Drawing on this development, this chapter analyses perceptions as processes. In neural network models the brain is said to cope with the plethora of sensory information by predicting stimulus regularities on the basis of previous experiences. These biases are increasingly studied as constitutive factors of brain processes in recent neuroscience. The problem for this view concerns perceptual biases as responsible for distortions and the subjectivity of perceptual experience. How much does stimulus input shape perception? The common-sense view is that our perceptions are representations of objects and their features and that the stimulus structures the perceptual object. Such instances pose a kind of 'binding problem' in which participating individuals exhibit a degree of 'entanglement'. Combining these ideas with social mirror theory it is not difficult to imagine the creation of similar dynamical patterns in the emotional and even cognitive neuronal activity of individuals in human groups, creating a feeling in which the participating members experience a unified sense of consciousness. Though not without criticism, Menant has made the case that mirror-neuron assisted exchanges aided the original advent of self-consciousness and intersubjectivity. Many authors have considered the likely role of such mirror systems in the development of uniquely human aspects of sociality including language. There are also mirror neurons in the anterior insula and anterior cingulate cortices which have been implicated in empathy. Mirror neurons in the premotor and posterior parietal cortices respond to the intentions as well as the actions of other individuals. This paper discusses supportive neurological and social evidence for 'collective consciousness', here understood as a shared sense of being together with others in a single or unified experience.
