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. Portion of a sensory field to which a cell responds






2. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






3. Vestibulocochlear Nerve - hearing and balance






4. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






5. Abducens Nerve - moves eye






6. Binding of drug to receptor site that doesn'T interfere with the principal ligand






7. Mechanism whereby neurons make connections to new areas to change their connectivity






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






9. ...






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






11. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






12. 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

13. 'little net'






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






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






16. 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






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






18. Produce drowsiness and sleepiness






19. Accessory Nerve - moves the head






20. Is characteristic of indirect antagonist drugs






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






22. Is regulated by the hypothalamus






23. Projects to ventral tegmental area






24. The viscous substance between cornea and lens






25. Also known as ABLATION - is any surgically induced brain lesion






26. 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






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






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






29. The female reproductive cycle of mammals other than primates






30. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






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






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






34. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






35. 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






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






37. The increase in REM sleep seen after a period of REM sleep deprivation






38. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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






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






41. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






42. Made from within - natural






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






44. Glossopharyngeal Nerve - taste swallow






45. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






46. Consummatory stimulus






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






48. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






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