An Electronic Circuit Model of the Interpostsynaptic Functional LINK Designed to Study the Formation of Internal Sensations in the Nervous System

Figure 7

Comparative diagrams showing interpostsynaptic functional LINK and its corresponding electronic circuit at the time of both formation and reactivation of the interpostsynaptic functional LINK. (a) Schematic diagram showing a comparison between a neuronal circuit (above) and the corresponding electronic circuit (below) showing the formation of a functional LINK between the postsynaptic terminals at the time of associative learning. Simultaneous activation of abutted postsynapses results in interpostsynaptic functional LINKs which is modelled using the latch that can be controlled through a timer. The detailed electronic circuit is shown in Figure 8. N_A and N_C are presynaptic neurons. Cell bodies of postsynaptic neurons are not shown. Synapses are marked as [] and []. Outputs occur through both the output terminals (dendrites from both and ). (b) A schematic diagram showing a comparison between a neuronal circuit and the corresponding electronic circuit showing the reactivation of the interpostsynaptic functional LINK by the cue stimulus arriving at neuron N_A at the time of memory retrieval. Two major changes are expected to occur at this time as a systems property. These include (A) semblions getting induced at the cathode of the diode located immediately after the comparator N_C and (B) activity then spreading to the postsynapse . : postsynapse of the neuron N_A. : presynapse (axonal terminal) of the neuron N_A. : postsynapse of the neuron N_C. : postsynapse of the neuron N_B (not shown). : postsynapse of the neuron N_D (not shown). IPS: interpostsynaptic functional LINK. Den: dendrite. During associative learning simultaneous activation of abutted postsynapses.
