Local and Global Gating of Synaptic Plasticity

The document describes a neuronal model that investigates local and global mechanisms of synaptic plasticity. The model includes input, excitatory, and inhibitory neurons fully connected in layers. Trial I presents stimuli randomly to form local representations, while Trial II pairs one stimulus with basal nucleus activity to modify representations globally. Experimental results show that without basal activity in Trial I, neurons largely form specific local representations of stimuli.
