Cortical control of motor functions

 

The cortex has two main functions

1.                      Recognition

2.                      Performance

 

Recognition is a sensory phenomenon while performance is a motor phenomenon

  • Inability to recognize is called agnosia

  • Inability to perform is called apraxia.

There are several examples of apraxia and agnosia in life. We have the expressive aphasia which is a form of apraxia. Receptive aphasia is a form of agnosia
