Modulation of Coordinated Activity across Cortical Layers by Plasticity of Inhibitory Synapses (Cell Reports)

Lourenço et al. demonstrate that burst firing of layer 5 pyramidal neurons (PNs) induces long-term potentiation of inhibition (LTPi). LTPi strongly affects PN input/output spikes, prevents transfer of information across cortical layers, and affects phase locking of PN firing to cognition-relevant rhythmic activity.
