Re-evaluating circuit mechanisms underlying pattern separation (2019, neutral): “Anatomical estimates of the ratio of projection neurons to Kenyon cells in the mushroom body are roughly 1:40 (Laurent, 2002; Litwin-Kumar et al., 2017).”
Mushroom body output neurons encode valence and guide memory-based action selection in Drosophila (2014, background): “Moreover, long-term synaptic depression is known to occur in the granular cell synapses to Purkinje cells in the vertebrate cerebellum (Ito et al., 1982), a local neuronal circuit with many analogies to the MB (Schurmann, 1974; Laurent, 2002; Farris, 2011).”
The neuronal architecture of the mushroom body provides a logic for associative learning (2014, background): “The MB may therefore represent an evolutionary primitive brain structure homologous in form and function to structures in the vertebrate brain (Schurmann, 1974; Laurent, 2002; Tomer et al., 2010; Farris, 2011).”
Optimal synaptic learning in non-linear associative memory (2010, background): “They exist both in a hetero-associative feed-forward form storing the mapping between the address memories uµ and the associated content memories vµ, but also in an auto-associative recurrent form where address and content memories are identical, where typical tasks include denoising and pattern…”

Normal and pathological oscillatory communication in the brain (2005, background): “The interactions between the antennal lobe, the mushroom body and the inhibitory neurons in the lateral horn are of particular interes”
Organization and evolutionary trends of primary olfactory brain centers in Tetraconata (Crustacea+Hexapoda) (2005, background): “sexta showed that GABA is generally involved in inhibitory interactions needed for odor evoked synchronization of PN activity (reviewed by Boeckh and Tolbert, 1993; Laurent, 2002; Lei et al., 2002; Sachse and Galizia, 2002) and for interglomerular inhibition (Lei et al.”
Feed-Forward versus Feedback Inhibition in a Basic Olfactory Circuit (2015, background): “Sparse codes support learning and memory by reducing interference between memory traces, increase storage capacity, and save energy expended by action potentials [16, 18, 50, 51].”
Functional analysis of a higher olfactory center, the lateral horn (2012, methodology): “It remains possible the LH could mediate innate behaviors through specifically tuned neurons we did not observe, by responding preferentially to categories of odors we did not test, or through another mechanism such as the combinatorial coding scheme used by PNs (Laurent, 2002).”
Optimal dynamical range of excitable networks at criticality (2006, result): “This transient behaviour is reminiscent of oscillations widely observed in experiment”
Divisive normalization in olfactory population codes (2010, background): “Circuit Mechanisms: Connectivity between Glomeruli It is generally thought that specific connectivity between glomeruli is important for olfactory processing (Laurent, 2002; Lledo et al., 2005).”

(2011, background): “…processing (Perez-Orive et al., 2002; Szyszka et al., 2005; Ito et al., 2008; Turner et al., 2008), where Kenyon cells have been proposed to transform olfactory inputs into a sparse codeperhaps as aprerequisite for encodingodorant identity for memory storage (Laurent, 2002; Luo et al., 2010).”
