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






2. Hypoglossal Nerve - moves the tongue






3. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






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






5. Accessory Nerve - moves the head






6. Hormones that reduce pain






7. Olfactory Nerve - smell






8. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






9. 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






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






11. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






12. 'little brain'






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






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






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






16. Sleepwalking - sleep talking






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






18. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






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






20. Receive incoming sensory information or send out motor impulse commands






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






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






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






24. 'little net'






25. Found in the ventricles and spinal canal






26. Made from within - natural






27. Synchronized EEG activity during its deeper stages






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






29. 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






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






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






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






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






34. Portion of a sensory field to which a cell responds






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






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






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






38. 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

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






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






41. Audition: protrusions on top of midbrain; part of auditory system






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






43. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






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






45. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






47. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






48. Affect multiple receptors; highly preferential to which type of receptor they affect






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






50. Is found in the interior rostral temporal lobe - part of limbic system
