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. Vestibulocochlear Nerve - hearing and balance






2. 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






3. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






5. 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






6. Two different presynaptic neurons/inputs to a post-synaptic cell






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






8. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






9. Colored part of the eye






10. Measure changes in the electrical resistance of the skin (sweat gland activity)






11. Made from within - natural






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






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






14. Absolute; relative






15. 'little brain'






16. Cumulative effects of repeated stimulation from a presynaptic neuron






17. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






18. 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)






19. Important to motor system






20. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






21. 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






22. 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






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






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






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






26. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






27. Increasing effects/effectiveness of a medication due to repeated administration






28. Includes the tectum and tegmentum






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






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






31. Produce drowsiness and sleepiness






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






33. 'little net'






34. Midbrain - medulla and the pons






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






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






37. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






38. 'Roof'






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






40. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






41. Regulates body temperature






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






43. Synchronized EEG activity during its deeper stages






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






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

46. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






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






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






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






50. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath
