Neuron computation is electro-chemical through voltage gated ion channels. If the voltage is at or below the Landauer voltage, then ion motion through the gate is pure noise. As the voltage climbs above the Landauer limit, you start to get meaningful probabilistic state transitions (error rate below 50%) in reasonable time; you can then implement analog computation using many such unreliable carriers reducing error/noise through central limit binomial.
‘Pure’ chemical computation is protein machinery. Biology evolved voltage based signaling for high speed longer distance communication/computation.
