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. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






2. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






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






4. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






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






6. Expression of traits






7. Sign






8. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






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






10. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






11. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






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






13. 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






14. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






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






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






18. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






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






21. Has a calcium-related role and produces the hormone parathyroid






22. The viscous substance between cornea and lens






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






24. Midbrain - medulla and the pons






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






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






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






28. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






29. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






31. 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






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






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






34. 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






35. The female reproductive cycle of mammals other than primates






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






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






38. Is found in the interior rostral temporal lobe - part of limbic system






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






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






41. 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






42. The visual image of the world on the retina






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






44. Hormones that reduce pain






45. If head is rotated - eye movements occur in the same direction






46. Made from within - natural






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






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






49. Supernormal






50. Sleep tests (i.e. to diagnosis sleep apnea)
