6. How neurons decode the signal? The brain contains a network of ~ 10 10 interconnected neurons. In every small volume of cortex, thousands of spikes are emitted each millisecond. What is the information contained in such spatio-temporal pattern of pulses? What is the code used by the neurons to transmit that information? How might other neurons decode the signal?
