Exam 2 Terms and Names To Know Flashcards
(116 cards)
the extended fiber of a neuron through which nerve impulses travel from the soma to the terminal buttons.
Axon
neuron that carries messages away from the central nervous system toward the muscles and glands.
Motor neuron
pioneered the use of electrical stimulation to probe structures deep in the brain.
Walter Hess
the part of the nervous system composed of the spinal and cranial nerves that connect the body’s sensory receptors to the CNS and the CNS to the muscles and glands.
Peripheral nervous system (PNS)
the subdivision of the autonomic nervous system that deals with emergency response and the mobilization of energy.
Sympathetic division
the region of the brain attached to the brain stem that controls motor coordination, posture, and balance as well as the ability to learn control of body movements.
Cerebellum
region of the brain located above the lateral fissure and in front of the central sulcus; involved in motor control and cognitive activities.
Frontal lobe
the biological transmission of traits from parents to offspring
Heredity
the global capacity to profit from experience and to go beyond given information about the environment.
Intelligence
behavioral style; emotional style; response to environment; strongly related to personality.
Temperament
type of intelligence defined as the abilities to perceive, appraise, and express emotions accurately and appropriately, to use emotions to facilitate thinking, to understand and analyze emotions, to use emotional knowledge effectively, and to regulate one’s emotions to promote both emotional and intellectual growth.
Emotional intelligence
the mass of nerve fibers connecting the two hemispheres of the cerebrum.
Corpus callosum
the nerve impulse activated in a neuron that travels down the axon and causes neurotransmitters to be released into a synapse.
Action potential
a recording of the electrical activity of the brain.
EEG
Darwin’s theory that favorable adaptations to features of the environment allow some members of a species to reproduce more successfully than others.
Natural selection
injury to or destruction of brain tissue.
Lesion
the region of the parietal lobes that processes sensory input from various body areas.
Somatosensory cortex
adapted Binet’s test questions for US schoolchildren and standardized the administration of the test, and he developed age-level norms by giving the test to thousands of children.
Lewis Terman
information entering a neuron that signals it to fire.
Excitatory input
this hemisphere generally deals with activities of making judgments about spatial relationships and facial expressions.
Right hemisphere
developed the eight dimensions of temperament: sensory threshold, distractibility vs. persistence, rhythmicity or regularity, activity level, approach vs. withdrawal, adaptability (long-term), positive vs. negative mood, and intensity.
Thomas and Chess
further stimulation, no matter how intense, cannot cause another action potential to be generated.
Absolute refractory period
electrical level the cell must reach before firing—causes a dramatic change in electrical activity
Threshold
region of the brain found below the lateral fissure; contains auditory cortex.
Temporal lobe
