Dissociatives inhibit the normal functioning NMDA receptors by binding to and blocking them. This disruption of neural network activity leads to loss of normal cognitive and affective processing, psychomotor functioning, anesthesia and eventually the equivalent of a "k-hole". | Dissociatives inhibit the normal functioning NMDA receptors by binding to and blocking them.
