How to Play
long, thin fiber that transmits signals away from the soma to other neurons or to muscles or glands
segment of the brainstem that lies between the hindbrain and the forebrain; contains an area involved with integrating sensory processes
the major structure that connects the two cerebral hemispheres
reseach method assessing hereditary influence by comparing the resemblance of identical twins and fraternal twins with respect to trait
system made up of all those nerves that lie outside the brain and spinal cord
contains the cell nucleus and much of the chemical machinery common to most cells
largest and most complex region of the brain, encompassing a variety of structures, including the thalamus, hypothalamus, limbic system, and cerebrum
a chemical that mimics that action of a neurotransmitter
a process in which neurotransmitters are sponged up from the synaptic cleft by the presynaptic membrane
a very brief shift in a neuron's electrical charge that travels along an axon
a voltage change at a receptor site on a postsynaptic cell membrane
procedure in which the bundle of fibers that connects the cerebral hemispheres is cut to reduce the severity of epileptic seizures
structure in the forebrain through which all sensory information (except smell) must pass to get to the cerebral cortex
loosely connected network of structures located roughly along the border between the cerebral cortex and deeper subcortical areas
small knobs at the end of an azon that secrete chemicals called neurotransmitters
principle that posits that heritable characteristics that provide a survival or reproductive advantage are more likely than alternative characteristics to be passed on to subsequen
releases a great variety of hormones that fan out within the body, stimulating actions in the other endocrine glands
chemical substances released by the endocrine glands
threadlike strands of DNA molecules that carry genetic information
a junction where information is transmitted from one neuron to another
system consisting of the brain and spinal cord
the convoluted outer layer of the cerebrum
axons that carry information inward to the central nervous system from the periphery of the body
cells found throughout the nervous system that provide various types of support for neurons
axons that carry information outward from the central nervous system to the periphery of the body
the right and left halves of the cerebrum
research method involving destroying a piece of the brain
brain structure that includes the cerebellum, the medulla, and the pons
structure found near the base of the forebrain that is involved in the regulation of basic biological needs
a microscopic gap between the terminal button of one neuron and the cell membrane of another neuron
chemicals that transmit information from one neuron to another
an inherited characteristic that increased in a population because it helped solve a problem of survival or reproduction during the time it emerged
DNA segments that serve as the key functional units in hereditary transmission
internally produced chemicals that resemble opiates in structure and effects
a chemical that opposes the action of a neurotransmitter
a limited time span in the development of an organism when it is optimal for certain capacities to emerge because the organism is especially responsive to certain experiences
research method assessing hereditary influence by examing the resemblance between adopted children and both their biological and adoptive parents
individual cells in the nervous system that receive, integrate, and transmit information
research method involving sending a weak electric current into a brain structure to stimulate it
the insulating material that encases some axons
system consisting of glands that help control bodily functioning
the parts of a neuron that are specialized to receive information
a stable, negative charge when the cell is inactive (about -70 millivolts)
the reproductive success of an individual organism relative to the average reproductive success in the population
characteristics that are influenced by more than one pair of genes
system made up of nerves that connect to voluntary skeletal muscles and to sensory receptors
system made up of nerves that connect to the heart, blood vessels, smooth muscles, and glands
research method assessing hereditary influence by examining blood relatives to see how much they resemble one another on a specific trait
relatively large and deeply folded structure located adjacent to the back surface of the brainstem
the minimum length of time after an action potential during which another action potential cannot begin
