Mods 12-13 Flashcards
Brainstem
Controls automatic survival functions
Medulla
controls heartbeat and breathing
Thalamus
directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
Reticular Formation
controls alertness and arousal
Cerebellum
Sensory input, coordinating movement, output balance, enables learning/memory
Limbic System
neural system located below the cerebral hemispheres; associated with emotions and drives
Amygdala
Controls emotions
Hypothalamus
Directs Maintenance activities, helps govern endocrine System, linked to reward
Hippocampus
Stores memories
Cerebral cortex
The intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body’s ultimate control and information-processing center.
Frontal lobes
speaking, muscle movements, making plans and judgements
Parietal lobes
Receives sensory input for touch and body
Occipital lobes
receive information from the visual fields
Temporal lobes
Receive sensory input about sound
Motor cortex
Controls voluntary movements
Somatosensory cortex
registers and processes body touch and movement sensations
Association Areas
involved in higher mental functions such as learning, remembering, thinking and speaking.
Plastcity
the brain’s ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience
Neurogensis
the formation of new neurons
Corpus callosum
The large band of neural fibers connecting the two brain hemispheres and carrying messages between them
Split Brain
a condition resulting from surgery that isolates the brain’s two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them
Consciousness
our awareness of ourselves and our environment
Cognitive Neuroscience
the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language)
Dual Processing
principle that info is often simultaneously processed on separate conscious and unconscious tracks
Blindsight
a condition in which a person can respond to a visual stimulus without consciously experiencing it
Parallel Processing
Processing many aspects of a problem simultaneously; generally used to process WELL LEARNED info or to solve EASY problems
Sequential Processing
Processing one aspect of a problem at a time; generally used to process NEW info or to solve DIFFICULT problems
Paul Broca
Identified Broca’s areas, which is involved in expressive language (frontal lobe)
Carl Wernicke
Discovered wernickes area involved in receptive language (temporal lobe)
Roger Sperry, Micheal Gazzaniga
First split brain surgeries on human
Charles Darwin
Natural Selection
Phineas Gage
Tamping iron accident damaged neural tracks in his frontal lobe
