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






2. Pass the easiest through the blood-brain barrier






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






4. Facial Nerve - moves face and salivates






5. 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






6. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






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






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






11. Regulates body temperature






12. 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






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






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






15. Audition: protrusions on top of midbrain; part of auditory system






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






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






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






19. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






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






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






23. 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






24. Is regulated by the hypothalamus






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






26. Most pervasive excitatory neurotransmitter in the brain






27. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






28. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






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






30. 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






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






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






33. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






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






35. 'little brain'






36. Hormones that reduce pain






37. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






38. 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






39. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






40. ...






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






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






43. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






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






45. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






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






47. 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)


48. 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






49. Accessory Nerve - moves the head






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