Brain emulators are being perfected at Stanford University where NeuroCore chips are ganged together for any sized NeuroGrid--or artificial brain. Emulators-as opposed to mere simulators--use hardware, here mixed signal NeuroCore chips that emulate the ion-channel and firing behavior of real neurons in realtime--aproximately the same amount of time used by reals brains; R. Colin Johnson @NextGenLog
The Neurocore tile contains four synaptic population circuits, four ion channel population circuits, a dendritic compartment circuit and a somatic compartment circuit. A Neurocore has 256-by-256 of these tiles.
he Neurogrid board uses 16 Neurocore chips to simulate one million neurons with six billion synaptic connections
