Anterior Cingulate Cortex (ACC) Neurons
Introduction <table class="infobox infobox-cell">Category </td>Brain Region </td>Neurotransmitter </td>Species </td>
Anterior Cingulate Cortex (Acc) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The Anterior Cingulate Cortex (ACC) is a key prefrontal region involved in executive control, emotion regulation, decision-making, and pain processing. [@devinsky1995]
Overview

Morphology The ACC contains diverse neuronal populations:
Pyramidal neurons (Layers II-III, V-VI): Projection neurons with extensive apical dendritesGABAergic interneurons : Parvalbumin+, Somatostatin+, VIP+ subtypesBurst-firing neurons : Layer V projection neuronsvon Economo neurons (VENs) : Large pyramidal neurons in Layer V (primates)Molecular Markers
CaMKIIα - excitatory pyramidal neuronsGAD67 (GABA) - inhibitory interneuronsParvalbumin (PV) - fast-spiking interneuronsSomatostatin (SST) - dendritic-targeting interneuronsVIP - disinhibitory interneuronsNormal Function The ACC orchestrates:
Cognitive Control : Error detection, conflict monitoring, decision-makingEmotional Processing : Affective dimension of pain, empathyPain Perception : Affective-motivational pain componentExecutive Function : Goal-directed behavior, working memory
Disease Vulnerability
Alzheimer's Disease (AD)
ACC shows early hypometabolism and amyloid deposition
Executive dysfunction correlates with ACC atrophy
Altered pain perception in AD
VENs vulnerable in early AD
Parkinson's Disease (PD)
Executive deficits involving ACC dysfunction
Impulse control disorders associated with ACC changes
Depression in PD involves ACC abnormalities
Pain processing altered in PD
Frontotemporal Dementia (FTD)
ACC atrophy prominent in behavioral variant FTD
Loss of VENs in FTD
Emotional disinhibition
Impaired social cognition
Other Disorders
Schizophrenia : ACC dysfunction in error processingDepression : ACC hyperactivity in ruminationChronic Pain : ACC central sensitizationOCD : ACC hyperconnectivityLayer-Specific Functions
