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






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






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






4. Midbrain - medulla and the pons






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






6. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






7. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






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






9. Binding of drug to receptor site that doesn'T interfere with the principal ligand






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






11. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






12. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






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






14. Symptom of narcolepsy - irresistible urge to






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






16. Colored part of the eye






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






18. Trochlear Nerve - moves eye






19. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






20. Has neurons for reflexes






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






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






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






24. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






25. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






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






27. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






28. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






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






30. Contains delta activity - stages III and IV






31. Is increased in its production by training/experience and therefore - associated with memory






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






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






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






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






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






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






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






39. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

40. Includes the tectum and tegmentum






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






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






43. 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)






44. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






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






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






47. 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)






48. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






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






50. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)
