Re-evaluating circuit mechanisms underlying pattern separation (2019, neutral): “Global feedback inhibition is provided by a single GABAergic neuron, called the anterior paired lateral (APL) neuron in Drosophila, which is both presynaptic and postsynaptic to virtually all Kenyon cells (Leitch and Laurent, 1996; Liu and Davis, 2009; Papadopoulou et al., 2011), although recent evi”

Are mushroom bodies cerebellum-like structures? (2011, background): “, 2010); the mushroom bodies are also innervated by GABAergic neurons in addition to those providing inputs to the calyces, but little is known of their synaptic connections outside of the mushroom bodies (Leitch and Laurent, 1996; Yamazaki et al., 1998; Bicker, 1999; Schürmann et al., 2009).”
Synaptic organization of the mushroom body calyx in Drosophila melanogaster (2002, background): “First we confirm for Drosophila the divergent output of PN boutons, already demonstrated for all insect species previously investigated at the ultrastructural level (e.g., Schürmann, 1974; Leitch and Laurent, 1996; Sun et al., 1997; for reviews, see Schürmann, 1987; de Belle and Kanzaki, 1999).”
Evolution of insect mushroom bodies: old clues, new insights (2005, background): “Electron microscopic evidence suggests that information flow in these neurons is mostly, but not always, from the lobes to the primary calyces (Leitch and Laurent, 1996; Ganeshina and Menzel, 2001).”

Normalization for Sparse Encoding of Odors by a Wide-Field Interneuron (2011, background): “We conclude that GGN receives direct input from the KC population, that GGN is an inhibitory neuron (consistent with its GABAimmunoreactivity (17)), that it releases neurotransmitter in a graded manner, and that GGN is itself reciprocally connected to a spiking inhibitory interneuron.”

Functional analysis of a higher olfactory center, the lateral horn (2012, background): “They also noted that dendrites of KCs intermingle with GABAergic fibers in the calyx region of the MB (Leitch and Laurent, 1996) and that KCs show odorelicited IPSPs.”

A connectome of a learning and memory center in the adult Drosophila brain (2017, background): “Previous EM studies in the MB lobes of cockroaches (Mancini and Frontali, 1970, Mancini and Frontali, 1967), locusts (Leitch and Laurent, 1996), crickets, ants, honey bees (Schürmann, 1974, 2016) and Drosophila (Technau, 1984) identified KCs by their abundance, fasciculating axons and small size.”
