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 peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






2. Is everything anterior to the central sulcus






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






4. Glossopharyngeal Nerve - taste swallow






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






6. 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






7. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






8. Includes the tectum and tegmentum






9. 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






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






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






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






13. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






14. The maintenance of water balance in the body






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






16. 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

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






18. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






19. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






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






21. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






22. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

23. Controls sexual activity






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






25. Combines input from diverse brain regions; receives sensory information/sends motor impulses






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






27. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






28. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






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






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






31. Oculomotor Nerve - moves eye pupil






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






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






34. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






35. Adenine - Guanine - Thymine - Cytosine






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






37. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






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






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






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






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






42. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






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






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






47. Regulates body temperature






48. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






49. 'covering'






50. 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)
