Scientific Understanding of Consciousness
Consciousness as an Emergent Property of Thalamocortical Activity


Visual perception is formed in a hierarchy of neuronal assemblies extending from the primary visual areas of posterior cortex, through the association areas of parietal cortex, the interpretive areas of temporal cortex, and into the frontal cortex. Perception is associated with sparse but widespread neural activity in the higher levels of the ever widening receptive fields this visual hierarchy. Visual memory is mediated by synaptic plasticity in the sparse but widespread neural activity patterns in the higher association cortex.

Audition and Speech

Hierarchy of three pathways in series through which auditory information passes on its afferent journey through the CNS. (1) Reticular formation,  (2) Thalamus, (3) Cortex.  (Schneck & Berger; Music Effect, 86)

Research Study — Sense of Touch


Pain Neural Pathways diagram






Taste and olfactory inputs converge in the orbitofrontal cortex of the frontal lobes, producing in a subjective flavor representation.

Flavor representation -- of taste and olfactory inputs in. (Rolls; Memory, Attention, and Decision-Making, 151)


Convergence-Divergence Zones and Working Memory

The association cortex areas of sensory processing will involve the functionality of Damasio's Convergence-Divergence Zone architecture.

The working memory model of Baddeley will function together with Fuster’s Perception-Action Cycle.
