Biological Perspective Flashcards
Pons
It’s a bridge from the lower to upper brain.
- It is implicated in the influence of dreams and sleep paralysis
Reticular Formation
Region in pons and medulla (on the back side) that controls the animals ability to selectively attend to certain information.
Cerebellum
Controls balance, fine motor functions, and muscle memory.
Thalamus
Controls the destination of the sensory input
Hypothalamus
Regulates major homeostatic functions: body temperature, thirst, hunger, sleep/wake cycle, and sexual activity.
Hippocampus
Forms long term memory to be stored elsewhere.
Amygdala
Controls and remembers long term/passed fear responses.
Cingulate Cortex
Plays a role in both the emotional and cognitive aspects of mental processing.
Corpus Callosum
Directly under the cingulate cortex and sends signals between the left and right lobes.
Fornix & Mammillary Bodies
Fornix moves signals between amygdala and mammillary bodies which helps remember episodic memories
- Episodic Memory: memory of autobiographical events like times, places, people…
Frontal Lobe
Deals with processing higher cognitive functions like planning, personality, and complex decision making. (Keeps the limbic system in line)
- Motor Cortex: controls the skeletal muscles of the body - Broca's Region: the cortex for formulating grammatical correct words and sentences.
Parietal Lobe
Contains the Somatosensory cortex which interprets mechanical receptor input like temperature, touch, and spacial awarness.
Temporal Lobe
Processes the auditory input received by the ears.
- Wernicke’s Region: interprets written and spoke words. Identifies what they mean.
Occipital Lobe
Processes the visual information received by the eyes.
Broca’s Aphasia
Damage to the region makes formulating the mouth structures for proper speech difficult.
