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. An area that combines input from diverse brain regions






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






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






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






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






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






7. There are 12 add more






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






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






10. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






11. Hypothalamic-pituitary-adrenal axis -controls stress response






12. Is used to treat Parkinson'S Disease






13. 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






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






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






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






17. Holds the lens in place






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






21. 'Roof'






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






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






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






25. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






26. Oculomotor Nerve - moves eye pupil






27. If head is rotated - eye movements occur in the same direction






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






29. Projects to ventral tegmental area






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






31. Absolute; relative






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






33. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

34. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

35. Olfactory Nerve - smell






36. Skin senses that register the sensations of pressure - warmth and cold






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






38. Is regulated by the hypothalamus






39. The female reproductive cycle of mammals other than primates






40. Hypoglossal Nerve - moves the tongue






41. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






42. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






43. Colored part of the eye






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






45. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






46. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






47. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






48. Most pervasive excitatory neurotransmitter in the brain






49. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






50. 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
