Comprehensive Profiling of Dopamine Regulation in Substantia Nigra and Ventral Tegmental Area
Published on: August 10, 2012
Abstract:
Autoradiography following administration of 2-deoxy-[14C]glucose has shown that penicillin-induced epileptic foci in the cerebral cortex selectively coactivate associated neostriatal regions. The present material demonstrates that this coactivation may appear in patches in the rat neostriatum. Activity from a cortical area seems to spread first to islands of the associated neostriatal region and may either spread gradually to the surrounding 'matrix' or not involve the 'matrix' for tenths of minutes. The regionally restricted functional patchiness lends additional support to the notion that the neostriatum, like the neocortex, can be divided into regions which consist of modules.

Nervous Tissue: Neuron Types
Structurally, neurons are categorized into three main types: multipolar, bipolar, and unipolar (or pseudounipolar). Multipolar neurons, which are the most common type in the brain and spinal cord, as well as all motor neurons, possess multiple dendrites and a single axon.
Bipolar neurons, on the other hand, have one primary dendrite and one axon. They are...
