I am writing a book about anatomically plausible superhumans ( a new artificially created form of man ), which, in addition to incredible physical strength, should also be distinguished by incredible intelligence, which I have always tried to increase simply by making their brains larger or compacting the neurons themselves, as is the case in birds. However, some time ago I thought about why not transfer some of the functions into the cell itself, creating a primitive computer from each neuron?
So in binary computers we can only pass or delay one signal, depending from the other. We use Boolean algebra and logic for addition. At the same time, an analog computer can fold natively. Gapless synapses (a design of neurons invented by me that might not have a gap between synapses) already know how to amplify or jam a signal, and we just need to add signals to each other and change their total power according to a given coefficient. How should such modified neurons be arranged?
Unlike ordinary human neurons, inside this neuron there should be thin branching tubes, divided into sectors. Sectors of these villi could connect, amplify and separate the signal, form direct and feedback stations, and pass the impulse in only one direction. In this case, the tubes themselves would have to be filled with chemically obtained ions, which would regulate the electrical resistance of the medium. Depending on the potential of the pulse, the conductivity can change, which changes the power of the signal at the output. The signal would have to be added if the two tubes are connected together. The signal that passes more often stimulates an increase in the channel conductance, which amplifies it at the output. Thanks to external signals, it is possible to change the conductance of individual channels, which makes it possible to change the weight of the entire neuron. As a result, such cells should have become larger, but a network of ten such analog neurons could replace a network of a thousand ordinary ones.
How scientifically realistic is this design of neurons of my superhumans and how much, if it is possible to calculate, ordinary people could become smarter with such an addition in the nervous system?
