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. 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)






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






3. 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






4. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






5. 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






6. Olfactory Nerve - smell






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






8. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






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






10. Absolute; relative






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






12. 'covering'






13. 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






14. 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






15. 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

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






17. The maintenance of water balance in the body






18. The visual image of the world on the retina






19. 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






20. 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






21. Include tolerance (possible withdrawal) and sensitivity






22. Damage to this are causes clumsiness and loss of balance






23. 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






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






25. 'little brain'






26. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






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






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






30. 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






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






32. There are 12 add more






33. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






35. Norepinephrine and serotonin






36. Made from within - natural






37. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






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






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






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






41. 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)






42. Are found in the diencephalon






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






44. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






45. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






46. Self-dissolving






47. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






48. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






49. Found in the ventricles and spinal canal






50. 'little net'
