[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 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 کاملInvolvement of GABAergic and cholinergic medial septal neurons in hippocampal theta rhythm.
Hippocampal theta rhythm (HPCtheta) may be important for various phenomena, including attention and acquisition of sensory information. Two types of HPCtheta (types I and II) exist based on pharmacological, behavioral, and electrophysiological characteristics. Both types occur during locomotion, whereas only type II (atropine-sensitive) is present under urethane anesthesia. The circuit of HPCth...
متن کاملSepto-hippocampal networks in chronically epileptic rats: potential antiepileptic effects of theta rhythm generation.
A series of experiments was carried out testing the hypothesis that the septal region decreases the hippocampal susceptibility to hyperexcitability states through theta rhythm generation. Medial septal neurons were simultaneously recorded with hippocampal field potentials to investigate the septo-hippocampal function in the pilocarpine model of chronic epilepsy. The theta rhythm from chronicall...
متن کامل[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...
