abstract = {The neocortex, and with it the mammalian brain, achieves a
level of computational efficiency like no other existing
computational engine. A deeper understanding of its building
blocks (cortical microcircuits), and their underlying
computational principles is thus of paramount interest. To
this end, we need reproducible computational models that can
be analyzed, modified, extended and quantitatively compared.
In this study, we further that aim by providing a
replication of a seminal cortical column model. This model
consists of noisy Hodgkin-Huxley neurons connected by
dynamic synapses, whose connectivity scheme is based on
empirical findings from intracellular recordings. Our
analysis confirms the key original finding that the
specific, data-based connectivity structure enhances the
computational performance compared to a variety of
alternatively structured control circuits. For this
comparison, we use tasks based on spike patterns and rates
that require the systems not only to have simple
classification capabilities, but also to retain information
over time and to be able to compute nonlinear functions.
Going beyond the scope of the original study, we demonstrate
that this finding is independent of the complexity of the
neuron model, which further strengthens the argument that it
is the connectivity which is crucial. Finally, a detailed
analysis of the memory capabilities of the circuits reveals
a stereotypical memory profile common across all circuit
variants. Notably, the circuit with laminar structure does
not retain stimulus any longer than any other circuit type.
We therefore conclude that the model's computational
advantage lies in a sharper representation of the stimuli.},
