mushroom body

ID: FBbt_00005801

Bilaterally paired neuropil structure situated postero-dorsally in the protocerebrum that functions in olfactory associative learning and memory. The mushroom body is divided into: the calyx, which is closest to the cortex and receives sensory interneuron afferents; the pedunculus, which is a thick axon bundle extending from the calyx to the base of the lobes; and the mushroom body lobe system, which consists of a vertical branch and a medial branch, which have different structures at different life stages (Lee et al., 1999; Ito et al., 2014).

This term as defined in Ito et al. (2014) corresponds to both the mushroom body (MB) and calyx (Cal) of Chiang et al. (2011).
