A neurodevelopmental origin of behavioral individuality in the Drosophila visual system
Science, 2020 Diversity from development When given a line to follow, some fruit flies do so carefully and others weave. Linneweber et al. now show that these behaviors are stable for an individual but diverse in an isogenic population.

Retinal Processing: Insights from Mathematical Modelling
Journal of Imaging, 2022 The retina is the entrance of the visual system. Although based on common biophysical principles, the dynamics of retinal neurons are quite different from their cortical counterparts, raising interesting problems for modellers.

Neuronal diversity and convergence in a visual system developmental atlas
Nature, 2020 Deciphering how neuronal diversity is established and maintained requires a detailed knowledge of neuronal gene expression throughout development. In contrast to mammalian brains 1 , 2 , the large neuronal diversity of the Drosophila optic lobe 3 and its

Development of a rapid point-of-care patient reported outcome measure for cataract surgery in India
Health and Quality of Life Outcomes, 2018 Background For patient undergoing cataract surgery in India, existing patient-reported outcome (PRO) measures are either not culturally relevant, have not been adequately validated, or are too long to be used in a busy clinical setting.

Changes in the perceived size of the body following exposure to distorted self-body images
Royal Society Open Science, 2022 Inaccurate perceptions, such as under- or over-estimation of body size are often found in clinical eating disorder populations but have recently been shown also in healthy people. However, it is not yet clear how body size perception may be affected when

Automated collection of single species of microfossils using a deep learning–micromanipulator system
Progress in Earth and Planetary Science, 2020 For geochemical analysis such as stable isotope ratio, radiocarbon dating and minor element analysis for a single species of microfossils, a large number of specimens, is required. Collecting specimens one by one under a microscope requires enormous time

Near range path navigation using LGMD visual neural networks [PDF]
, 2009 In this paper, we proposed a method for near range path navigation for a mobile robot by using a pair of biologically inspired visual neural network – lobula giant movement detector (LGMD).
