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. Made from within - natural






2. 'Roof'






3. Self-dissolving






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






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






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






7. Abducens Nerve - moves eye






8. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






9. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






10. Contains delta activity - stages III and IV






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






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






13. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






14. Is a peptide neurotransmitter and a natural painkiller and antianxiety






15. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






17. 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






18. The female reproductive cycle of mammals other than primates






19. 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

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






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






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






23. Sign






24. Expression of traits






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






26. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






27. Is everything anterior to the central sulcus






28. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






30. Olfactory Nerve - smell






31. Important to motor system






32. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






33. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






34. 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)






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






36. Most pervasive excitatory neurotransmitter in the brain






37. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






38. 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






39. The viscous substance between cornea and lens






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






41. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






42. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






43. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






44. Is an oversensitivity to dopamine (D2)






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






46. 'covering'






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






48. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






49. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






50. Is characteristic of indirect antagonist drugs
