Synaptic crosstalk is common and ubiquitous in the nervous system and it is mainly caused by neurotransmitter spillover between synapses. In this paper, the firing activity of neurons and the collective behavior of a ring thermosensitive neural network with synaptic crosstalk and time delay are investigated. The strength of incoherence and local order parameter are considered. The effects of crosstalk intensity, time delay and external excitation on the responses of the network are explored. As the crosstalk intensity varies, different spatiotemporal patterns come into being, such as chimera and multi-cluster chimera death. In addition, time delay can give rise to the generation and transition of chimera and multi-chimera patterns. Complicated dynamical responses of the network under different external excitations are shown, such as multi-stable motions and quasi-periodic oscillations. The coexistence of chimera, multi-cluster chimera, and complete synchronization states is observed for the network with random initial values.
