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. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






2. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






3. Is an oversensitivity to dopamine (D2)






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






5. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






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






7. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






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






10. Projects to ventral tegmental area






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






12. 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






13. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






14. 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)






15. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






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






17. Hypoglossal Nerve - moves the tongue






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






19. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






20. 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






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






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






23. Moving forward






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






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






26. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






27. 'covering'






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






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






30. Optic Nerve - sight






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






32. 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)






33. Symptom of narcolepsy - irresistible urge to






34. Are found in the diencephalon






35. Self-dissolving






36. Vagus Nerve - heart rate and digestion






37. Include tolerance (possible withdrawal) and sensitivity






38. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






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






40. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






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






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






43. Is characteristic of indirect antagonist drugs






44. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






45. 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






46. Caudate nucleus and putamen






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






48. Colored part of the eye






49. Is regulated by the hypothalamus






50. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia
