Functional connectivity between CS-excited neurons and CS-inhibited neurons in the BAL. (a) Types of functional connectivity between CS-excited neurons and CS-inhibited neurons (left), between conditioning-potentiated neurons and CS-inhibited neurons (right). (b, d, f) Z-score cross-correlograms between CS-inhibited neurons and extinction-resistant neurons (b; n = 8, 61% of CS-excited and CS-inhibited neuronal pairs, extinction-resistant neurons as references and CS-inhibited neurons as targets), between CS-inhibited neurons and fear neurons (d; n = 2, 16%, fear neurons as references), and between a CS-inhibited and an extinction-potentiated neuron (f; n = 1, 8%, extinction-potentiated neuron as a reference). (c, e, g) The distribution of the time of significant peaks in cross-correlograms for the pairs between CS-inhibited neurons and (c) extinction-resistant neurons, (e) fear neurons, and (g) extinction-potentiated neurons. CS-inhibited neurons tend to fire before than extinction-resistant neurons and fear neurons in the pairs.
