Hubel and Wiesel Identified Simple Cells and Complex Cells in the Visual

question 5

Multiple Choice

Hubel and Wiesel identified simple cells and complex cells in the visual cortex. Simple cells respond to bars of light in a particular orientation. For example, stimulation by a bar of light in the center of the visual field could excite the V1 neuron but moving the bar of light to either side of the center will inhibit the neuron. What anatomical structure did Hubel and Wiesel propose that would confer this response on the V1 neuron?

• A) The receptive field of the simple cell is the result of input from many complex cells within the visual cortex.
• B) The receptive field of the simple cell is the integration of inputs from many LGN neurons that have OFF-center/ON-surround responses.
• C) The receptive field of the simple cell is the integration of inputs from many LGN neurons that have ON-center/OFF-surround responses.
• D) The receptive field of the simple cell reflects complex processing in cortical microcircuits.
