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






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






3. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






4. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






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






7. Include tolerance (possible withdrawal) and sensitivity






8. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






9. The female reproductive cycle of mammals other than primates






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






11. If head is rotated - eye movements occur in the same direction






12. Emotional perception and expression (particularly fearful emotions and detection of threat)






13. 'Roof'






14. All have similar molecular structure - so many 'dirty' medications






15. Decreasing effects of a medication due to repeated administration






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






17. Regulates body temperature






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






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






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






21. 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






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






23. Trochlear Nerve - moves eye






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






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






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






27. Is an oversensitivity to dopamine (D2)






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






29. Skin senses that register the sensations of pressure - warmth and cold






30. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






31. Is characteristic of indirect antagonists






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






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






34. Norepinephrine and serotonin






35. 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

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






37. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






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






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






40. 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)






41. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






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






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






45. 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)






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






47. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






48. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






49. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






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