Re-evaluating circuit mechanisms underlying pattern separation (2019, positive): “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).”
Neuronal pattern separation in the olfactory bulb improves odor discrimination learning (2015, unknown): “Starting from this point, four injections were done in the following order: (1) AP: +500 μm, DV: −1000 μm; (2) +300 μm, DV: −1300 μm; (3) +100 μm; DV: −1400 μm; (4) +100 μm; DV: −2000 μm.”

Timescale-dependent shaping of correlation by olfactory bulb lateral inhibition (2011, background): “Olfactory bulb inhibition is important for behavioral discriminations, particularly between highly similar stimuli that elicit overlapping patterns of activity (6, 7, 12, 44) (for example, two mixtures containing the same odorants at slightly different ratios).”
Maturation and Death of Adult-Born Olfactory Bulb Granule Neurons: Role of Olfaction (2002, background): “Granule cells are known to extensively shape mitral cell response to odors (Yokoi et al., 1995), and there is evidence that the OB circuitry does maximize differences in odor representations (Friedrich and Laurent, 2001).”
Theta oscillation coupled spike latencies yield computational vigour in a mammalian sensory system (2003, methodology): “However, due to the comparatively slow dynamics of odour stimuli it has also been suggested that time could be used as a computational variable for odour representation (Laurent, 1999; Friedrich & Laurent, 2001).”

Encoding and decoding of overlapping odor sequences. (2006, unknown): “Our recent work on insects and fish olfactory systems shows that odors give rise to very different response profiles in two structures separated by only one synapse ( Friedrich and Laurent, 2001; Mazor and Laurent, 2005; Perez-Orive et al., 2002).Inthelocust antennallobe,odors arerepresented by dis”
Neurogenesis Drives Stimulus Decorrelation in a Model of the Olfactory Bulb (2012, background): “stimuli; they may interfere with the performance of the network. The resilience R12 of the granule cells in population n12 is comprised of two large contributions due to the strong inputs in stimuli S(1) and S(2) and two small contributions from stimuli S(3) and S(4), while the resilience R13 of the”
Olfactory information processing in Drosophila. (2009, unknown): “receptor neurons [88]; although a direct comparison has not been made in locusts [91], in both species temporal patterning is proposed to arise from lateral connections between glomeruli [86].”
Two-photon calcium imaging reveals an odor-evoked map of activity in the fly brain.
