Any such estimated relation would be worthless because of the analog/digital nature of neurons and their ability to adapt to stimuli or input. Transistors lack the ability to adapt to stimuli. Another problem with such an estimate would be the difference in bandwidth between neurons and transistors. Transistors are much faster switchers than neuron, having a bandwidth of around 100 Mbaud. Neurons are limited to about 300 action potentials per second.
