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






2. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






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






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






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






6. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






7. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

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






9. Abducens Nerve - moves eye






10. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

11. Contains delta activity - stages III and IV






12. Vision: protrusions on top of the midbrain; part of visual system






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






14. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






15. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






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






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






18. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






19. Is used as an anaesthetic for children and animals but causes psychosis in adults






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






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






22. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






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






24. Most brain communications are with the opposite side of the body






25. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






26. 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)






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






28. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






29. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






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






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






32. Oculomotor Nerve - moves eye pupil






33. 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)






34. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






35. Glossopharyngeal Nerve - taste swallow






36. In the CNS - is an amino acid that stabilizes neural activity






37. Audition: protrusions on top of midbrain; part of auditory system






38. Caudate nucleus and putamen






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






40. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






41. An ovary or teste






42. Is regulated by the hypothalamus






43. Absolute; relative






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






45. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






46. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






47. 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

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






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






50. Cumulative effects of repeated stimulation from a presynaptic neuron
