  1. A cell that responds to a particular form of energy. Often a specialized neuron

  14. Encodes sound identity
    Ventral stream
  15. Neurons fire at the same rate as the vibration of the sound source...aka the telephone theory
    Frequency Theory
  16. A theory that states neurons can follow the frequency of a sound by combining responses of groups of individual neurons.
    Volley Theory
  17. The ability to distinguish an individual sound source in a complex auditory enviroment
    Cocktail party effect
  18. Using two ears
    Binaural
  19. This cue works best at low frequencies which can pass through the head

  25. The inability to read
    Dyslexia
  26. The adequate stimulus of visible light which makes up 1/70th of the electromagnetic spectrum
    The Visible spectrum
  27. Rods and cones are found in this area of the eye which is the photorecpetor of light
    Retina
  28. Reacts to light
    Photopigment
  29. Reacts to lights in rods
    Rhodopsin
  30. Reacts to light in cones
    lodopsin
  31. The area of the retina from which a ganglion cell recieves its input
    Receptive field
  32. The part of the environment that is being registered on the retina
    Visual field
  33. The discrepancy in the locaiton of an image on the two retinas providing one of the depth cues
    Retina disparity
  34. Young and Helmhlotz proposed that only 3 types of color receptors (red, green, blue) is detectable in every visible color
    Trichromatic Theory
  35. Recognized that yellow is also one of the primary colors but proposed the eye only has 2 color receptors (one for red and green, and another for bue and yellow
    Opponent Process Theory
  36. Hurvich and Jameson proposed 3 types of color receptors (red, green and blue)
    Combined Theory
  37. Located in the visual cortex
    Retinotpic map
  38. The detection of an objects' boundaries and features
    Form vision
  39. Responds to a line or an edge at a specific orientation and a specific place on the retina
    Simple cells
  40. Continue to respond when a line or edge moves to a new location near the original site
    Complex cells
  41. Visual cortical cells do a Fourier frequency analysis of the luminosity variations in the environment while some complex cells respond to high and low frequencies
    Spatial Frequency Theory
  42. Information is processed by ascending through increasingly complex levels of the nervous system
    Hierarchial Processing
  43. Visual processing occurs across a wide area of the brain
    Distributed Processing
  44. Originates from ganglion cells located mainly in the fovea with small color opponent circular receptive fields. This system is specialized for detail and color
    Parvocelluar system
  45. Originates from the ganglion cells with large, brightness-opponent circular receptive fields that respond only briefly to stimulation. It is particuarly effective at analyzing brigthness contrast and movement
    Magnocellular system
  46. Handles the "what" of processing and progresses through V1, V2 and into V4 where color is percieved then to the infereior temporal lobes and is dominated by the parvocelluar system
    Ventral stream
  47. Handles the "where" of processing and flows from the visual cortex to the parietal lobes and is dominated by the magnocellular system.
    Dorsal stream
  48. Arrives in areas of V1 that respond to orientation, movement and retina disparity, then proceeds through V2 and V5 (MT), where movement is percieved then on to the posterior parietal cortex
    Dorsal stream
