Unit 3 (Neurotransmitters (Dopamine: Movement, learning, attention, and…

- - - - Wernicke's Area = comprehension of language. Damage = fluent aphasia (word salad); ability to speak, but lack of meaning (left hemisphere in most people)
      - Auditory cortex: info from the right lear goes to the left auditory cortex and vice versa
    - - Motor cortex: controls voluntary movements. More space in motor cortex is dedicated to parts with more dexterity, like hands
      - Prefrontal cortex: linked to planning ahead.
      - Linked to personality (think Phineas Gage)
      - Broca's Area: ability to speak. Damage = non-fluent aphasia (able to understand language, but unable/difficult to speak (left hemisphere in most people)
    - - Visual cortex: enables and processes sight.
    - - Somatosensory cortex: interpretation of touch. More of the somatosensory cortex is devoted to more sensitive areas, like fingers and lips.
- - - - Sympathetic NS = arousing (pupils dilate, heartbeat accelerates, digestion slows, secretion of (nor)epinephrine, etc.
      - Parasympathetic NS = calming (contracted pupils, slowed heartbeat, stimulates digestion, stimulates gallbladder, contracts bladder, etc.)
- - - - Made by glial cells ("worker bees" ; nourish and support nerve cells)
      - Degeneration of myelin sheath-->multiple sclerosis (MS)
