Switchable regulation plays an important role in information encoding in the nervous system. An appropriate level of chaotic activity can enhance the encoding of weak signals in neurons, the phenomenon known as chaotic resonance (CR). However, previous studies of CR focused on single neurons without polymodal network. Therefore, to investigate how chaotic activities of switchable regulation affect the transmission of weak signals and neuronal synchronization across multi-mode pathways, this paper proposes a polymodal auditory network, with communication function combining auditory neurons and central neurons. It is shown that regardless of the currents, electric fields, and magnetic fields, chaotic activity can effectively enhance the information transmission between neurons. The enhancement regulation of CR in information transmission is realized by controlling signal frequency and current intensity, regulating multi-mode pathways. Furthermore, the enhancement of phase synchronization in polymodal auditory networks by chaotic activities is revealed, and synchronization and de-synchronization between neurons can be achieved through the adjustment of relevant parameters or the switching of pathways. The research offers insights into how chaotic activities influence information transmission and phase synchronization within neural systems, and provides guidance for the switchable regulation of artificial biological synapses and the polymodal development of brain–computer interfaces.
