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. ^{1Contributions of anterior cingulate cortex to behaviour1995 · Brain}

Morphology

The ACC contains diverse neuronal populations:

Pyramidal neurons (Layers II-III, V-VI): Projection neurons with extensive apical dendrites
GABAergic interneurons: Parvalbumin+, Somatostatin+, VIP+ subtypes
Burst-firing neurons: Layer V projection neurons
von Economo neurons (VENs): Large pyramidal neurons in Layer V (primates)

Molecular Markers

CaMKIIα - excitatory pyramidal neurons
GAD67 (GABA) - inhibitory interneurons
Parvalbumin (PV) - fast-spiking interneurons
Somatostatin (SST) - dendritic-targeting interneurons
VIP - disinhibitory interneurons

Normal Function

The ACC orchestrates:

Cognitive Control: Error detection, conflict monitoring, decision-making
Emotional Processing: Affective dimension of pain, empathy
Pain Perception: Affective-motivational pain component
Executive 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 processing
Depression: ACC hyperactivity in rumination
Chronic Pain: ACC central sensitization
OCD: ACC hyperconnectivity
