Experiments were performed on frogs. It was shown that 9 neuron types with narrow- and wide-band sensitive characteristics were present in the tectum. These neurons used different modifications of spatio-temporal codes for transfer information about three features of a moving visual object--its orientation, direction and speed. There are proposed conceptual models of neural networks which perform analysis of the visual object orientation, direction and speed of its movement. These models include conceivable structures composed of narrow- and wide-band neurons which "calculate" the parameters of a visual signal through "synaptic interplay" of excitatory and inhibitory inputs based on their different weights on the "recognitive" ("calculative") neuron membrane.

Obtaining high-quality matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) images and the reproducibility of the technique depend strongly on the sample preparation protocol. The most crucial part is the application of the MALDI matrix, which often relies on expensive spraying or sublimation coaters. In this work, we present a new dual-polarity matrix for MALDI mass spectrometry imaging (MSI): Basic Blue 7 (BB7), which belongs to the group of triarylmethane dyes.

Although significant progress of clinical strategy has been made in gene editing and cell engineering in immunotherapy, it is now apparent that design and modification in terms of complex signaling pathways and motifs on medical synthetic biology are still full of challenges. Innate immunity, the first line of host defense against pathogens, is critical for anti-pathogens immune response as well as regulating durable and protective T cell-mediated anti-tumor responses. Here, we introduce DSCI (Database of Synthetic Biology Components for Innate Immunity, https://dsci.

Plant lipids are a diverse group of biomolecules that play essential roles in plant architecture, physiology, and signaling. To advance our understanding of plant biology and facilitate innovations in plant-based product development, we must have precise methods for the comprehensive analysis of plant lipids. Here, we present a comprehensive overview of current research investigating plant lipids, including their structures, metabolism, and functions.

A 45-year-old healthy African-American man experienced 2 months of right-eye soreness followed by acute onset of right painful vision loss with binocular, oblique diplopia. Visual acuity was count fingers OD and 20/20 OS. He had a partial, right, pupil-involving cranial nerve III palsy with a right relative afferent pupillary defect and optic disc edema with tortuous vessels.

Biological vision systems simultaneously learn to efficiently encode their visual inputs and to control the movements of their eyes based on the visual input they sample. This autonomous joint learning of visual representations and actions has previously been modeled in the Active Efficient Coding (AEC) framework and implemented using traditional frame-based cameras. However, modern event-based cameras are inspired by the retina and offer advantages in terms of acquisition rate, dynamic range, and power consumption.
