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






2. 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






3. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






4. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






5. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






6. Receive incoming sensory information or send out motor impulse commands






7. 'little net'






8. There are 12 add more






9. 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

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






11. Transparent substance between lens and retina






12. Is used to treat Parkinson'S Disease






13. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






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






15. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






16. Moving forward






17. Symptom of narcolepsy - irresistible urge to






18. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






19. Trigerminal Nerve - face sensation






20. 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






21. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






22. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






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






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






25. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






26. The viscous substance between cornea and lens






27. Caudate nucleus and putamen






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






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






30. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






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






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






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






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






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






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






37. Referred to as the satiety center; lesions lead to obesity and hyperphagia






38. Is regulated by the hypothalamus






39. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






40. 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)

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






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






43. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






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






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






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






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

48. The maintenance of water balance in the body






49. Norepinephrine and serotonin






50. Decreasing effects of a medication due to repeated administration
