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






2. 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






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






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






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






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






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






8. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






9. Include tolerance (possible withdrawal) and sensitivity






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






11. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






13. 'little brain'






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






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






16. Projects to ventral tegmental area






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






18. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






19. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






20. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






21. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






22. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






23. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






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






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






27. Trigerminal Nerve - face sensation






28. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






29. Symptom of narcolepsy - irresistible urge to






30. Norepinephrine and serotonin






31. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






32. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






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






34. Vestibulocochlear Nerve - hearing and balance






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






36. Holds the lens in place






37. Contains delta activity - stages III and IV






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






39. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






40. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






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






42. Abducens Nerve - moves eye






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






44. Important to motor system






45. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)
