Pavlov’s dog classical conditioning experiment implemented by h-BN-encapsulated MoS2 synaptic transistor. Pavlov’s dog classical conditioning experiments can be simulated on the proposed h-BN-encapsulated MoS2 synaptic transistor by efficient electrical modulation. bg (base, pulse) of (-5, -4 V) applied to the presynaptic gate is considered to be “bell” (NS), and bg (base, pulse) of (-3, -4 V) is considered “food” (US). The postsynaptic source drain channel current acts as synaptic weight, and the synaptic weight of 20 nA is defined as the threshold for the “salivation” response.
