Physiological functions of Cerebral cortex

PHYSIOLOGICAL FUNCTIONS OF CEREBRAL CORTEX 

  • Centre for voluntary movements-exerted by primary motor cortex Viz. Excitomotor cortex and is also responsible for highly skilled movements.
  • Centre for quick and phasic movements
  • Centre for postural maintenance-exerted by supplementary motor area
  • Centre for stretch and postural maintenance
  • Centre for major motor control-mediated by pyramidal and extra pyramidal tracts
  • Centre for complex co-ordinated movements
  • Frontal eye field of cerebral cortex is concerned with eye movement, pupillary dilatation and tear secretion
  • Centre for reflex vocalization
  • Centre for learning, memory processing and memory storage-compares past experiances and interprets the present experience
  • Centre for mood, emotions and behaviour-like socializing
  • Centre to receive specific sensations-crude sensations have sub cortical destination(except pain and crude temperature perceptions at thalamus level itself) finer sensations of touch temperature joint and vibratory senses are relayed to cortex
  • Centre for discriminative ability
  • Centre for spatial recognition
  • Centre for tactile discrimination and localization
  • Centre to compare and recognise relative intensity of different stimuli
  • Centre to recognise similarity and differences stereognosis
  • Centre for gustation-lower end of somestheti c cortex, lie next to motor cortex governing muscles of mastication
  • Centre for visual senses and visuo-psychic sensations
  • Centre for auditory senses and audito-psychic sensations
  • Centre for olfactory sensations
