The anterior cingulate cortex (ACC) pyramidal neurons are layer 2/3 and layer 5 glutamatergic neurons in the ACC, a critical node in the salience network and emotion regulation circuits. These neurons play essential roles in cognitive control, pain perception, decision-making, and emotional processing. 2Motivation of extended behaviors by anterior cingulate cortexOpen reference

-
Pain Processing: Emotional and affective dimensions of pain
-
Emotion Regulation: Processing of negative emotions, fear, and anxiety

Decision Making: Value-based choices, reward prediction error signaling
-
Social Cognition: Theory of mind, empathy, social pain
ACC pyramidal neurons project to:
-
Prefrontal cortex (dorsolateral and ventromedial)

Vulnerability in Disease
Alzheimer’s Disease
ACC is among the early regions showing amyloid deposition and hypometabolism in AD. ACC pyramidal neurons exhibit:
-
Early tau pathology spreading from entorhinal cortex
-
Hypometabolism detectable via PET even before clinical symptoms
-
Dysfunctional connectivity in the salience network
-
Accumulation of p-tau in dendrites and soma
Parkinson’s Disease
-
ACC shows reduced dopamine innervation in PD
-
Impaired error prediction signaling
-
Connection to non-motor symptoms including depression and anxiety
Frontotemporal Dementia
-
ACC degeneration is prominent in behavioral variant FTD
-
Layer 5 pyramidal neuron loss
-
Early disruption of salience network connectivity
Other Conditions
-
Depression: ACC hypermetabolism, altered glutamatergic signaling

Background
The study of Anterior Cingulate Cortex (Acc) Pyramidal Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
Research Evidence
Dynamic functional connectivity measures are more reliable than stationary connectivity measures in attention networks
Dorsal attention network (DAN) Factor 3 (anterior DAN) obtained at rest significantly predicts alerting effect on Attention Network Test in both sessions (p=0.001 and p=0.037)
Fronto-parietal task control network (FPTC) Factor 3 predicts orienting effect at Session 1 (p=0.010)
The relationship between DAN Factor 3 and alerting effect was present during both rest and task conditions
Changes in dynamic connectivity factor scores between sessions correlated with changes in accuracy in Incongruent Flanker trials
Higher dynamic connectivity (factor scores) was associated with larger alerting and orienting effects, possibly reflecting more effortful processing or rigidity in resource reallocation
No significant group differences in ICA-defined resting networks between PD and controls, suggesting subtle differences in early-stage PD
Dynamic connectivity factor structures are stable across rest and task states (Procrustes congruence 0.89-0.93 for DAN)
Individual differences in dynamic connectivity are reliable across scanner sessions but not invariant, and changes reflect behavioral changes
Attention Network Test (ANT) behavioral performance measurement
PD participants showed slowed response latencies across all conditions. PD participants had significantly larger alerting effect (No Cue - Center Cue) compared to controls (PD: 47ms vs Controls: 28ms, p=0.025). No significant differences in orienting or executive effects between groups.
Model System: Human participants: 25 Parkinson disease (PD) patients and 21 healthy controls (ages 41-86)
Statistical Significance: p = 0.025 for alerting effect difference between groups
ICA analysis of resting-state networks
Identified dorsal attention network (DAN), salience network, and default mode network (DMN). No significant group differences found between PD and controls in these networks.
Model System: Human participants: 25 PD patients and 21 controls undergoing resting-state fMRI
Statistical Significance: No significant group differences (p > 0.05 after correction)
Dynamic connectivity factor analysis
Extracted 4 factors for each network (DAN, FPTC, DMN). Factor structures were qualitatively similar to previous aging sample but explained less variance in this sample. Reliability of factor scores was higher than reliability of individual pairwise correlations.
Model System: Human participants: 25 PD and 21 controls during resting-state fMRI scans
Statistical Significance: DAN factor reliability 0.56-0.64, FPTC 0.35-0.69, DMN 0.57-0.78 (all p < 0.01 except FPTC Factor 4 p=0.01)
Reliability comparison: dynamic vs stationary connectivity
Dynamic connectivity measures are more reliable than stationary connectivity measures. Median reliability of factor scores higher than median reliability of pairwise correlations for DAN (p=0.020) and DMN (p=0.036). FPTC showed marginally significant difference (p=0.082).
Model System: Same 46 participants in resting-state fMRI
Statistical Significance: DAN: p=0.020, DMN: p=0.036, FPTC: p=0.082
Prediction of alerting effect from resting-state dynamic connectivity
DAN Factor 3 (anterior DAN) significantly predicted alerting effect magnitude at both sessions (Session 1: p=0.001, R2=0.21; Session 2: p=0.037, R2=0.09). Effect remained significant after controlling for age. Group-by-factor interaction significant at Session 1 (p=0.002) but not Session 2.
Model System: 46 participants (25 PD, 21 controls) from resting-state scans to ANT performance
Statistical Significance: Session 1: t(44)=3.46, p=0.001; Session 2: t(44)=2.15, p=0.037; Group x Factor interaction Session 1: p=0.002
Prediction of orienting effect from resting-state dynamic connectivity
FPTC Factor 3 predicted orienting effect at Session 1 (p=0.010) but not Session 2 (p=0.116). No significant group or group-by-factor interaction.
Model System: 46 participants from resting-state scans to ANT orienting effect
Statistical Significance: Session 1: t(44)=2.70, p=0.010; Session 2: t(44)=1.6, p=0.116
Task-based dynamic connectivity analysis
DAN factor structure during task highly congruent with rest (Procrustes correlation 0.93 Session 1, 0.89 Session 2, p=0.001). DAN Factor 3 during tasks predicted alerting effect (Session 1: p=0.023, R2=0.11; Session 2: p=0.107). During tasks, DAN Factor 3 also negatively predicted orienting effect at Session 2 (p=0.013).
Model System: 46 participants during ANT task fMRI runs
Statistical Significance: DAN Factor 3: Session 1 p=0.023, Session 2 p=0.107; Orienting: Session 2 p=0.013
Change in dynamic connectivity predicting behavioral change
Increase in DAN Factor 3 between sessions correlated with improvement in accuracy in Incongruent Flanker condition (r=0.37, p=0.011). Increase in FPTC Factor 3 correlated with improvement in Incongruent (r=0.39, p=0.007) and Center Cue conditions (r=0.32, p=0.027).
Model System: Longitudinal: Session 1 to Session 2 change in same 46 participants
Statistical Significance: DAN Factor 3: r(44)=0.37, p=0.011; FPTC Factor 3 Incongruent: r(44)=0.39, p=0.007; FPTC Factor 3 Center Cue: r(44)=0.32, p=0.027
