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






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






3. The visual image of the world on the retina






4. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






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

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






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






8. Oculomotor Nerve - moves eye pupil






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






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






11. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






12. Produce drowsiness and sleepiness






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






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






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






16. Are found in the diencephalon






17. 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






18. 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






19. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






20. Binding of drug to receptor site that doesn'T interfere with the principal ligand






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






22. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






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






25. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






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






27. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






28. 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






29. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






30. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






31. The viscous substance between cornea and lens






32. 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






33. Hormones that reduce pain






34. Sleepwalking - sleep talking






35. Include tolerance (possible withdrawal) and sensitivity






36. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






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






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






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






41. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






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






43. 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






44. 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)






45. An area that combines input from diverse brain regions






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






47. Is an oversensitivity to dopamine (D2)






48. 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






49. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






50. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)
