the entropy rate goes way up if you consider spike timing dependent signals as well. but the difference in computational capacity between the brain and ML lies less in the brain's inherently time-dependent dynamics and more in the impressive computational capacity of single neurons. Dendrites compute, electrochemical dynamics during action potentials compute, synapses compute. All in complex time-dependent ways. check out izhikevich's dynamical systems in neuroscience for a taste of the computational capacity of the electrochemical dynamical system alone
