Neuronal assemblies are defined as ensembles of coupled neurons [1], where the collective activity of these individual neurons {fact:1, fact:5, fact:7} and their specific connectivity patterns {fact:4, fact:6} form the basis for mental representations.

claimA neural correlate of a mental representation is activated when the neurons forming the assembly operate more actively, such as producing higher firing rates, than in their default mode.
claimThe neural correlate of a mental representation is characterized by connectivities or couplings among neurons that form an assembly confined with respect to its environment, where connectivities are weaker than within the assembly.
claimNeuronal assemblies are difficult to stabilize if the transfer function of individual neurons is strictly monotonic, meaning increasing input leads to increasing output.
claimAccording to standard neurophysiological accounts, mental representations are correlated with the activity of neuronal assemblies, which are ensembles of several thousands of coupled neurons.

claimStable operation of an activated neuronal assembly requires a subtle balance between inhibitory and excitatory connections among neurons.
claimA neuronal assembly representing a mental state is activated when its constituent neurons operate more actively, such as by producing higher firing rates, compared to their default mode.
claimUmezawa’s proposal treats the brain as a many-particle system where the particles are neurons, operating at the level of neuronal assemblies that correlate directly with mental activity.
