LOCAL CIRCUIT NEURON
Local Circuit Neurons: An Overview The human brain is one of the most complex and mysterious objects in existence. It is composed of billions of neurons, which are organized into a variety of circuitry to process and transmit information. Among these are local circuit neurons (LCNs), a class of neurons that form local circuits within […]
CORTEX
Definition and General Anatomy The term Cortex, derived from the Latin meaning “bark,” “rind,” or “shell,” refers generally to the exterior or superficial layer of an organ or anatomical structure, distinguishing it sharply from the internal core, often referred to as the medulla. This distinction is fundamental across mammalian anatomy, establishing a clear boundary where […]
MESOSTRIATAL SYSTEM
The Mesostriatal System: Neural Basis of Movement and Reward The Core Definition of the Mesostriatal System The mesostriatal system is a critical set of neural pathways within the central nervous system, primarily defined by its dense connections originating in the brainstem and projecting into the Basal Ganglia, a deep group of subcortical nuclei. At its […]
