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






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






3. Opening in the iris; dilates and contracts allowing different levels of light in






4. 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

5. Is found between the dura mater and arachnoid mater meninges






6. Important to motor system






7. Regulates body temperature






8. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






9. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






10. Projects to ventral tegmental area






11. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






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






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






14. Is everything anterior to the central sulcus






15. All have similar molecular structure - so many 'dirty' medications






16. 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






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






18. 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)






19. Sign






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






21. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






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






24. Are found in the diencephalon






25. Is a peptide neurotransmitter and a natural painkiller and antianxiety






26. Optic Nerve - sight






27. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






28. There are 12 add more






29. 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






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






31. Damage to this are causes clumsiness and loss of balance






32. The viscous substance between cornea and lens






33. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






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






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






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






37. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






38. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






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






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






41. Expression of traits






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






43. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






44. Found in the ventricles and spinal canal

47. Symptom of narcolepsy - irresistible urge to






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






49. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)
