- - - - Readies boy for vigorous activity
      - Flight or fight syndrome
    - - Activities related to protections, nourishment and growth of body
- - - - information about the consequence of an action goes back to source of action so adjustment can be made
- - - - directing attention to important stimuli
    - - ontrolls finely coordinated movements
      - strong memories about movement
      - impulse control, emotion, language, timing
    - - collection of cells that resembles a net
      - arousal and attention
    - - older structure
      - control blood pressure, heart rate, breathing
  - - - black substance
      - connected to stratium- smooth beginning of movement
  - - - amygdala, hippocampus, hypothalamus, septum, cerebral cortex
    - - outer bark
      - anatomical areas
        
        frontal
        
        temporal
        
        parietal
        
        occipital lobe
      - ridges:gyri, valleys: sulci/ fissures
      - functional areas
        
        association cortex
        
        receive information from more than one sense/ combine sensory and motor information to perform complex task
        
        Broca's aphasia
        
        difficulty speaking, grammatically incorrect
        
        Wernicke's area
        
        disrupt ability to understand/ speak understandably
        
        prefrontal cortex
        
        conscious control of thoughts and actions
        
        sarcasm
        
        motor
        
        frontal lobe
        
        voluntary movements
        
        motor humunculus- like the sensory
        
        involved with 'sleepy reach for coffepot"
        
        sensory
        
        somato sensory
        
        parietal lobe
        
        visual
        
        occipital lobe
        
        auditory
        
        temporal
        
        sensory homunculus
        
        little man
        
        skin location and brain
        
        amount of sensory cortex that responds- changed by experience
        
        Wernicke's and Broca's area
        
        only on left side: interpretation and production of speech
    - - bundle of nerve fibres- connect left and right brain
    - - connects to and form autonomic nervous system
      - regulates hunger, thirst, sex drive
      - superchiasmatic nuclei
        
        24-hour clock
    - - coordinate smooth initiation of movement with substantia nigra
    - - relays pain signals
      - signals form eyes and sensory organs
      - process and make sense of information
    - - fear and rewards learning
    - - formation of new memories
      - anterograde amnesia- cannot form new memories
      - associated with dementia
