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






2. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






3. 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)

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






5. Is everything anterior to the central sulcus






6. Sleepwalking - sleep talking






7. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






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






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






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






11. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






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






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






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






15. Mechanism whereby neurons make connections to new areas to change their connectivity






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






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






18. ...






19. 'little brain'






20. Vagus Nerve - heart rate and digestion






21. Also known as ABLATION - is any surgically induced brain lesion






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






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






24. Facial Nerve - moves face and salivates






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






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






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






28. 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)






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






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






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






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






33. There are 12 add more






34. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






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






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






38. Caudate nucleus and putamen






39. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






40. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






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






42. Contains delta activity - stages III and IV






43. 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)






44. Most brain communications are with the opposite side of the body






45. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






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






47. Holds the lens in place






48. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

49. Symptom of narcolepsy - irresistible urge to






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