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






2. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






3. Important to motor system






4. Receive incoming sensory information or send out motor impulse commands






5. 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






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






7. 'Roof'






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






9. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






10. Is found between the dura mater and arachnoid mater meninges






11. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






12. The visual image of the world on the retina






13. Hypoglossal Nerve - moves the tongue






14. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






15. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






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






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






18. Self-dissolving






19. Sleepwalking - sleep talking






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






21. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

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






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






24. Norepinephrine and serotonin






25. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






26. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






27. Include tolerance (possible withdrawal) and sensitivity






28. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






29. The female reproductive cycle of mammals other than primates






30. Absolute; relative






31. 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






32. 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






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






34. Hypothalamic-pituitary-adrenal axis -controls stress response






35. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






36. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






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






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






39. Contains delta activity - stages III and IV






40. Colored part of the eye






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






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






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






44. Functions as both a hormone and a neurotransmitter in the brain






45. There are 12 add more






46. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






48. Supernormal






49. Found in the ventricles and spinal canal






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