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






2. Made from within - natural






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






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






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






6. Found in the ventricles and spinal canal






7. Important to motor system






8. Facial Nerve - moves face and salivates






9. Supernormal






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






11. Transparent substance between lens and retina






12. Optic Nerve - sight






13. Regulates body temperature






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






15. Midbrain - medulla and the pons






16. 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






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






18. 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






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






20. Sign






21. Include tolerance (possible withdrawal) and sensitivity






22. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






23. Tremors - rigidity of limbs - poor balance and difficulty initiating movements


24. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






25. 'Roof'






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






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






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






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






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






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






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






34. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






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






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






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






38. Synchronized EEG activity during its deeper stages






39. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






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






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






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






43. Are found in the diencephalon






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






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






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






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






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






49. Vagus Nerve - heart rate and digestion






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