3.Describe the differences between the neural and computational processing of visual and auditory stimuli at the receptor level and at the level of the primary sensory cortex. In your answer, you could consider the differences of the type of physical energy processed in the two modalities, the organisation and structure of the relevant neural receptor and cortical areas, the maimer in which these relevant neural receptors and cortical areas respond to regarding these energy modes, the resulting properties, limitations，capabilities of the respective cognitive representations.
