Modules 11 and 12: The Brain Flashcards
EEG
amplified recording of brain waves and electrical activity
MEG
measures the brain’s natural electrical activity, maps brain functions as well as epileptic seizures
CT
x-ray of the brain, indentifies TBIs
PET
tracks where a temporarily radioactive form of glucose goes while the brain performs an activity
MRI
map of the brain’s structure
fMRI
shows blood flow and brain activity (functional mri)
Medulla
Base of the brainstem. controls heartbeat and breathing
pons
above the medulla. coordinates movement and sleep
thalamus
top of the brain stem. brain’s sensory control center, receives information from all senses except smell and reroutes it to higher brain structures
reticular formation
neuron network extending from the spinal cord right up through the thalamus, filters incoming stimuli and controls arousal
cerebellum
enables nonverbal learning and skill memory
Limbic system
center to controlling emotions and drives, consists of the hypothalamus, the amygdala, and the hippocampus
amygdala
emotional and survival responses, “fight or flight”
hypothalamus
maintains homeostasis
hippocampus
processes conscious, explicit memories
cerebral cortex
brain’s main processing center, controls four different lobes
frontal lobe
involved in speaking, muslce movements, and in making plans and judgements
parietal lobe
top of the head, receives sensory input and body position
occipital lobe
involved with seeing, processes visual cues
temporal lobe
involved in hearing, processes sounds
Motor cortext
involved in “motor” movements
somatosensory cortex
area that registers and processes body touch and movement sensations
auditory cortex
located just above the temporal lobes, sound is processed fully
visual cortex
located in occipital lobes, processes visuals and sends info teh identify what they are
association areas
most of the brain’s thinking, remembering, and learnign
Broca’s Area
expressive language
wernickes area
receptive language
plasticity
brain’s ability to change via reorganizing after damage or building new pathways built on experience
neurogenesis
producing new neurons, brain’s attempt to self repair by reorganizing existing tissue or mend itself.
