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






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






3. Abducens Nerve - moves eye






4. Dorsal part of midbrain; includes the superior and inferior colliculi






5. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






6. Accessory Nerve - moves the head






7. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






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






9. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






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






12. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






13. Include tolerance (possible withdrawal) and sensitivity






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






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






16. The maintenance of water balance in the body






17. 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)






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






19. 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

20. Opening in the iris; dilates and contracts allowing different levels of light in






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






22. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






23. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






25. Is an oversensitivity to dopamine (D2)






26. Pass the easiest through the blood-brain barrier






27. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






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






29. 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)

30. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






31. Facial Nerve - moves face and salivates






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






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






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






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






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






37. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






38. Absolute; relative






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






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






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






42. 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






43. Has neurons for reflexes






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






45. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






46. 'little brain'






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






48. Is increased in its production by training/experience and therefore - associated with memory






49. Are found in the diencephalon






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