The question is what is the human brain? Is it an analog or digital form of wetware?
The question has been repeatedly asked since the time Charles Babbage invented the first primitive form of computer. Is the human brain analog or digital?

Well, it is neither. It instead works as a signal processing model. Yet it does have certain properties in common with both analog computers and digital computers.
While it does not employ binary logic, memory or arithmetic, information is represented in the form of statistical heuristics rather than strict measures.
As for the free will of the brain, it is a sure thing. It is in no way deterministic. Thus the brain is not digital. Yet the either/or decision-making of the brain resembles binary logic, according to Forbes.
A neuron which is the basic unit of the brain will either fire or not fire. These form the basic linguistic capacity of the brain. Also within neurons are biochemical pathways.
These on the contrary behave like analog systems. The neural spiking of the brain resembles digital signaling. The brain thus uses a different type of computational skill toolkit.
The brain is said to be a wonder and a marvel of existence. The number of neurons in the human brain are said to exceed the number of stars in the universe.
It is a billion dollar computer that can solve the most complex of problems and reach insights that other animals and species cannot even conceive of in their wildest dreams.
While it has its disorders and glitches, the genius it shows has enabled human beings to become the dominant species on the planet earth. The brain’s evolution will hopefully allow mankind to escape from the mess it finds itself in at present.
