Chapter 2 Part Two Flashcards
Brain Stem
Oldest part of the brain
Automatic and survival functions
Medulla
Just above the brain stem
Controls breathing and heartbeat
Reticular formation
Controls arousal/alertness
Thalamus
Sensory switchboard
Hippocampus
Neural center in the limbic system
Storage and memory
Pons
Controls sleeping and dreaming(REM)
Cerebellum
Processes sensory inputs and coordinates movement and balance
Limbic system
Border of brain stem and cerebral hemisphere
Amygdala
Part of the limbic center controlling emotions of fear and aggression
Hypothalamus
Regulates hunger, thirst, body temp - reward centers
Cerebral cortex
Back of the brain
Glial cells
Guide neural connections and provides nutrients
Frontal lobes
Lobes involved in speaking and muscle movements, planning, and judgement
Occipital lobes
Contain visual cortex
Parietal lobes
Contains sensory cortex
Temporal lobes
Contains auditory areas
Motor cortex
Controls voluntary movements
Sensory cortex
In front of parietal lobes - behind motor cortex
Registers body touch and processes
Association Areas
Connects sensory and motor areas
Thought to be concerned with higher mental activities
Phineas Gage
Railroad construction man with severe accident
Had aphasia
Aphasia
Important part of language as a result to damage to several cortical areas - Broca’s and Weirnickes
Broca’s area
Located in left frontal lobe
Controlling motor ability to produce speech
Weirnickes area
Located in left temporal lobe
Involved in language comprehension and expression
Plasticity
Brains capacity for modification after damage to certain parts
