Fig. 1.6 also reveals some secrets of the effective biological computing.
biology makes the ”weighted summing” of neuron’s synaptic inputs simultaneously, in one single operation making multiplication and integration, furthermore selecting the time window and its effective synaptic inputs
the heavily used neuronal information ”is stored, as it should be, in every circuit” [144]
”information stored directly at a synapse can be retrieved directly” [144]
part of the information (in ’volatile’ memory) is stored only for the period when it might be needed (a real temporary cache)
”Computing” is much shorter than ”Delivering”
asynchronous; the operation time varies (no pipelining)
”Send only information that is needed, and send it as slowly as possible” [144]
using voltage temporal gradients enables transferring more information and functionality; for example, synchronization [63]
for simulation: there is no need to send and integrate spike shapes, only the time of arrival/sending
