Summary:
Neuron in the cerebral cortex, which is said that a more higher-order function is governed, emits spikes very irregularly with low reliability. The question of why the brain works elaborately though such a seemingly probabilistic vague neurons has been studied for a long time. In this study, we study the effect of noise and oscillatory inputs from the aspect of neuronal reliability which is observed through Fano factor and investigate their roles in neural coding. We show that the noise switches its coding performance depending on the amplitude of oscillatory inputs.
