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






2. Increasing effects/effectiveness of a medication due to repeated administration






3. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






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






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






6. Absolute; relative






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






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






9. The viscous substance between cornea and lens






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






11. Vagus Nerve - heart rate and digestion






12. There are 12 add more






13. 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

14. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






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






16. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






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






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






19. 'little net'






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






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






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






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






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






25. Viscous substance between cornea and lens; transparent substance between lens and retina






26. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






27. Most pervasive excitatory neurotransmitter in the brain






28. Moving forward






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






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






31. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






32. Found in the ventricles and spinal canal






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






34. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






35. Maintains balance/posture and coordinates body movements






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






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






38. Includes the tectum and tegmentum






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






40. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






41. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






43. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






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






45. Midbrain - medulla and the pons






46. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






47. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






48. The female reproductive cycle of mammals other than primates






49. 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






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