A New Marriage of Brain and Computer - Google Tech Talks September, 21 2007.
ABSTRACT: Brain and computer were wed mid-twentieth century by the McCulloch-Pitts model neuron and Hodgkin-Huxley equations for digital firing in biological neurons. Since then, brain neurons, synapses, firings and networks have been considered analogous to electronic switches, states and circuits in classical computers. But despite extraordinary advances and bold predictions, consciousness seems ever more elusive.
