A phototube can capture the external light signal, and it can convert light signals into electrical signals. Therefore, a phototube connected to a neural circuit can simulate the eyes of animals. In this work, a nonlinear circuit is constructed by resistance-coupling two capacitors, and then a photosensitive neuron with linear membrane is proposed by embedding a phototube into the nonlinear circuit. Here, a Josephson junction is used to describe ion channel in the biological neuron, and photocurrent of a phototube is applied to adjust the output of the neural circuit. Furthermore, a parameter adaptive growth method for energy control is designed for exploring the self-regulation and adaptive properties of biological neurons. The numerical results illustrate that the complex firing modes of a photosensitive neuron with linear membranes can be formed by adding the different intensity of the external light signal, and the electrical activities of a functional neuron with a Josephson junction ion channel can be adaptive adjusted using the adaptive growth method for energy control. In addition, the stochastic resonance can also occur under certain noise intensity. This work is used to investigate the collective behaviors in the network is coupled by the photosensitive neuron with linear membranes.
