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






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






3. Subcortical forebrain nuclei that coordinate voluntary movements of the limbs and body; connected to the thalamus and to the midbrain.






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






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






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






7. Neurosurgery in which electrodes implanted in the brain stimulate a targeted area with a low-voltage electrical current to facilitate behavior.






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






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






10. Map of the neocortex based on the organization - structure - and distribution of the cells.






11. 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.

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






13. Newest - outer layer (new bark) of the forebrain and composed of about six layers of gray matter that creates or reality.






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






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. 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.






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






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






19. 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.






20. Group of organisms that can interbreed.






21. Conducting away from the central nervous system structure.






22. 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.






23. 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.






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






25. Conducting toward a central nervous system structure.






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






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






28. Surgical removal of a cerebral hemisphere.






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






30. Areas of the nervous system composed predominantly of cell bodies and blood vessels that function either to collect and modify information or to support this activity.






31. 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.






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






33. Learned behaviors that are passed on from on generation to the next through teaching and experience.






34. Three layers of protective tissue - dura mater - arachnoid - and pia mater - that encase the brain and spinal cord.






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






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






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






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

39. 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.






40. 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.






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






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






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






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






45. That holds that both a nonmaterial mind and the material body contribute to behavior.






46. 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.






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






48. 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.






49. 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.






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