LCT7: Brain Structures Flashcards
Hindbrain
basic functions of life
Midbrain
orientation movement
Forebrain
complex functions
Brainstem
basic survival - breathing and heart rate
Cerebellum
“little brain” - balance and movement
Thalamus
- way station or traffic officer
- sensory relay
Hypothalamus
Vital Functions
- hunger, thirst
- reproduction
- body temperature
- hormone release (w/pituitary)
Limbic System
grouping of subcortical structures between higher and lower parts of the brain (includes: amygdala, hippocampus) - involved in emotional reactions and motivated behavior
Amygdala
arousal and regulation of emotion
Hippocampus
memory: formation and recall of memories (“sea horse” shape)
Basal Ganglia
coordination of voluntary movement
Cortex
outer surface of the brain
Cerebral Cortex
divided into halves –> connected by corpus callosum
Occipital Lobe
primary visual cortex
Parietal Lobe
information about touch and somatosensory cortex
Temporal Lobe
hearing and language
Frontal Lobe
motor, speech production, planning (also executive functions: abstract thinking, judgement, reasoning, “higher-order thinking”)
Recovery from brain damage depends on…
- age of the individual
- extent of the damage
Repairing the damaged brain depends on…
- substitution of function
- neurogenesis
- brain tissue grafts (stem cells)
