Anterior cingulate cortex (ACC): the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum; plays a role in a wide variety of autonomic functions such as regulating blood pressure and heart rate; also involved in rational cognitive functions, such as reward anticipation, decision-making, empathy, impulse control, emotion

The most basic form of ACC theory states that the ACC is involved with error detection.[4] Evidence has been derived from studies involving ...

Anxious? Activate your anterior cingulate cortex with a little meditation

Scientists, like Buddhist monks and Zen masters, have known for years that meditation can reduce anxiety, but not how. Scientists have now succeeded in identifying the brain functions involved.


Indirect spinothalamic pathways: these pathways mediate the affective and arousal components of pain, temperature, and simple tactile sensations


Pain network: Dorsal anterior cingulate cortex (dACC), insula (Ins), somatosensory cortex (SSC), thalamus (Thal), and ...


Why do some traumatized people get PTSD while others don't?
