  1. 1Considering the selectivity for eye of origin. Which eye(s) would a cell in the ocular dominance range of 4 comes from?
    1. ABoth eyes equally
    2. BMostly left eye
    3. CMostly right eye
    4. DRight eye only
    5. ELeft eye only
  2. 2The ocular dominances of 1 & 7 are...
    1. AMonocular
    2. BBinocular
    3. CMonocle
    4. DTrinoculor
    5. EStereoscopic vision
  3. 3The range of orientations a particular cell fires to is called its..
    1. ABandwidth
    2. BPreferred Orientation
    3. CSelective Orientation
    4. DOrientation selectivity
    5. EBroadband
  4. 4Input from both eyes and all 180 degrees of orientation selectivity in a section of V1 is called a...
    1. AHypercolumn
    2. B360 degrees column (2 eyes at 180 degrees each)
    3. CComplex column
    4. DColumn of ocular dominance
  5. 5Complex cells are less stimulus specific than simple cells and hypercomplex cells are even less specific than complex cells.
    1. AVerdadero
    2. BFalso
  6. 6Drop the type of cell to its description

    These cells respond to a oriented stimulus in a specific location within their receptive fields. [blank_start]Simple Cells[blank_end]

    These cells respond most strongly to oriented lines of specific lengths but respond less to lines longer than that length. [blank_start]Hypercomplex Cells[blank_end]

    These cells will respond to orientations of any length anywhere within their receptive field. [blank_start]Complex Cells[blank_end]

    1. ASimple Cells
    2. BHypercomplex Cells
    3. CComplex Cells
  7. 7Some cells in the V2 may help us to see subthreshold edges by combining signals from hypercomplex cells.
    1. AVerdadero
    2. BFalso
  8. 8Which of the following is an explanation for the tilt aftereffect?
    1. AAfter adaptation to one orientation, that particular cell will temporarily fire less to its usual stimuli, therefore that cell will not contribute as much as it usually would when a new stimulus is presented.
    2. BAdaptations fatigue cells
    3. CMagic
    4. DProlonged exposure to tilted bars makes subsequently seen vertical lines appear tilted in the opposite direction.
    5. EThis occurs as a result of the way the configurations of simple and complex cells are organised.
  9. 9Which of the following would have a low spatial frequency?
    1. AFat stripes
    2. BThin stripes
    3. CBright stripes
    4. DDull stripes
  10. 10Considering the sinusoidal waves for spatial frequency, what part of the wave relates to contrast levels?
    1. AAmplitude
    2. BFrequency
    3. CPhase
    4. DFourier Analysation
    5. EDegrees
    6. FLight reflection
    7. GOrientation
