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






2. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






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






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






5. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






6. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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






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






9. Viscous substance between cornea and lens; transparent substance between lens and retina






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






11. Produce drowsiness and sleepiness






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






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






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






15. 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)






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






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






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






19. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






20. Has neurons for reflexes






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






22. Precursor to the catecholamine neurotransmitters (DA + NE)






23. Projects to ventral tegmental area






24. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






25. 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)






26. An ovary or teste






27. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






29. 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






30. Colored part of the eye






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






32. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






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






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






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






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






37. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






39. 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






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






41. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






42. Symptom of narcolepsy - irresistible urge to






43. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






44. Includes the tectum and tegmentum






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






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






47. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






48. Vestibulocochlear Nerve - hearing and balance






49. Abducens Nerve - moves eye






50. Pleasure center of the brain; discovered by Olds & Milner
