Network architecture.

A symbolic diagram of the network architecture for the virtual experiment. The input layer, which provides learning signals, recall cues, and distractors in the form of spikes, and its (feedforward) connections to the main network are shown in blue. The excitatory portion of the network and its associated excitatory connections (both recurrent and feedforward) are shown in green. The inhibitory portion of the network and its associated inhibitory feedback connections are shown in red.
