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






2. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






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






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






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






6. ...






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






8. Synchronized EEG activity during its deeper stages






9. Is an oversensitivity to dopamine (D2)






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






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






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






13. The maintenance of water balance in the body






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






15. Is a peptide neurotransmitter and a natural painkiller and antianxiety






16. 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)






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






18. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






22. Holds the lens in place






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






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






25. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






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






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






28. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






29. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






30. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






31. Is found in the interior rostral temporal lobe - part of limbic system






32. An ovary or teste






33. 'covering'






34. The viscous substance between cornea and lens






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






36. Dorsal part of midbrain; includes the superior and inferior colliculi






37. Is used to treat Parkinson'S Disease






38. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






39. 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






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






41. Includes the tectum and tegmentum






42. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






43. Trochlear Nerve - moves eye






44. The visual image of the world on the retina






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






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






47. Portion of a sensory field to which a cell responds






48. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






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






50. Vestibulocochlear Nerve - hearing and balance
