Which of the following is true of "complex" cells within the visual cortex?


AThese cells appear to code for the movement of lines of a particular orientation across their receptive field.
BThese cells respond to a black dot that moves erratically around the visual field.
CThese cells respond to a stationary line of any orientation and possess a strong inhibitory field in part of their receptive field.
DThese cells respond to a stationary line of a particular orientation placed within an excitatory portion of its receptive field.
EThese cells respond to a set of fuzzy parallel lines of low spatial frequency.

Verified Answer :

Final answer:

Complex cells in the visual cortex specifically code for the movement of lines with a particular orientation across their receptive fields. They are distinct from simple cells as they respond to dynamic stimuli rather than static ones. Thus, the correct statement about these cells relates to their response to movement.


Explanation:

Understanding Complex Cells in the Visual Cortex

In the visual cortex, complex cells are a type of neuron that has distinct properties compared to simple cells. These cells are primarily responsive to the movement of lines with a specific orientation across their receptive fields. Unlike simple cells, which respond best to static stimuli, complex cells integrate information over a larger area of the visual field.

To elaborate, complex cells respond optimally when a line of a certain orientation moves through their receptive field in a specific direction. This coding for movement is crucial for processing dynamic aspects of the visual environment. Therefore, the first option stating that 'These cells appear to code for the movement of lines of a particular orientation across their receptive field' accurately describes the characteristics of complex cells.

Why Other Options Are Incorrect

  • The second option regarding a black dot moving erratically does not capture the main function of complex cells.
  • The third option suggests that these cells respond to stationary lines, which aligns more with simple cells.
  • The fourth option, which talks about a stationary line placed in an excitatory region, also describes simple cell behavior.
  • Finally, the fifth option regarding fuzzy parallel lines is not representative of how complex cells function.
