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






2. Vestibulocochlear Nerve - hearing and balance






3. Maintains balance/posture and coordinates body movements






4. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






5. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






6. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






8. 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






9. Made from within - natural






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






11. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






12. ...






13. Is characteristic of indirect antagonists






14. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






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






16. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






17. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






18. 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






19. Holds the lens in place






20. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






21. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






22. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






23. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






24. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






25. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






26. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






27. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






28. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






29. Accessory Nerve - moves the head






30. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






31. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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

33. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






34. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






35. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






36. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






37. Dorsal part of midbrain; includes the superior and inferior colliculi






38. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






39. Vision: protrusions on top of the midbrain; part of visual system






40. 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






41. Emotional perception and expression (particularly fearful emotions and detection of threat)






42. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






43. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






44. Some brain communications are with the same side of the body






45. Is found in the interior rostral temporal lobe - part of limbic system






46. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






47. Trochlear Nerve - moves eye






48. Is everything anterior to the central sulcus






49. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






50. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice
