Body schema is an organism's internal model of its own body, including the position of its limbs. The neurologist Sir Henry Head originally defined it as a postural model of the body that actively organizes and modifies 'the impressions produced by incoming sensory impulses in such a way that the final sensation of body position, or of locality, rises into consciousness charged with a relation ...
Proprioception is occasionally impaired spontaneously, especially when one is tired. Similar effects can be felt during the hypnagogic state of consciousness, during the onset of sleep. One's body may feel too large or too small, or parts of the body may feel distorted in size. Similar effects can sometimes occur during epilepsy or migraine auras.
A longstanding neurological explanation of this effect was that, without incoming signals from proprioceptive neurons, the limb perception system presented to consciousness a default, slightly flexed position, considered to be a universal, inborn "body schema". [21]
One of the most important of these senses is called proprioception, or the sense of position. It's defined as the conscious or unconscious awareness of joint position, and it refers to being able ...
Proprioception refers to the sensory information relayed from muscles, tendons, and skin that allows for the perception of the body in space. This feedback allows for more fine control of movement. In the brain, proprioceptive integration occurs in the somatosensory cortex, and motor commands are generated in the motor cortex.
Sensory processing is the process that organizes and distinguishes sensation (sensory information) from one's own body and the environment, thus making it possible to use the body effectively within the environment
The receptor for the sense of balance resides in the vestibular system in the ear (for the three-dimensional orientation of the head, and by inference, the rest of the body). Balance is also mediated by the kinesthetic reflex fed by proprioception (which senses the relative location of the rest of the body to the head). [22]
The initial conditions of the movement, such as the proprioceptive information of the limbs and body. The response specifications for the motor programs, which are the parameters used in the generalized motor program, such as speed and force.
