Motor control loss can be defined as a suppression of the process by which humans and other animals organize and execute their physical actions. Fundamentally, it is the integration of sensory information (both about the world and the current state of the body) to determine the appropriate set of muscle forces and joint activations to generate some desired movement or action. This process requires cooperative interaction between the central nervous system and the musculoskeletal system, and is thus the result of a combination of information processing, coordination, mechanics, physics, and cognition. Successful motor control is crucial to interacting with the world; it not only determines action capabilities, but regulates balance and stability as well.

In terms of hallucinogenic drugs, although in certain contexts these substances can actually enhance motor control through the component known as increased bodily control, it's worth noting that more often than not they simply decrease it.

The experience of motor control loss ranges between subtle and all-encompassing in its effects as at lower levels it simply results in a general sense of difficulty when performing physical tasks involving dexterity, walking, and balance. At higher levels, however, this component moves beyond subtle in its effects and becomes capable of completely disabling one's ability to use any level of fine or gross motor control. This results in catatonic states and the inability to perform any task beyond lying or sitting down regardless of the person's current cognitive capabilities.
