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






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






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






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






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






6. 'little net'






7. Symptom of narcolepsy - irresistible urge to






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






9. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






10. Pleasure center of the brain; discovered by Olds & Milner






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






12. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






13. 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)






14. Is increased in its production by training/experience and therefore - associated with memory






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






16. Skin senses that register the sensations of pressure - warmth and cold






17. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






18. 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






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






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






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






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






23. Midbrain - medulla and the pons






24. Maintains balance/posture and coordinates body movements






25. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






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






27. Hypoglossal Nerve - moves the tongue






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






29. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






30. Projects to ventral tegmental area






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






32. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






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






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






35. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






36. Trochlear Nerve - moves eye






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






38. Produce drowsiness and sleepiness






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






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






41. Norepinephrine and serotonin






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






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






44. Caudate nucleus and putamen






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






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






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






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






49. Moving forward






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