Synchronization of Neuronal Circuits with Ring Connection on PSpice

الملخص EN

The modes of electric activities in neurons and wave propagation between neurons can be changed by using appropriate external forcing or coupling type.

Based on the PSpice tool, the coupling synchronization between three Hindmarsh-Rose neurons is investigated.

The neuronal circuit is also designed, and the Schmitt trigger circuit is used as peak detector by transmitting the analog signal into digital signal; thus, the rhythm of electric activities of neurons can be analyzed.

By selecting different initial states (spiking or bursting), different synchronization states are found.

In the case of spiking state, appropriate coupling intensity is effective in realizing rhythm synchronization and then homogenous state is observed by further increasing the coupling intensity.

In the case of bursting state, rhythm synchronization is enhanced under appropriate coupling intensity while desynchronization occurs by further increasing the coupling intensity.
