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






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






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






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






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






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






7. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






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






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






10. Made from within - natural






11. Pleasure center of the brain; discovered by Olds & Milner






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






13. 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






14. Projects to ventral tegmental area






15. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






16. Vestibulocochlear Nerve - hearing and balance






17. 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






18. A single - unfertilized cell created during conception; the combined egg + sperm






19. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






20. 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






21. Glossopharyngeal Nerve - taste swallow






22. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






23. 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






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






25. The visual image of the world on the retina






26. Regulates body temperature






27. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






28. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






29. 'little net'






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






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






32. In the CNS - is an amino acid that stabilizes neural activity






33. Found in the ventricles and spinal canal






34. Some brain communications are with the same side of the body






35. Viscous substance between cornea and lens; transparent substance between lens and retina






36. 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






37. 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






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






39. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






40. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






41. 'covering'






42. An ovary or teste






43. Contains delta activity - stages III and IV






44. The increase in REM sleep seen after a period of REM sleep deprivation






45. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






46. Portion of a sensory field to which a cell responds






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






48. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






49. Hormones that reduce pain






50. 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
