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.

Definitions:

T Test

A statistical analysis method that evaluates if there's a significant difference between the average values of two distinct groups.

Null Hypothesis

A hypothesis that suggests there is no statistical significance in a set of given observations, serving as a default position until evidence suggests otherwise.

Research Hypothesis

A specific, testable prediction about the outcome of a scientific study based on theory or prior research.

Significance Level

The threshold at which the results of statistical analysis are considered statistically significant, commonly set at α = 0.05 or 5%.
