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. Precursor to the catecholamine neurotransmitters (DA + NE)






2. 'covering'






3. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






5. Is everything anterior to the central sulcus






6. Is characteristic of indirect antagonist drugs






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






8. Vagus Nerve - heart rate and digestion






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






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






11. Synchronized EEG activity during its deeper stages






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






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






15. The visual image of the world on the retina






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






17. Self-dissolving






18. The maintenance of water balance in the body






19. Is found between the dura mater and arachnoid mater meninges






20. Controls sexual activity






21. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






22. 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)






23. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






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






25. 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






26. Skin senses that register the sensations of pressure - warmth and cold






27. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






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






29. 'Roof'






30. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






32. Facial Nerve - moves face and salivates






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






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






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. 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)






37. Holds the lens in place






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






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






40. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






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






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






44. Caudate nucleus and putamen






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






46. 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






47. Expression of traits






48. The viscous substance between cornea and lens






49. 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

50. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)
