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. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






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






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






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






5. Is everything anterior to the central sulcus






6. Maintains balance/posture and coordinates body movements






7. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






8. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






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






10. Supernormal






11. 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)

12. Sleepwalking - sleep talking






13. 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)






14. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






16. Expression of traits






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






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






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






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






21. Increasing effects/effectiveness of a medication due to repeated administration






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






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






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






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






26. Is used to treat Parkinson'S Disease






27. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






28. Midbrain - medulla and the pons






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






30. The increase in REM sleep seen after a period of REM sleep deprivation






31. Decreasing effects of a medication due to repeated administration






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






33. Most pervasive excitatory neurotransmitter in the brain






34. Important to motor system






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






36. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






37. A single - unfertilized cell created during conception; the combined egg + sperm






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






39. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






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






41. 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

42. Abducens Nerve - moves eye






43. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






44. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






46. Are found in the diencephalon






47. Trigerminal Nerve - face sensation






48. There are 12 add more






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






50. Accessory Nerve - moves the head
