Unit 3 - Brain Cheat Sheet Quiz Flashcards
sensory switch board, processes every sense other than smell
Thalamus
controls heartbeat and breathing
Medulla
oldest part of the brain, newer parts are built on top of this,
automatic survival functions
Brainstem
controls arousal
Reticular Formation
Processes coordinates voluntary movement and balance
Cerebellum
fear and aggression
Amygdala
learning and memory
Hippocampus
reward center, hunger, thirst, sexual arousal
Hypothalamus
Master gland, works with hypothalamus
Pituitary Gland
Outside of the brain, control an information-processing center of the brain
Cerebral Cortex
beefy portion of brain
Cerebrum
higher order thinking (what makes us human)
Frontal
receives sensory input for touch/body position
Parietal
receives visual information
Occipital
receives auditory information
Temporal Lobe
left hemisphere section controls movement of the right side of the body and right hemisphere section controls movement of left side of the
body
Motor Cortex
area at front of parietal lobe that registers and processes the
senses
Sensory Cortex
not included in primary motor or sensory function, but
involved in higher mental functions
Association Areas
Language comprehension
Wernicke’s Area
controls speech
Broca’s Area
brains ability to reorganize itself, higher in younger people to
overcompensate for damage
Plasticity
connects left and right brain hemispheres
- Not on the top of the brain
- Hemispheres are not connected until you get down to the corpus callosum in middle of brain
- You might have your corpus callosum severed because you get frequent seizures (epilepsy)
Corpus Callosum
- Right side/Right visual field -> left hemisphere
- Left Side/Left Visual Field -> Right hemisphere
Opposite hemispheres control opposite sides of the body
- Analytical thoughts
- Math/Science
- Language/Speech
- Controls more important functions than right hemisphere
Left Hemisphere
- Emotion
- Artsy
Right Hemisphere
Function: enables muscle action, learning, and memory
Malfunctions: ACh neurons deteriorate with Alzheimers
Acetylcholine
Function: Influences movement, learning, attention, and emotion.
Malfunction: Oversupply linked to schizophrenia. Under supply linked to tremors and Parkinson’s disease
Dopamine
Function: Affects mood, hunger, sleep, and arousal.
Malfunction: Under supply linked to depression.
Seretonin
Function: Helps control alertness and arousal
Malfunction: Under supply can depress mood
Norepinephrine
