Explain in your own words why simple cells in V1 give larger responses when the bars are parallel to the axis of elongation than
abruzzese [7]

Answer: This is as a result of it covering more on the center part of the cell unlike when it is perpendicular.

Explanation: This is as a result of it covering more on the center part of the cell unlike when it is perpendicular. Cells in the primary visual cortex tends to responds to a particular direction of light. There are distinct inhibitory and excitatory regions and when the bar of light is moved over the cell you hear the firing rate (noise) which depends on the direction the light moves in. When the bar of light is set at an angle or perpendicular, the inhibitory receptive field is illuminated which slows the firing rate. when the bar of light is perpendicular, it leads to both the inhibitory and excitatory regions being illuminated which can sometimes result in their firing potentials canceling out each other, which can lead to no response in firing.
