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






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






3. Important to motor system






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






5. 'little net'






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






7. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






9. Has neurons for reflexes






10. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






11. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






12. Contains delta activity - stages III and IV






13. Norepinephrine and serotonin






14. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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. 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






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






18. Has a calcium-related role and produces the hormone parathyroid






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






20. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






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






23. The maintenance of water balance in the body






24. Consummatory stimulus






25. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






26. Optic Nerve - sight






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






28. Maintains balance/posture and coordinates body movements






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






30. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






31. Affect multiple receptors; highly preferential to which type of receptor they affect






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






33. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






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






35. Vestibulocochlear Nerve - hearing and balance






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






37. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






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






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. Viscous substance between cornea and lens; transparent substance between lens and retina






42. 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






43. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






44. All have similar molecular structure - so many 'dirty' medications






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






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






47. Trigerminal Nerve - face sensation






48. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






49. Regulates body temperature






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