Figure 13: Mushroom body neurons respond to a variety of sensory modalities. This figure shows a selection of responses from afferent neurons to the cockroach calyces (A) and efferent neurons in the medial lobes supplying the superior lateral protocerebrum (B, C). As shown in B, combinations of stimuli are more effective than unimodal stimuli in eliciting a response from efferent neurons. There is no response to light ON, a weak response to acoustic stimulation, but when both are combined there is vigorous activation of this neuron. In C, an efferent neuron from the medial lobe to the inferior medial protocerebrum is inhibited by acoustic stimuli after presentation of visual and olfactory cues (top trace, C) but the same neuron is excited by sound after flicker and tactile cues.
