Questions and Answers

What is the receptive field?

  • A small area of the retina where light shone upon will increase the firing of receptive cells. (correct)
  • A small area of the retina where signals sent from onlythe retinal ganglion cells will increase the firing of cells
  • A large area of the retina where light shone upon will increase the firing of receptive cells.
  • An area of the retina where light shone upon it will not activate cells in the retina.

    • Which one of these does not occur when light enters the eye?

  • 1) Rods & cones convert light energy into electrical activity
  • 2) Electrical activity passes through network of cells
  • 3) The cells convert electrical activity back into light energy (correct)
  • 3) The Retinal Ganglion cells sends signals to the optic nerve

    • The neuromuscular junction connects the

  • Eyes and the brain
  • Brain and the limbs (correct)
  • Brain and the spine
  • Eyes and the fingertips

    • Sensory adaptation is useful to enhance sensitivity across a wide range of input intensities

    Study Notes

    Receptive Field and Visual Processing

    • The receptive field refers to the specific region of the visual field that a neuron responds to.

    Light and Eye Function

    • When light enters the eye, the following do not occur: ( wait for the next question to provide the correct answer)

    Neuromuscular Junction

    • The neuromuscular junction connects the neuron to the muscle.

    Sensory Adaptation

    • Sensory adaptation is useful for enhancing sensitivity across a wide range of input intensities.

    Visual Areas and Motion

    • V5 responds to complex motion patterns.
    • V6 responds to (wait for the next question to provide the correct answer).
    • The visual area that does NOT function in motion is (wait for the next question to provide the correct answer).

    Motion Development and Perception

    • Apparent motion is perceived in area V5.
    • Sensitivity to motion develops after birth, except for looming stimuli (things that might collide with the child), which may be present at birth.
