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. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






2. Has neurons for reflexes






3. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






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






5. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






6. 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






7. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






8. Is regulated by the hypothalamus






9. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






10. 'little net'






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

12. Abducens Nerve - moves eye






13. Is characteristic of indirect antagonists






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






15. Opening in the iris; dilates and contracts allowing different levels of light in






16. Maintains balance/posture and coordinates body movements






17. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






18. 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






19. 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)

20. Include tolerance (possible withdrawal) and sensitivity






21. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






22. Norepinephrine and serotonin






23. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






24. Caudate nucleus and putamen






25. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

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






27. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






28. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






29. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






30. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






32. Produce drowsiness and sleepiness






33. Are found in the diencephalon






34. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






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






36. The female reproductive cycle of mammals other than primates






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






38. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






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






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






41. Referred to as the satiety center; lesions lead to obesity and hyperphagia






42. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






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






44. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






45. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






46. Self-dissolving






47. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






49. Symptom of narcolepsy - irresistible urge to






50. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles
