In summary, the available research points to the critical roles of interneurons and inhibition in the formation and segregation of cell assemblies, and in organizing their temporal evolution (c.f., Rabinovich et al., 2006). Given the diverse interneuron classes in the cortex (Freund and Buzsáki, 1996; Klausberger and Somogyi, 2008; Markram et al., 1998), it is expected that further research will identify novel mechanisms by which the different classes interact with each other and the principal cells to choreograph the syntactical structures of externally controlled and internally generated neural sentences.
