The smaller the receptive fields in a region, the greater the density of receptors in that region, which leads to greater acuity in the region. This is because the smaller receptive fields allow for more precise localization of stimuli, requiring a higher density of receptors to achieve this precision. Additionally, the increased density of receptors in the region may result in more cortical space allotted for sensory reception, although this is not always the case. Thus, the best choice is E, as it accurately reflects the relationship between receptive field size, receptor density, and acuity.
