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. 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






2. 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

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






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






5. Most pervasive excitatory neurotransmitter in the brain






6. 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






7. Projects to ventral tegmental area






8. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






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






11. Trochlear Nerve - moves eye






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






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






14. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






15. Glossopharyngeal Nerve - taste swallow






16. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






18. Important to motor system






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






20. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






21. 'covering'






22. Includes the tectum and tegmentum






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






24. Holds the lens in place






25. 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






26. Made from within - natural






27. Accessory Nerve - moves the head






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






29. 'Roof'






30. Transparent substance between lens and retina






31. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






32. Measure changes in the electrical resistance of the skin (sweat gland activity)






33. Decreasing effects of a medication due to repeated administration






34. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






35. Regulates body temperature






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






37. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






39. Is used to treat Parkinson'S Disease






40. Is everything anterior to the central sulcus






41. Moving forward






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






43. Is an oversensitivity to dopamine (D2)






44. Is found between the dura mater and arachnoid mater meninges






45. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






46. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






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






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






49. Optic Nerve - sight






50. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain
