Abstract:                     
      
Synaptic connectivity, expressed as weights of the connections between
neurons, shapes the the activity of neuronal networks, and hence
determine their function. We previously showed that many of these
weights are not at all important to maintain overall stable population
activity. Here I will present three findings on potential functional
consequences of this heterogeneous parameter sensitivity: it enables
optimal encoding of sensory inputs, allows storing memories without
overwriting previous information, and allows targeted pruning of
synapses and neurons during development to build efficient yet highly
functional networks.
