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. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






2. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






3. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






4. Made from within - natural






5. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






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






7. Found in the hypothalamus - function to maintain the water balance in the body






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






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






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






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






12. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






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






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






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






16. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






17. Transparent substance between lens and retina






18. Maintains balance/posture and coordinates body movements






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






20. Vagus Nerve - heart rate and digestion






21. Glossopharyngeal Nerve - taste swallow






22. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






23. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






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






25. 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)






26. 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






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






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






29. 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






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






31. Accessory Nerve - moves the head






32. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






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






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






35. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






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






38. 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






39. Are found in the diencephalon






40. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






41. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

42. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






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






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






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






46. Decreasing effects of a medication due to repeated administration






47. Symptom of narcolepsy - irresistible urge to






48. Midbrain - medulla and the pons






49. Hormones that reduce pain






50. Hypothalamic-pituitary-adrenal axis -controls stress response
