Medial septal cholinergic mediation of hippocampal theta rhythm induced by vagal nerve stimulation.

Summary of "Medial septal cholinergic mediation of hippocampal theta rhythm induced by vagal nerve stimulation."

Electrical vagal nerve stimulation (VNS) has been used for years to treat patients with drug-resistant epilepsy. This technique also remains under investigation as a specific treatment of patients with Alzheimer's disease. Recently we discovered that VNS induced hippocampal formation (HPC) type II theta rhythm, which is involved in memory consolidation. In the present study, we have extended our previous observation and addressed the neuronal substrate and pharmacological profile of HPC type II theta rhythm induced by VNS in anesthetized rats.

GABAergic mediation of hippocampal theta rhythm induced by stimulation of the vagal nerve.

The key question to be answered in the present study was whether the medial septal GABAergic receptors are engaged in the pharmacological profile of VNS-induced hippocampal theta rhythm. It was demons...

Medical and Biotech [MESH] Definitions

Neural nuclei situated in the septal region. They have afferent and cholinergic efferent connections with a variety of forebrain and brainstem areas including the hippocampus, the lateral hypothalamus, the tegmentum, and the amygdala. Included are the dorsal, lateral, medial, and triangular septal nuclei, septofimbrial nucleus, nucleus of diagonal band, nucleus of anterior commissure, and the nucleus of stria terminalis.

One of four types of brain waves, characterized by a frequency of 4-7 Hz, usually observed in the temporal lobes when the individual is awake, but relaxed and sleepy.

The ligament that travels from the medial epicondyle of the FEMUR to the medial margin and medial surface of the TIBIA. The medial meniscus is attached to its deep surface.

Drugs that bind to but do not activate CHOLINERGIC RECEPTORS, thereby blocking the actions of ACETYLCHOLINE or cholinergic agonists.

Gray matter structures of the telencephalon and limbic system in the brain, but containing widely varying definitions among authors. Included here is the cortical septal area, subcortical SEPTAL NUCLEI, and the SEPTUM PELLUCIDUM. Many authorities consider the septal region to be made up of the septal area and the septal nuclei, but excluding the septum pellucidum.
