forebrain

• forebrain


  largest part of brain
• forebrain location

  starts above the midbrain and extends to top of brain
• neural pathways

  connect structures in the mid and hind brain to coordinate brain activity
• forebrain regulates

  cognitive processes:

  • thinking
  • learning
  • processing
  • memory
  • emotion
• hypothalamus

  primary function is homeostasis
• homeostasis


  maintain stable internal environment
• hypothalamus

  connected to the endocrine system so when stressed sympathetic nervous system is activated
• hypothalamus controls

  • body clock
  • regulates thirst
  • body temperature
• damage to hypothalamus

  • body temperature disruption
  • water retention or dehydration
• thalamus


  relays sensory and motor signals to the cerebral cortex
• thalamus regulates

  • consciousness
  • sleep
  • alertness
• damage to thalamus

  • deafness
  • sensory issues
  • blindness
• cerebrum

  two large hemispheres that.cover up the upper part of brain
• cerebrum regulates

  • conscious actions
  • cerebral cortex
  • voluntary movement
  • emotions
  • personality
• cerebral cortex

  • a 3mm thick, outer layer of the brain
  • covers most of brain surface
• cerebral cortex

  contains majority of neurone from the nervous system
• cerebral cortex has a wrinkled layer made up of

  • bulges (gyri)
  • sorrows (sulci)
• cerebral cortex - increased area


  increased number of neutrons and neural connections
• cerebral cortex regulates

  • perception
  • learning and memory
  • language
