recommendations! Published in 2017 at "Neuron"

DOI: 10.1016/j.neuron.2017.03.010

Abstract: The perception of visual motion is critical for animal navigation, and flies are a prominent model system for exploring this neural computation. In Drosophila, the T4 cells of the medulla are directionally selective and necessary… read more here.

DOI: 10.1038/s41593-017-0046-4

Abstract: A neuron that extracts directionally selective motion information from upstream signals lacking this selectivity must compare visual responses from spatially offset inputs. Distinguishing among prevailing algorithmic models for this computation requires measuring fast neuronal activity… read more here.

DOI: 10.1167/jov.25.12.21

Abstract: Motion perception is degraded in older adults. Previous studies suggest that this effect of aging may be due in part to an increase in the bandwidth of directionally selective mechanisms. We tested this idea by… read more here.

DOI: 10.7554/elife.35796

Abstract: The orientation of hair bundles on top of sensory hair cells (HCs) in neuromasts of the lateral line system allows fish to detect direction of water flow. Each neuromast shows hair bundles arranged in two… read more here.
