Neuroscoence 2 Flashcards
Structural plasticity
The brains ability to change it’s physical structure in response to learning, active practice, or environmental influences
Neurogenesis
Development of new neurons
Hindbrain
Base of brain that contains several structures that regulate basic life functions
Medulla
A hindbrain structure that controls vital life functions such as breathing and circulation
Contra lateral organization
One side of brain controls opposite side of body.
Pons
Connects medulla to two sides of cerebellum
Helps Coordinate and integrate movements on each side of the body
Cerebellum
A large twosided hindbrain structure at the back of brain
Responsible for muscle coordination and maintaining posture and equilibrium
Reticular formation
Network of nerve fibers located in the center of the medulla that helps regulate attention, arousal, and sleep
Called the reticular activating system
Forebrain
Largest and most complex brain region which contains centers for complex behaviors and mental processes
Also called cerebrum
Substantia nigra
Area of midbrain that is involved in motor control and contains a large concentration of dopamine-producing neuron’s
Cerebral cortex
The wrinkled outer portion of the forebrain which contains the most sophisticated brain centers
Corpus callosum
Think band of axioms that connect the two cerebral hemispheres and acts as a communication link between them
Temporal lobe
Area on each hemisphere of the cerebral cortex, near the temples, that is the primary receiving area for auditory info
Occipital lobe
Area at back of each hemisphere that is primary receiving area for visual info
Parietal lobe
Area on each hemisphere located above temporal lobe that processes somatic sensations . Touch, temp, pressure, info from muscles and joints
