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. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






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






3. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






4. Important to motor system






5. 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






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






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






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






9. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






10. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






11. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






12. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






13. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






14. Trigerminal Nerve - face sensation






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






16. 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






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

18. 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

19. Maintains balance/posture and coordinates body movements






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






21. Has a calcium-related role and produces the hormone parathyroid






22. All have similar molecular structure - so many 'dirty' medications






23. Is increased in its production by training/experience and therefore - associated with memory






24. Found in the hypothalamus - function to maintain the water balance in the body






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






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






27. Transparent substance between lens and retina






28. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






29. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






30. Emotional perception and expression (particularly fearful emotions and detection of threat)






31. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






32. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






33. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






34. Oculomotor Nerve - moves eye pupil






35. Are found in the diencephalon






36. Optic Nerve - sight






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






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






39. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






40. 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






41. Sleep tests (i.e. to diagnosis sleep apnea)






42. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






44. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






45. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






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






47. 'little brain'






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






49. 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






50. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important
