Diagram showing how the location of the percept can be different from the location of origin of the sensory stimulus. This is demonstrated using the experiment of refraction of light at the water–air interphase. Please rotate this page anticlockwise to view the formation of perceptons (modified from Fig. 4). XY is a rod placed in water. The perceived bent segment of the rod is shown as pq. Based on explanations in optics, the incident ray of light (afferent path) bends at the junction between water and air. However, there are no explanations how the efferent path of perception of the rod at pq occurs. Based on the present work, the perceptons (net semblions from both sides of an inter-postsynaptic functional LINK) get projected in straight lines outside the nervous system (Note that this is a description of the quality of the virtual internal sensation). The directions of the stimuli and semblances are opposite to each other. Note that for simplicity, the semblions are drawn to a single point in contrast to their expected spanning over several sensory receptors as in the original derivation (Vadakkan 2013) and shown in Figs. 3, 4 above. {srp1}: Sensory receptor set1; {srp2}: Sensory receptor set2; AB and CD synapses; BD inter-postsynaptic functional LINK; {sr1}: sensory receptor set through which semblion1 is induced. {sr2}: sensory receptor set through which semblion2 is induced. 1,2,3,4: Neuronal orders. W oscillating potential that has horizontal component contributed by the lateral spread of activity through the inter-postsynaptic functional LINK BD
