Re-evaluating circuit mechanisms underlying pattern separation (2019, neutral): “In this view, neural circuits must learn to encode distinct stimuli with separated trajectories with minimal overlap due to noise or variability (Friedrich and Laurent, 2001; Stopfer et al., 2003; Broome et al., 2006; Shen et al., 2013; Zylberberg et al., 2016; Remington et al., 2018).”
A map of olfactory representation in the Drosophila mushroom body. (2007, neutral): “Since MBs are essential for odor discrimination (Wang et al., 2004; Stopfer et al., 2003; S. Xia and T. Tully, personal communication), we predict that a fly will find it more difficult to discriminate two odorants that are relayed by the PNs to the same class(es) of KCs. Hallem and Carlson (2006)…”
Divisive normalization in olfactory population codes (2010, background): “Many KCs are selective for a particular stimulus, and KCs tend to respond in a binary fashion, firing either zero spikes or just a few spikes (Stopfer et al., 2003; Wang et al., 2004; Turner et al., 2007).”
ROBUST TIMING AND MOTOR PATTERNS BY TAMING CHAOS IN RECURRENT NEURAL NETWORKS (2012, background): “However, more recent theoretical and experimental work has emphasized the importance of dynamic patterns of activity in neural computations (Buonomano and Maass, 2009; Durstewitz and Deco, 2008; Perdikis et al., 2011; Rabinovich et al., 2008; Stopfer et al., 2003).”
Functional analysis of a higher olfactory center, the lateral horn (2012, methodology): “The classifier first generated a template for each odor by calculating the centroid of the vectors from training trials (50% of all trials) and then classified the remaining (test) trials based on Euclidean distance from the two templates (Stopfer et al., 2003).”
A Simple Connectivity Scheme for Sparse Coding in an Olfactory System (2007, background): “…2002; PerezOrive et al., 2002, 2004; DeWeese et al., 2003; Olshausen and Field, 2004; Quian Quiroga et al., 2005) reveal that activity in some neural populations is very sparse, specific (Willmore and Tolhurst, 2001), and in some instances, invariant to low-level features (Stopfer et al., 2003).”
Normalization for Sparse Encoding of Odors by a Wide-Field Interneuron (2011, background): “Because each KC is, on average, connected to about half of its presynaptic population (the projection neurons or PNs) (16), small changes in the PN population’s output could affect the reliability of the KCs’ sparse output (SI 1), inconsistent with experimental observations (11).”
Testing odor response stereotypy in the Drosophila mushroom body. (2008, neutral): “As in the locust (Stopfer et al., 2003), KCs in Drosophila can be odor selective and concentration insensitive (e.g., KC11, odor 5; Figure 3A) or odor and concentration selective (e.g., KC1, odor 8; Figure 3A).”
A theory of multineuronal dimensionality, dynamics and measurement (2017, background): “In many experiments (e.g. in insect [Stopfer et al., 2003, Mazor and Laurent, 2005, Assisi et al., 2007, Raman et al., 2010, Haddad et al., 2010] olfactory systems, mammalian olfactory [Bathellier et al., 2008, Haddad et al., 2010], pre-frontal [Narayanan and Laubach, 2009, Peyrache et al., 2009,…”
