Identification of Functionally Interconnected Neurons Using Factor Analysis

Figure 2

Neuronal interconnection schemes. (a) are presynaptic neurons. The solid arrows indicate a fixed connection, while dashed arrows indicate the probabilistic connections. These last connections are given between a presynaptic neuron and a pair of recorded neurons. (b) Scheme neuronal interconnections with two layers of presynaptic neurons. Discharges of and neurons are correlated by the discharge of neuron .
