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. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






2. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






3. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






4. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






5. Most pervasive excitatory neurotransmitter in the brain






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






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






8. Contains delta activity - stages III and IV






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






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






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






12. Is regulated by the hypothalamus






13. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






14. Transparent substance between lens and retina






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






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






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






18. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






19. Is everything anterior to the central sulcus






20. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






22. 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






23. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






24. Accessory Nerve - moves the head






25. Damage to this are causes clumsiness and loss of balance






26. Self-dissolving






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






28. Synchronized EEG activity during its deeper stages






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






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






31. Expression of traits






32. 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






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






34. Norepinephrine and serotonin






35. Colored part of the eye






36. Increasing effects/effectiveness of a medication due to repeated administration






37. 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






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






39. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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






41. Holds the lens in place






42. Olfactory Nerve - smell






43. Dorsal part of midbrain; includes the superior and inferior colliculi






44. 'little net'






45. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






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






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






48. Vestibulocochlear Nerve - hearing and balance






49. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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