Topic: learning-induced plasticity

There is strong evidence that alterations in the structural and functional properties of synaptic connections during learning are underlying the formation of long-term memories. However, what specific changes in the architecture of the neuronal network are mediated by learning-induced plasticity is still poorly understood. A major limiting factor of current in vivo imaging studies of synaptic dynamics is that typically only at a small number of synapses are assessed in a given animal, typically tens to hundreds. Here, we started to apply longitudinal in vivo two-photon imaging of more than a m
