Brain Flashcards
Phineas Gage
Had a rod go through his skull
Was fairly normal but his personality was drastically different — he became mean and “no longer Gage”
Showcases how function is localized in the brain and how biological factors affect psychological factors
Old Brain
In center of brain
Connected to brain stem
Includes:
Pons, thalamus, medulla, cerebellum, brain stem, and reticular formation
Pons
Helps coordinate serval automatic functions such as movement and posture
Thalamus
Take in sensory information related to seeing, hearing, touching, and tasting
Brain stem
Most ancient and central core of brain
Medulla
Old brain functions that automatically happen (breathing, beating of heart)
Reticular formation
Essential for arousal (sweeping, walking, pain perception)
Cerebellum
Controls voluntary motor skills and speech
Lymbic System
Hypothalamus
Amygdala
Hippocampus
Hypothalamus
Regulates body temperature, circadian rhythms, hunger, and helps govern endocrine system
—regulates pituitary gland
Amygdala
Two Lima-bean sized clusters of neurons involved in memory consolidation and emotion
Hippocampus
Central to learning and memory
Corpus Callosum
Splits the brain and connects the two hemispheres
Cerebral Cortex
Frontal, parietal, temporal, and occipital lobes
Glial Cells
Surrounds neurons and provide support and insulation for them
Frontal Lobes
Speaking Planning Judging Abstract thinking Personality aspects
Parietal Lobes
Sense of touch
Body position
Occipital
Sights
Temporal Lobes
Sounds
Motor Cortex
Controls voluntary movements
Sends messages to muscles as to what to do
Somatosensory Cortex
Processes incoming sensations
Association Areas
Connects sensory and motor areas
Deal with subtle processes
Prevail throughout all four lobes
