We explore the dynamics of an adiabatic neural cell of a perceptron artificial neural network in a quantum regime. This mode of the cell operation is assumed for a hybrid system combining classical neural network having configuration dynamically adjusted by a quantum co-processor. Analytical and numerical studies take into account non-adiabatic processes, as well as dissipation, which leads to smoothing of quantum coherent oscillations. The obtained results indicate the conditions under which the neuron possesses the required sigmoid activation function.
