In the human brain, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24, 32, and 33.

What is agenesis of the corpus callosum? Agenesis of the corpus callosum (ACC) is a congenital condition (present at birth) where you’re missing or partially missing the corpus callosum. This is a thick bundle of nerve fibers that connect the right and left hemispheres (sides) of your brain.

2011年4月1日 · The anterior cingulate cortex (ACC) lies in a unique position in the brain, with connections to both the “emotional” limbic system and the “cognitive” prefrontal cortex.

2022年8月9日 · The anterior cingulate cortex (ACC) is part of the cerebral cortex and envelopes the corpus callosum. The ACC is involved in high-level cognitive functions like decision-making and problem solving, and psychological functions relating to social interaction, emotion, and empathic responses.

2021年6月7日 · The anterior cingulate cortex (ACC) is a region of the human brain (Brodmann area 24, 33, and 34) located at the cingulate cortex’s most frontal part. The ACC wraps around the corpus callosum, a bundle of nerve fibers found beneath the cerebral cortex, and is located before the posterior cingulate cortex (PCC), which is adjacent to the ...

2009年12月31日 · The anterior cingulate cortex (ACC) is an integration center that interconnects neurons from the frontal cortex, the thalamus and the amygdala, processing cognitive, emotional and autonomic functions (Shackman et al., 2011; Vogt, 2005). Importantly, the ACC is strongly implicated in the pathophysiology of depression as well as in pain processing.

The anterior cingulate cortex (ACC) is implicated in a broad range of behaviors and cognitive processes, but it has been unclear what contribution, if any, the ACC makes to social behavior. We argue that anatomical and functional evidence suggests ...

2024年7月17日 · Here, we tracked ACC activity in male mice performing go/no-go auditory discrimination tasks with manipulated stimulus-reward contingencies. Individual ACC neurons integrate the outcome...

4 天之前 · Further analysis revealed that ACC neurons projecting to the periaqueductal gray (PAG), a brain region involved in fear and pain regulation, selectively conveyed emotional pain information.

3 天之前 · The scientists further demonstrated that signals from the ACC to the brain’s periaqueductal gray (PAG) region are crucial for transforming empathy into behavioral responses, like freezing or avoidance. Manipulating this ACC-to-PAG pathway directly affected empathic behaviors, confirming its vital role in translating observed pain into ...
