Behavioral Neuroscience

Subject : health-sciences
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Condition in which a person is alive but unable to communicate or to function independently at even the most basic level.






2. A groove in brain matter - usually a groove found in the neocortex or cerebellum.






3. Synonym for mind - an entity once proposed to be the source of human behavior.






4. Condition in which a person can display some rudimentary behaviors - such as smiling - or utter a few words but is otherwise not conscious.






5. Part of the autonomic nervous system; arouses the body for action - such as mediating the involuntary fight-or-flight response to alarm by increasing hear rate and blood pressure.






6. Part of the central nervous system encased within the vertebrae (spinal column) tat provides most of the connections between the brain and the rest of the body.






7. Central part of the brain that contains neural circuits for hearing and seeing as well as orienting movements.






8. Process in which maturation is delayed - and so an adult retains infant characteristics; idea derived from the observation that newly evolved species resemble the young of their common ancestors.






9. Cerebral cortex where visual processing begins - lying at the back of the brain ad beneath the occipital bone.






10. Division into a number of parts that are similar; refers to the idea that many animals - including vertebrates - are composed of similarly organized body segments.






11. Body plan in which organs or parts present on both sides of the body are mirror images in appearance.






12. Approved experiment directed toward developing a treatment.






13. Major structure of the forebrain - consisting of two virtually identical hemispheres (left and right) and responsible for most conscious behavior.






14. Degenerative brain disorder related to aging that first appears as progressive memory loss and later develops into generalized dementia.

15. One of a set of 12 nerve pairs that control sensory and motor functions of the head - neck - and internal organs.






16. Part of the PNS that includes the cranial and spinal nerves to and from the muscles - joints - and skin that produce movement - transmit incoming sensory input - and inform the CNS about the position and movement of body parts.






17. Central structures of the brain - including the hindbrain - midbrain - thalamus - and hypothalamus - responsible for most unconscious behavior.






18. Disorder of the motor system correlated with a loss of dopamine in the brain an characterized by tremors - muscular rigidity - and a reduction in voluntary movement.

19. Collection of nerve cells that function somewhat like a brain.






20. Clear solution of sodium chloride and other salts that fills the ventricles inside the brain and circulates around the brain and spinal cord beneath the arachnoid layer in the subarachnoid space.






21. Decrease in the activity of a neuron or brain area.






22. Area of the skin supplied with afferent nerve fibers by a single spinal-cord dorsal root.






23. Outer layer of brain-tissue surface composed of neurons; the human cerebral cortex is heavily folded.






24. Fiber system connecting the two cerebral hemispheres to provide a route for direct communication between them.






25. Quandary of explaining a nonmaterial mind in command of a material body.






26. Evolutionarily the newest part of the brain; coordinates advanced cognitive functions such as thinking - planning - and language; contains the limbic system - basal ganglia - and the neocortex.






27. A group of cells forming a cluster that can be identified with special stains to form a functional grouping.






28. Large collection of axons coursing together within the central nervous system.






29. General term referring to primates that walk upright - including all forms of humans - living and extinct.






30. Phylogenetic tree that branches repeatedly - suggesting a taxonomy of organisms based on the time sequence in which evolutionary branches arise.






31. Increase in the activity of a neuron or brain area.






32. Surgical removal of a cerebral hemisphere.






33. Darwin's theory for explaining how new species evolve and how existing species change over time. Differential success in the reproduction of different characteristics (phenotypes) results from the interaction of organisms with their environment.






34. The 'between brain' that integrates sensory and motor information on its way to the cerebral cortex.






35. The nervous system's potential for physical or chemical change that enhances its adaptability to environmental change and its ability to compensate for injury.






36. Proposed nonmaterial entity responsible for intelligence - attention - awareness and consciousness.






37. Philosophical position that holds that behavior can be explained as a function of the nervous system without explanatory recourse to the mind.






38. Movement related to sensory inputs - such as turning the head to see the source of a sound.






39. Part of the autonomic nervous system; acts in opposition to the sympathetic division- for example - preparing the body to rest and digest by reversing the alarm response or stimulating digestion.






40. A specialized 'nerve cell' engaged in information processing.






41. Conducting toward a central nervous system structure.






42. Group of organisms that can interbreed.






43. All the neurons in the body located outside the brain and the spinal cord; provides sensory and motor connections to and from the CNS






44. Evolutionarily the oldest part of the brain; contains pons - medulla - reticular formation - and cerebellum structures that coordinate and control most voluntary and involuntary movements.






45. Harry Jerison's quantitative measure of brain size obtained from the ratio of actual brain size to expected brain size - according to the principle of proper mass - for an animal of a particular body size.






46. Behavior that is characteristic of all members of a species.






47. Roof (area above the ventricle) of the midbrain; its functions are sensory processing - particular visual and auditory - and the production of orienting movements.






48. Forbearer from which two or more lineages or family groups arise and so is ancestral to both groups.






49. Part of the PNS that regulates the functioning of internal organs and glands.






50. Diencephalon structure through which information from all sensory systems is integrated and projected into the appropriate region of the neocortex.
