Figure 51. — (A) Type-to-type connectivity matrices showing the neuron types targeted by each of the sleep-wake neuron types. The downstream neurons are divided into groups, with non-FB tangential targets shown in the top panel and FB tangential targets shown in the bottom panel. Green text marks neurons involved in ellipsoid body-FB (EB-FB) sleep-wake circuit (see Figure 53). Connections with relative weights below 0.005 were excluded from this analysis. (B) Number of synaptic connections from each sleep-wake neuron type to other FB neuron types (tangential or columnar), neuron types with prominent arbors outside the FB (EB/bulb [BU], superior protocerebrum SMP/SIP/SLP, lateral accessory lobe [LAL], crepine [CRE], and olfactory), or unknown types (i.e., neurons that have not been assigned a type name). (C) Same as in (B) but plotting the number of downstream neuron types reached.
