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






2. Absolute; relative






3. Is regulated by the hypothalamus






4. Transparent substance between lens and retina






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






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






7. 'covering'






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






9. Caudate nucleus and putamen






10. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






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






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






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






14. Vestibulocochlear Nerve - hearing and balance






15. The viscous substance between cornea and lens






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






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






18. Is characteristic of indirect antagonist drugs






19. Norepinephrine and serotonin






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






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






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






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






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






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






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






27. Is characteristic of indirect antagonists






28. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






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






30. Pass the easiest through the blood-brain barrier






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






32. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






33. 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






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






35. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






36. Sleepwalking - sleep talking






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






38. Supernormal






39. 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






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






41. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






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






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






44. Colored part of the eye






45. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






46. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






47. ...






48. 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)

49. Found in the ventricles and spinal canal






50. Glossopharyngeal Nerve - taste swallow
