Scientific paper

We have designed a toy brain and have written computer code that simulates it. This toy brain is flexible, modular, has hierarchical learning and recognition, has short and long term memory, is distributed (i.e. has no central control), is asynchronous, and includes parallel and series processing. We have simulated the neurons calculating their internal voltages as a function of time. We include in the simulation the ion pumps of the neurons, the synapses with glutamate or GABA neurotransmitters, and the delays of the action pulses in axons and dendrites. We have used known or plausible circuits of real brains. The toy brain reads books and learns languages using the Hebb mechanism. Finally, we have related the toy brain with what might be occurring in a real brain.
