Simultaneous learning of two inhibitory profiles via Hebbian and anti-Hebbian plasticity rules. A, Temporal evolution of inhibitory synaptic weights when one inhibitory population follows a Hebbian plasticity rule (top), and the other population follows an anti-Hebbian plasticity rule (bottom). B, Initial (top) and final (bottom) weight profiles from A, with excitatory weights for reference. C, Individual synaptic weights before and after learning for synapses following the Hebbian plasticity rule (top) and synapses following the anti-Hebbian plasticity rule (bottom).
