Abstract

We examined the electrophysiological properties of cholinergic and non-cholinergic neurons in the medial septum-diagonal band complex (MSDB) of the rat in the in vitro slice preparation. Cells were identified electrophysiologically, filled with Lucifer yellow, fixed and processed for immunohistochemistry with fluorescent labeled anti-choline acetyltransferase (ChAT) antibody. Cholinergic and non-cholinergic neurons differed in action potential parameters, spike afterpotentials and in current-voltage relationships. In addition, cholinergic neurons expressed a potent transient outward rectification in response to a depolarizing current pulse.

Electrophysiology

Electrophysiology (from Greek ἥλεκτ, ēlektron, "amber" [see the etymology of "electron"]; φύσις, physis, "nature, origin"; and -λογία, -logia) is the branch of physiology that studies the electrical properties of biological cells and tissues. It involves measurements of voltage changes or electric current or manipulations on a wide variety of scales from single ion channel proteins to whole organs like the heart. In neuroscience, it includes measurements of the electrical activity of neurons, and, in particular, action potential activity.

Striatum

The striatum, or corpus striatum (also called the striate nucleus), is a nucleus (a cluster of neurons) in the subcortical basal ganglia of the forebrain. The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia. Functionally, the striatum coordinates multiple aspects of cognition, including both motor and action planning, decision-making, motivation, reinforcement, and reward perception.

Action potential

An action potential occurs when the membrane potential of a specific cell rapidly rises and falls. This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in several types of animal cells, called excitable cells, which include neurons, muscle cells, and in some plant cells. Certain endocrine cells such as pancreatic beta cells, and certain cells of the anterior pituitary gland are also excitable cells.
