Neuronal circuits in the mammalian brain are capable of
receiving and storing inputs from the external world. Over the
last century, theoretical predictions and experimental evidence
have converged to indicate that sparse populations of neurons
are responsible for encoding stimuli or behaviours. Prominent
theories, most notably those of D. Hebb, have also indicated how
information could then be recalled from these populations, or
‘assemblies’, of neurons. In particular, re-activation of just
part of an assembly would selectively activate the rest of it
and ultimately lead to recall of the stored stimulus or
behaviour. However, no direct experiment
