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. Some brain communications are with the same side of the body






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






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






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






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






6. Optic Nerve - sight






7. Emotional perception and expression (particularly fearful emotions and detection of threat)






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






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






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






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






12. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






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






14. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






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






16. Symptom of narcolepsy - irresistible urge to






17. Hypoglossal Nerve - moves the tongue






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






19. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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






21. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






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






23. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






24. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






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






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






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






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






29. 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






30. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






31. 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)

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






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






34. Supernormal






35. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






36. Portion of a sensory field to which a cell responds






37. Is characteristic of indirect antagonists






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






39. 'Roof'






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






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






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






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






44. Caudate nucleus and putamen






45. Includes the tectum and tegmentum






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






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






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






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






50. Pass the easiest through the blood-brain barrier
