Processing with cell assemblies

Cell assemblies (CAs) were posited by Hebb almost 60 years ago as the unit of representation in the brain. Recent results in the field of neuroscience indicate that CAs are likely to exist, at least in the mammalian brain. The CABot project uses simulations of CAs formed from individual neurons as a basis for learning and behaviour. This paper proves that a network of CAs, as described by Hebb and as implemented in CABot, is complete with respect to structured program theory. It follows that it is possible to implement the fundamental operations of program execution in a biological network.
