Birth and death of spiral waves in a network of Hindmarsh–Rose neurons with exponential magnetic flux and excitable media

作者：

Highlights：

• An improved Hindmarsh–Rose model with external electromagnetic radiation and discontinuous exponential flux coupling is introduced.

• We propose a two-dimensional network of such Hindmarsh–Rose neurons.

• The spatiotemporal patterns of the network in different cases are presented.

• The effective factors on the formation of spiral waves are investigated.
