Gre Psychology: Experimental/natural Science Biology

Subjects : gre, psychology
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. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






2. Sleep tests (i.e. to diagnosis sleep apnea)






3. In the CNS - is an amino acid that stabilizes neural activity






4. Contains delta activity - stages III and IV






5. Midbrain - medulla and the pons






6. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






7. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






8. ...






9. Maintains balance/posture and coordinates body movements






10. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






11. Increasing effects/effectiveness of a medication due to repeated administration






12. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






13. Functions as both a hormone and a neurotransmitter in the brain






14. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






15. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






16. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






17. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






18. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






19. Are found in the diencephalon






20. Also known as ABLATION - is any surgically induced brain lesion






21. Mechanism whereby neurons make connections to new areas to change their connectivity






22. Made from within - natural






23. Measure changes in the electrical resistance of the skin (sweat gland activity)






24. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






25. If head is rotated - eye movements occur in the same direction






26. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






27. 'little net'






28. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






29. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






30. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






31. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






32. Is increased in its production by training/experience and therefore - associated with memory






33. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






34. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






35. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






36. Two different presynaptic neurons/inputs to a post-synaptic cell






37. Found in the ventricles and spinal canal






38. Facial Nerve - moves face and salivates






39. Most pervasive excitatory neurotransmitter in the brain






40. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






41. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






42. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






43. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

44. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






45. A single - unfertilized cell created during conception; the combined egg + sperm






46. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






47. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






48. Audition: protrusions on top of midbrain; part of auditory system






49. Pleasure center of the brain; discovered by Olds & Milner






50. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell
