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. The brain and spinal cord that together mediate behavior.






2. The general principle that sensory fibers are located dorsally and motors fibers are located ventrally.






3. Hypothesis that the movements that we make and those that we perceive in others are essential features of our conscious behavior.






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






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






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






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






8. Group of organisms that can interbreed.






9. Midbrain area in which nuclei and fiber pathways are mixed - producing a netlike appearance; associated with sleep-wake behavior and behavioral arousal.






10. 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.






11. The bones - or segments - that form the spinal column.






12. 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.






13. A small protrusion or bump formed by the folding of the cerebral cortex.






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






15. Cerebral Cortex often generally characterized as performing the brain's 'executive' functions - such as decision making - lying anterior to the central sulcus and beneath the frontal bone of the skull.






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






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






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






19. Wound to the brain that results from a blow to the head..






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






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






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






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






24. Animal that has both a brain and a spinal cord.






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






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






27. One of four cavities in the brain that contain cerebrospinal fluid that cushions the brain and may play a role in maintaining brain metabolism.






28. Condition in which a person is alive but unable to communicate or to function independently at even the most basic level.






29. Disorder of the basal ganglia characterized by tics; involuntary vocalizations (including curse words and animal sounds); and odd - involuntary movements of the body; especially of the face and head.

30. 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.






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

32. Conducting toward a central nervous system structure.






33. Literally - half a sphere - referring to one side of the cerebral cortex or of one side of the cerebellum.






34. Major structure of the brainstem specialized for coordinating and learning skilled movements. In large-brained animals - it may also have a role in the coordination of other mental processes.






35. Floor (area below the ventricle) of the midbrain; a collection of nuclei with movement-related - species-specific - and pain-perception functions.






36. Simple nervous system that has no brain or spinal cord but consists of neurons that receive sensory information and connect directly to other neurons that move muscles.






37. Disparate forebrain structures lying between the neocortex and the brainstem that form a functional system controlling affective and motivated behaviors and certain forms of memory; includes cingulate cortex - amygdala - hippocampus - among other str






38. Idea that selection for improved brain cooling through increased blood circulation in the brains of early hominids enabled the brain to grow larger.






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






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






42. 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.






43. Of the mind; an explanation of behavior as a function of the nonmaterial mind.






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






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






46. 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.

47. Cerebral Cortex that functions to direct movements toward a goal or to perform a task - such as grasping an object - lying posterior to the central sulcus and beneath the parietal bone at the top of the skull.






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






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






50. Areas of the nervous system rich in fat-sheathed neural axons that form the connections between brain cells.
