Organization of primary visual cortex
The primary visual cortex (V1) has a highly structured organization, which was largely uncovered by the research of David Hubel and Torsten Wiesel. It represents four main dimensions of visual stimuli:
- Location in the visual field
- Ocular dominance
- Orientation
- Color

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?
