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. Vagus Nerve - heart rate and digestion






2. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






3. Is regulated by the hypothalamus






4. Trochlear Nerve - moves eye






5. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






6. Olfactory Nerve - smell






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






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






9. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






10. An area that combines input from diverse brain regions






11. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






12. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






13. 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)






14. Include tolerance (possible withdrawal) and sensitivity






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

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






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






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






19. 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






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






21. ...






22. Expression of traits






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






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






25. Self-dissolving






26. There are 12 add more






27. Oculomotor Nerve - moves eye pupil






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






29. 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

30. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






31. Transparent substance between lens and retina






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






33. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






34. Vestibulocochlear Nerve - hearing and balance






35. Norepinephrine and serotonin






36. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






37. 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)






38. Moving forward






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






40. Affect multiple receptors; highly preferential to which type of receptor they affect






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






42. Projects to ventral tegmental area






43. 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






44. 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






45. Are found in the diencephalon






46. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






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






48. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






49. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






50. Is used to treat Parkinson'S Disease
