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. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






2. Adenine - Guanine - Thymine - Cytosine






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






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






5. Expression of traits






6. ...






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






8. Vagus Nerve - heart rate and digestion






9. Colored part of the eye






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






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






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. The increase in REM sleep seen after a period of REM sleep deprivation






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






15. 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)






16. Most pervasive excitatory neurotransmitter in the brain






17. Olfactory Nerve - smell






18. Precursor to the catecholamine neurotransmitters (DA + NE)






19. 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






20. Receive incoming sensory information or send out motor impulse commands






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






22. Contains delta activity - stages III and IV






23. The female reproductive cycle of mammals other than primates






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






25. Cumulative effects of repeated stimulation from a presynaptic neuron






26. 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






27. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






28. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






29. Facial Nerve - moves face and salivates






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






31. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






32. Oculomotor Nerve - moves eye pupil






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






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






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






36. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






37. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






38. Caudate nucleus and putamen






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






40. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






41. Are found in the diencephalon






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






43. Absolute; relative






44. Accessory Nerve - moves the head






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






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






47. 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






48. Synchronized EEG activity during its deeper stages






49. Self-dissolving






50. 'little net'
