Electric
circuits in the cortex (cont.)
•A single neuron is capable of an astonishing assortment of very complex operations, far exceeding the
capabilities of the simple
ALU’s at the heart of the VNA.
•Further, much of the complexity comes from the action in
the synapes, of which there can be
~6000 in a single neuron. These synapses are very small, and each one has computational capabilities still under heavy investigation.
•So, don’t believe the predictions of computers exceeding
the ability of the brain in the next
few years. These sorts of predictions way underestimate the MIPS rating of a single neuron.
