<p>The anterior cingulate cortex is a collar of white matter that surrounds the corpus callosum (the bundle of fibers that connects the hemispheres of the brain. This is a major network hub of the brain, responsible for the integration of network activity of all sorts.&nbsp; The anterior cingulate cortex is responsible for much of our autonomic functioning, including heart rate, decision making, empathy, impulse control and emotion.&nbsp;&nbsp;</p><p>Mood Disorders are often seen stemming from a dysregulation in this area and can manifest as depression, amotivational, and angry behaviors. The ACC can also be disorganized if one was predispositioned towards developmental trauma.</p><p>Studies on meditators of various disciplines (notably transcendental meditation) show the anterior cingulate gyrus as activated by alpha when in deep states.&nbsp; This has been linked to a surge in dopamine, in honing of attention (and expertise in attention), and in the ability to self-regulate easily.&nbsp; The ACC is disorganized in developmental trauma. Hyperreactivity of the anterior cingulate is also the brain signature of OCD (also in substance abuse).</p><p><br></p>
