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. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






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






4. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






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






6. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






7. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






8. Decreasing effects of a medication due to repeated administration






9. 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)

10. 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






11. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






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






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






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






15. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






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






17. 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






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






19. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






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






22. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






23. Caudate nucleus and putamen






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






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






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






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






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






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






30. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






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






32. Is characteristic of indirect antagonists






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






34. Include tolerance (possible withdrawal) and sensitivity






35. ...






36. An area that combines input from diverse brain regions






37. Moving forward






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






39. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






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






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






42. 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






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






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






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






46. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






47. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






48. Consummatory stimulus






49. Measure changes in the electrical resistance of the skin (sweat gland activity)






50. Colored part of the eye
