Perception and its neuronal mechanisms.
A classic view of the relation between sensorineural activity and perception has assumed that the former is somehow transformed into the latter at some locus in the brain. This notion conflicts with the modern view that the activity of the nervous system is restricted to transmitting and processing information. It is suggested that the conflict may be resolved by considering perception as reflective activity rather than passive reception. This cognitive process entails information about the perceiving self and the general context and not merely the stimulus input. Some aspects of perception can be related to neuronal mechanisms and even to neuronal activity at specific loci. How is this done? By identifying the characteristics of the perceptual process and finding a necessary and sufficient neuronal mechanism that receives information about the stimulus input and can perform the implied computation. Examples are taken from the study of visual development in human infants.
