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

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

Structure-aware Visualization Retrieval [PDF]
, 2022 With the wide usage of data visualizations, a huge number of Scalable Vector Graphic (SVG)-based visualizations have been created and shared online. Accordingly, there has been an increasing interest in exploring how to retrieve perceptually similar visualizations from a large corpus, since it can benefit various downstream applications such as ...

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

THE VISUAL SYSTEM OF THE ALLIGATOR [PDF]
The Journal of General Physiology, 1957 The eye tissues and liver of the alligator contain vitamin A1 alone. The retina contains rhodopsin, typical in absorption spectrum (λmax 500 mµ); but synthesized in solution from neo-b retinene and opsin much more rapidly than are the frog, mammalian, or chicken rhodopsins previously examined. In this regard alligator rhodopsin resembles the rhodopsins
