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






2. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






3. Supernormal






4. 'little net'






5. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






6. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






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






8. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






9. Trigerminal Nerve - face sensation






10. Optic Nerve - sight






11. Hormones that reduce pain






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






13. Is an oversensitivity to dopamine (D2)






14. Projects to ventral tegmental area






15. Glossopharyngeal Nerve - taste swallow






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






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






18. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






19. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






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






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






23. An area that combines input from diverse brain regions






24. Cumulative effects of repeated stimulation from a presynaptic neuron






25. Caudate nucleus and putamen






26. Pass the easiest through the blood-brain barrier






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






28. Norepinephrine and serotonin






29. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






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






31. Symptom of narcolepsy - irresistible urge to






32. Made from within - natural






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






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






35. Synchronized EEG activity during its deeper stages






36. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






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






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






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






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






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






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






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






46. Hypoglossal Nerve - moves the tongue






47. Facial Nerve - moves face and salivates






48. 'little brain'






49. Affect multiple receptors; highly preferential to which type of receptor they affect






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