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. Decreasing effects of a medication due to repeated administration






2. 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






3. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






4. 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)






5. Vagus Nerve - heart rate and digestion






6. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery






7. Moving forward






8. Colored part of the eye






9. The female reproductive cycle of mammals other than primates






10. ...






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






12. Accessory Nerve - moves the head






13. Found in the ventricles and spinal canal






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






15. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






16. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






17. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






18. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






19. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






20. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






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






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






23. Is everything anterior to the central sulcus






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






25. 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






26. Adenine - Guanine - Thymine - Cytosine






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






28. The viscous substance between cornea and lens






29. Expression of traits






30. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






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






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






33. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






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






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






36. Maintains balance/posture and coordinates body movements






37. 'covering'






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






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






40. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






41. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






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






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






44. Hypoglossal Nerve - moves the tongue
