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. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

2. Contains delta activity - stages III and IV






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






4. Self-dissolving






5. Oculomotor Nerve - moves eye pupil






6. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






7. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






8. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






9. 'little brain'






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






11. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






12. Damage to this are causes clumsiness and loss of balance






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






14. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






15. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






16. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






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






18. 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






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






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






21. 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)






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






23. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






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






25. Expression of traits






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






27. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






28. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






29. ...






30. Are found in the diencephalon






31. Is everything anterior to the central sulcus






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






33. 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






34. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






35. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






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






37. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






38. Is a peptide neurotransmitter and a natural painkiller and antianxiety






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






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






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






42. Consummatory stimulus






43. Hormones that reduce pain






44. Combines input from diverse brain regions; receives sensory information/sends motor impulses






45. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






47. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






48. Important to motor system






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






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