Long-term synaptic potentiation (LTP) is thought to be a key process in cortical synaptic network plasticity and memory formation. Hebbian forms of LTP depend on strong postsynaptic depolarization, which in many models is generated by action potentials that propagate back from the soma into dendrites. However, local dendritic depolarization has been shown(More)
Functional maps in the cerebral cortex reorganize in response to changes in experience, but the synaptic underpinnings remain uncertain. Here, we demonstrate that layer (L) 2/3 pyramidal cell synapses in mouse barrel cortex can be potentiated upon pairing of whisker-evoked postsynaptic potentials (PSPs) with action potentials (APs). This(More)
During development, thalamocortical (TC) input has a critical role in the spatial delineation and patterning of cortical areas, yet the underlying cellular and molecular mechanisms that drive cortical neuron differentiation are poorly understood. In the primary (S1) and secondary (S2) somatosensory cortex, layer 4 (L4) neurons receive mutually exclusive(More)
In this issue of Neuron, Chen et al. (2012) and van Versendaal et al. (2012) used fluorescently tagged gephyrin to track inhibitory synapses in the mouse visual cortex in vivo. Their studies show that visual experience-dependent plasticity is associated with clustered and location-specific pruning of inhibitory synapses.
