The receptive fields in the primary visual cortex (V1) are smaller than in the visual association areas, such as V2 and V3. This is because V1 neurons receive input primarily from the retina, while the visual association areas integrate information from multiple sources and have larger receptive fields. Therefore, V1 neurons have more selective and precise responses to visual stimuli, while the visual association areas are responsible for more complex processing and higher-level visual perception.
