Layer 5 contains the major projection neurons of the neocortex and is composed of
two major cell types: regular spiking (RS) cells, which have cortico-cortical
projections, and intrinsic bursting cells (IB), which have subcortical
projections. Little is known about the plasticity processes and specifically the
molecular mechanisms by which these two cell classes develop and maintain their
unique integrative properties. In this study, we find that RS and IB cells show
fundementally different experience-dependent plasticity processes and integrate
Hebbian and homeostatic components of plasticity differently. Both RS and IB
cells showed TNF?-dependent homeostatic plasticity in response to sensory
deprivation, but IB cells were capable of a much faster synaptic depression and
homeostatic rebound than RS cells. Only IB cells showed input-specific
potentiation that depended on CaMKII autophosphorylation. Our findings
demonstrate that plasticity mechanisms are not uniform within the neocortex, even
within a cortical layer, but are specialized within subcircuits.
