Ghost Resonance in Hodgkin-Huxley Neurons

Abstract

Studies have shown that neurons exposed to two or more signals with different frequencies can fire at frequencies other than these. This phenomenon is known as Ghost Resonance (GR). In this study, GR phenomenon was investigated in a two-layer feed forward loop (FFL) network consisting of Hodgkin-Huxley (H-H) neurons. Periodic signals with different frequencies were applied to each of the two neurons in the first layer of the FFL network. The firing behavior of the neuron in the second layer of the FFL network has been studied. The results show that the third neuron in the FLL network fires at a frequency that is the absolute value of the difference between the frequencies of the signals applied to the first and second neurons. These results reveal the presence of GR phenomenon in H-H neurons.
