Chapter 2 part 2 Flashcards
neuropsychology and brain imaging
the brain is part of which nervous system
central nervous system
what are the major divisions of the brain?
hindbrain, midbrain, and forebrain
what parts of the brain are in the hindbrain?
medulla, cerebellum, and pons
what happens if you damage your hindbrain?
you will die or be in a coma for the rest of your life
where is the hindbrain located?
at the stem of the brain / underside of the brain (think of the stem of the flower)
what does the medulla control?
critical bodily functions, like heartbeat, gag reflex, and swallowing
where is the medulla located
in the hindbrain, it is the first part of the hindbrain, where the brain emerges from the spinal cord, where the brain begins
what inhibits the medulla?
alcohol and opiates
where is the cerebellum located?
in the hindbrain, looks like a cauliflower or a mini-brain, loosely connected to brain
what does the cerebellum control?
walking an balance, anything we do over and over again for a long time, like driving
how does the cerebellum work?
after doing a task over and over again, the cerebellum will take that task over to free up space in the brain (walking while chewing gum), when the task feels like 2nd nature, the cerebellum has taken it over
where is the midbrain located?
on top of the hindbrain (the yellow center that sits on top of the stem of the flower)
what parts of the brain are in the midbrain?
tectum, tegmentum, and reticular formation
what is the midbrain’s main focus?
has a lot to do with vision, you need it for your eyes to work properly
what are the tectum and tegmentum in charge of?
visual reflexes, eyes focusing, constricting and enlarging pupils, regulating light, and orienting you toward something that moved in the corner of your vision
what happens if your pupils don’t constrict when you shine a bright light into them?
you have midbrain damage
where is the reticular formation located?
it runs from the pons to the midbrain
what is the reticular formation responsible for?
arousal (for being awake)
