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. Absolute; relative






2. Are found in the diencephalon






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






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






5. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






7. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






8. Include tolerance (possible withdrawal) and sensitivity






9. 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)






10. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






11. If head is rotated - eye movements occur in the same direction






12. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






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






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






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






16. An ovary or teste






17. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






18. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






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






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






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






22. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






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






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






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






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






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






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






29. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






30. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






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






32. Sleep tests (i.e. to diagnosis sleep apnea)






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






34. Synchronized EEG activity during its deeper stages






35. 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






36. Midbrain - medulla and the pons






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






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






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






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






41. Made from within - natural






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






43. Expression of traits






44. Most pervasive excitatory neurotransmitter in the brain






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






46. Has neurons for reflexes






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