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






2. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






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






5. Sign






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






7. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






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






9. Transparent substance between lens and retina






10. Caudate nucleus and putamen






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






12. Is an oversensitivity to dopamine (D2)






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






14. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






15. Projects to ventral tegmental area






16. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






18. 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






19. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






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






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






23. Also known as ABLATION - is any surgically induced brain lesion






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






25. 'covering'






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






27. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






29. 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






30. An ovary or teste






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






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






33. Is used to treat Parkinson'S Disease






34. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






35. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






36. Found in the ventricles and spinal canal






37. Trigerminal Nerve - face sensation






38. Vagus Nerve - heart rate and digestion






39. Hypoglossal Nerve - moves the tongue






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






41. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






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






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






44. Oculomotor Nerve - moves eye pupil






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






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






47. Symptom of narcolepsy - irresistible urge to






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






49. Is everything anterior to the central sulcus






50. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)
