Wide-field feedback neurons dynamically tune early visual processing

JC Tuthill, A Nern, GM Rubin, MB Reiser - Neuron, 2014 - cell.com
An important strategy for efficient neural coding is to match the range of cellular responses to
the distribution of relevant input signals. However, the structure and relevance of sensory …

Behavioral state modulates the ON visual motion pathway of Drosophila

JA Strother, ST Wu, EM Rogers… - Proceedings of the …, 2018 - National Acad Sciences
The behavioral state of an animal can dynamically modulate visual processing. In flies, the
behavioral state is known to alter the temporal tuning of neurons that carry visual motion …

A higher order visual neuron tuned to the spatial amplitude spectra of natural scenes

O Dyakova, YJ Lee, KD Longden, VG Kiselev… - Nature …, 2015 - nature.com
Animal sensory systems are optimally adapted to those features typically encountered in
natural surrounds, thus allowing neurons with limited bandwidth to encode challengingly …

Non-canonical receptive field properties and neuromodulation of feature-detecting neurons in flies

C Städele, MF Keleş, JM Mongeau, MA Frye - Current Biology, 2020 - cell.com
Several fundamental aspects of motion vision circuitry are prevalent across flies and mice.
Both taxa segregate ON and OFF signals. For any given spatial pattern, motion detectors in …

A predictive focus of gain modulation encodes target trajectories in insect vision

SD Wiederman, JM Fabian, JR Dunbier, DC O'Carroll - Elife, 2017 - elifesciences.org
When a human catches a ball, they estimate future target location based on the current
trajectory. How animals, small and large, encode such predictive processes at the single …

Neural circuit to integrate opposing motions in the visual field

AS Mauss, K Pankova, A Arenz, A Nern, GM Rubin… - Cell, 2015 - cell.com
When navigating in their environment, animals use visual motion cues as feedback signals
that are elicited by their own motion. Such signals are provided by wide-field neurons …

Visual and motor signatures of locomotion dynamically shape a population code for feature detection in Drosophila

MH Turner, A Krieger, MM Pang, TR Clandinin - Elife, 2022 - elifesciences.org
Natural vision is dynamic: as an animal moves, its visual input changes dramatically. How
can the visual system reliably extract local features from an input dominated by self …

State-dependent decoupling of sensory and motor circuits underlies behavioral flexibility in Drosophila

JM Ache, S Namiki, A Lee, K Branson, GM Card - Nature neuroscience, 2019 - nature.com
An approaching predator and self-motion toward an object can generate similar looming
patterns on the retina, but these situations demand different rapid responses. How central …

Network Adaptation Improves Temporal Representation of Naturalistic Stimuli in Drosophila Eye: II Mechanisms

A Nikolaev, L Zheng, TJ Wardill, CJ O'Kane… - PloS one, 2009 - journals.plos.org
Retinal networks must adapt constantly to best present the ever changing visual world to the
brain. Here we test the hypothesis that adaptation is a result of different mechanisms at …
