medial hypothalamus, activates the hippocampal theta rhythm. The …

Theta rhythm is the largest, most prominent, and well‐documented electroencephalography
activity present in a number of mammals, including humans. Spontaneous theta activity …

ABSTRACT Kowalczyk et al.(Hippocampus 2014; 24: 7‐20) were probably the first to
conduct a systemic study of posterior hypothalamic area (PHa) theta rhythm in anesthetized …

Recent evidence suggests that the supramammillary nucleus of the posterior hypothalamus
serves as an important relay in the brainstem to septum/hippocampus pathway involved in …

This article summarizes the results of studies concerning the influence of the ventral
tegmental area (VTA) on the hippocampal theta rhythm. Temporary VTA inactivation resulted …

The theta rhythm is the largest extracellular synchronous signal that can be recorded from
the mammalian brain and has been strongly implicated in mnemonic processes of the …

Experiments were carried out for the purpose of comparing the electrophysiological
properties of spontaneously occurring hippocampal theta field activity with those of theta …
