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






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






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






4. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






5. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






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






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






9. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






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






11. Contains delta activity - stages III and IV






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






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






14. Vagus Nerve - heart rate and digestion






15. Accessory Nerve - moves the head






16. Glossopharyngeal Nerve - taste swallow






17. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






18. Hormones that reduce pain






19. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






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






21. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






22. Maintains balance/posture and coordinates body movements






23. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






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






25. Controls sexual activity






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






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






28. Has neurons for reflexes






29. 'little brain'






30. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






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






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






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






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






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






37. Expression of traits






38. Hypoglossal Nerve - moves the tongue






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






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






41. Found in the hypothalamus - function to maintain the water balance in the body






42. Include tolerance (possible withdrawal) and sensitivity






43. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






44. Synchronized EEG activity during its deeper stages






45. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






46. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






47. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






48. Midbrain - medulla and the pons






49. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






50. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)
