PSYC1020 Lecture Notes - Lecture 5: Amyotrophic Lateral Sclerosis, Autonomic Nervous System, Cerebral Cortex
PSYC1020: Brainstem and Cerebellum
• Medulla
➢ Autonomic nervous system functions
➢ Controls heart rate, respiration, regulation of blood pressure, body
temperature
➢ Reflex centres for coughing, sneezing, swallowing and vomiting.
• Pons
➢ Relays signals from cerebral cortex to cerebellum
➢ Some nerves to the face for some facial expressions and eye movements
➢ Note: we do not know much about the pons.
• Disorders of consciousness:
PERSISTENT VEGETATIVE STATE:
➢ Severe damage to the upper brain (hemispheres and cortex).
➢ If the brainstem is not damaged, the autonomic nervous system functions can
remain.
➢ Sometimes normal respiration, control of heart rate, some face and eye movements
remain
➢ No conscious awareness.
LOCKED-IN SYND‘OME
➢ Amyotrophic lateral sclerosis (ALS)
➢ A.K.A Motor Neurone Disease
➢ Loss of motor neurones to the spinal chord
➢ Or brain injury following accident
➢ Itat ereellu ad raiste, ut disoeted fro spinal chord
➢ Normal cognitive function (vision etc.)
