Chapter 1: Biology and Behavior Flashcards
Contribution to neuropsychology: Franz Gall
Developed the doctrine of phrenology; the part of the brain associated with traits expands, causing bulges on the head. Intellect can be linked to anatomy
Contribution to neuropsychology: Pierre Flourens
Extirpation on rabbits and pigeons; surgically removing parts of the brain and observing behavioral responses
Contribution to neuropsychology: William James
Father of American Psychology. Functionalism, system of though in psychology that studies how mental processes help individuals to adapt to their environment.
Contribution to neuropsychology: John Dewey
Functionalism, but with the organism as a whole and how it adapts to its environment
Contribution to neuropsychology: Paul Broca
Language=left side of the brain
Contribution to neuropsychology: Hermann von Helmholtz
measured the speed of a nerve impulse
Contribution to neuropsychology: Sir Charles Sherrington
first inferred the existence of synapses but thought that transmission was electrical. It is a chemical process
What parts of the NS are in the CNS?
Brain and spinal cord
What parts of NS are in the PNS
nervous tissue, 31 pairs of spinal nerves and 12 pairs of cranial nerves outside the brain and spinal cord. Olfactory and optic nerves.
What do afferent neurons do?
sensory neurons: transmit sensory info from receptors to the spinal cord and brain
What do efferent neurons do?
Motor neurons: transmit motor information from the brain and spinal cord to the muscles and glands
What functions are accomplished by the sympathetic nervous system?
Activated by stress. Fight or flight response. Increases HR, redistributes blood to the muscles of locomotion, increases blood glucose concentration, relaxes the bronchi, decreases digestion and peristalsis, dilates the eyes to maximize light intake, and releases epinephrine into the bloodstream.
What functions are accomplished by the parasympathetic nervous system?
Conserve energy. resting and sleeping states. Reduces HR and constricts the bronchi. Manages digestion by increasing peristalsis and exocrine secretions. Acetylcholine is the neurotransmitter responsible for parasympathetic response in the body.
Function? Cerebral Cortex
Complex perceptual, cognitive and behavioral processes
Function: Basal ganglia
