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. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






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






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






4. Symptom of narcolepsy - irresistible urge to






5. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






7. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






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






9. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






10. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






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






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






13. 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






14. Sleepwalking - sleep talking






15. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






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






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






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






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






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






22. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






23. Are found in the diencephalon






24. Projects to ventral tegmental area






25. Absolute; relative






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






27. The maintenance of water balance in the body






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






29. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






30. Precursor to the catecholamine neurotransmitters (DA + NE)






31. Is a peptide neurotransmitter and a natural painkiller and antianxiety






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






33. 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)






34. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






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






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






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






39. Viscous substance between cornea and lens; transparent substance between lens and retina






40. Vision: protrusions on top of the midbrain; part of visual system






41. Oculomotor Nerve - moves eye pupil






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






43. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






44. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






46. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






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






48. Sign






49. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






50. 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)
