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.

10. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






11. 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)






12. Functions as both a hormone and a neurotransmitter in the brain






13. Pass the easiest through the blood-brain barrier






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






15. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






16. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






17. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






18. There are 12 add more






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






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






21. Sleep tests (i.e. to diagnosis sleep apnea)






22. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






23. Most brain communications are with the opposite side of the body






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






25. 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






26. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






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






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






29. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






30. ...






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






32. An ovary or teste






33. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






35. Midbrain - medulla and the pons






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






37. Glossopharyngeal Nerve - taste swallow






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






39. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






40. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






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






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






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






44. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






45. 'Roof'






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






47. Hypoglossal Nerve - moves the tongue






48. Include tolerance (possible withdrawal) and sensitivity






49. Made from within - natural
