[Theta rhythm recorded in the hippocampal formation in vitro].
Theta rhythm is the best synchronized EEG activity that can be recorded in the mammalian brain. Hippocampal formation (HPC) is considered to be the main structure involved in the generation of this activity. Numerous data indicate that theta rhythm is involved in long-term potentiation, spatial learning, spatial navigation, verbal and spatial working memory, REM sleep, locomotor activities, and...
متن کاملFunctional Peculiarities of Hippocampal Theta-rhythm
The phenomenon of disappearance of the theta rhythm after lesioning of the septum and fornix has in its time stimulated a series of reports describing attempts to understand the roles of various structures in determining the electrical activity of the hippocampus and the functional significance of the theta rhythm. In chronic experiments with rabbits have shown that electrical destruction of do...
متن کاملHippocampal theta rhythm synchronizes visual neurons in sleep and waking.
The hippocampal theta rhythm (theta) was reported to be associated with movements, attention, auditory processing, autonomic functions, learning and memory and postulated as an associator of discontiguous events. Since visual information includes temporal cues, our study was centered on the correlation between hippocampal theta rhythm and lateral geniculate activity. Phase relationships between...
متن کامل[Gap junction involvement in hippocampal theta rhythm generation].
Hippocampal theta rhythm is probably the best example of oscillations and synchrony phenomena occurring in neuronal networks of the central nervous system. It is well known that intraneuronal communication via chemical and electrical synapses underlies these oscillatory processes. Despite well-documented knowledge concerning the participation of chemical transmission in production of theta acti...
متن کاملCholinergic/GABAergic interaction in the production of EEG theta oscillations in rat hippocampal formation in vitro.
The generation of EEG theta rhythm (RSA) in the hippocampal formation is a prime example of rhythmic activity involving central mechanisms of oscillation and synchrony. Cholinergic nature of the in vitro and in vivo induced RSA has been undoubtedly established. Recently, we have demonstrated in vitro that the hippocampal formation theta rhythm resulted from interaction between the cholinergic a...
