Columns and Hypercolumns in the Visual Cortex
A key discovery by Hubel and Wiesel was the highly organized arrangement of neurons in the visual cortex. They found that cells with similar response properties, such as reacting to the same line orientation, are grouped together into vertical structures known as columns. These columns are further organized into larger processing units called hypercolumns.

Columns and Hypercolumns in the Visual Cortex
Imagine a neuroscientist inserts a microelectrode perpendicularly into the surface of the primary visual cortex. As the electrode is slowly advanced, it records the activity of several neurons that lie in a direct line, one after the other. All of these neurons are found to be responsive to stimuli presented in the exact same small area of the visual field. Which of the following additional properties would this specific group of neurons most likely share?
