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. Oculomotor Nerve - moves eye pupil






2. Facial Nerve - moves face and salivates






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






4. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






5. The viscous substance between cornea and lens






6. Synchronized EEG activity during its deeper stages






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






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






9. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






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






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






12. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






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






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






15. Transparent substance between lens and retina






16. 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






17. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






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






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






20. Caudate nucleus and putamen






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






22. 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






23. Opening in the iris; dilates and contracts allowing different levels of light in






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






25. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






26. Abducens Nerve - moves eye






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






28. 'little net'






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






30. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






31. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






33. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






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






35. Accessory Nerve - moves the head






36. 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)






37. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






38. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






39. 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






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






41. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






42. Optic Nerve - sight






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






44. Is an oversensitivity to dopamine (D2)






45. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






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






48. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






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






50. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response
