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. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






2. Includes the tectum and tegmentum






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






4. Self-dissolving






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






6. Hypoglossal Nerve - moves the tongue






7. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






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






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






11. Pleasure center of the brain; discovered by Olds & Milner






12. Dorsal part of midbrain; includes the superior and inferior colliculi






13. Sleepwalking - sleep talking






14. ...






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






16. An ovary or teste






17. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






18. 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)






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






20. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)






21. Absolute; relative






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






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






24. Mechanism whereby neurons make connections to new areas to change their connectivity






25. Controls sexual activity






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






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






28. Midbrain - medulla and the pons






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






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






31. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






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






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






34. Decreasing effects of a medication due to repeated administration






35. Colored part of the eye






36. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






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






38. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






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






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






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






42. Norepinephrine and serotonin






43. 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)






44. Hormones that reduce pain






45. 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






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






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






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






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






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