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






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






4. Functions as both a hormone and a neurotransmitter in the brain






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






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






7. Referred to as the satiety center; lesions lead to obesity and hyperphagia






8. Hypoglossal Nerve - moves the tongue






9. ...






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






11. There are 12 add more






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






13. 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






14. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






16. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






17. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






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






19. Hormones that reduce pain






20. Holds the lens in place






21. 'covering'






22. Found in the ventricles and spinal canal






23. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






24. 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






25. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






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






27. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






28. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






29. Self-dissolving






30. Is used to treat Parkinson'S Disease






31. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






32. Transparent substance between lens and retina






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

34. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






35. If head is rotated - eye movements occur in the same direction






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






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






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






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






40. The maintenance of water balance in the body






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






42. Viscous substance between cornea and lens; transparent substance between lens and retina






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






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






45. 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






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






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






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. Regulates body temperature






50. Caudate nucleus and putamen
