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. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






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






3. 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)






4. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






5. Combines input from diverse brain regions; receives sensory information/sends motor impulses






6. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






7. Vagus Nerve - heart rate and digestion






8. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






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






11. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






12. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






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






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






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






16. Is an oversensitivity to dopamine (D2)






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






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






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






20. 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






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






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






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






24. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






25. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






26. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






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






28. Sleepwalking - sleep talking






29. Regulates body temperature






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






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






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






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






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






35. 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






36. Expression of traits






37. 'little net'






38. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






39. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






40. 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






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






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






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






44. Adenine - Guanine - Thymine - Cytosine






45. 'little brain'






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






47. Produce drowsiness and sleepiness






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. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






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