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. 'little brain'






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






3. Sign






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






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






6. 'covering'






7. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






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






9. 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






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






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






12. The female reproductive cycle of mammals other than primates






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






14. 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






15. ...






16. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






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






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






19. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






20. Precursor to the catecholamine neurotransmitters (DA + NE)






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






22. The maintenance of water balance in the body






23. There are 12 add more






24. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






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






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






27. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






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






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






30. Most pervasive excitatory neurotransmitter in the brain






31. 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

32. Has neurons for reflexes






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






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






35. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






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






37. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






38. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






39. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






41. Is found in the interior rostral temporal lobe - part of limbic system






42. Contains delta activity - stages III and IV






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






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






45. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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

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






48. 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






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






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