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






2. Produce drowsiness and sleepiness






3. 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

4. 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






5. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






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






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






9. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






10. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






11. Vision: protrusions on top of the midbrain; part of visual system






12. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






13. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






14. 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)

15. Cumulative effects of repeated stimulation from a presynaptic neuron






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






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






18. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






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






20. Oculomotor Nerve - moves eye pupil






21. 'little net'






22. Decreasing effects of a medication due to repeated administration






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






24. 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






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






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






27. Is used as an anaesthetic for children and animals but causes psychosis in adults






28. Also known as ABLATION - is any surgically induced brain lesion






29. 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)






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






31. 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






32. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






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






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






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






36. Caudate nucleus and putamen






37. Combines input from diverse brain regions; receives sensory information/sends motor impulses






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






39. Optic Nerve - sight






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






41. Maintains balance/posture and coordinates body movements






42. Is characteristic of indirect antagonists






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






44. Most brain communications are with the opposite side of the body






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






46. Synchronized EEG activity during its deeper stages






47. Pass the easiest through the blood-brain barrier






48. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






49. Is characteristic of indirect antagonist drugs






50. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands
