Retinal bipolar cells (BCs) transmit visual signals in parallel channels from the outer to inner retina, where they provide glutamatergic inputs specific networks of amacrine and ganglion cells. Intricate network computation at BC axon terminals has been proposed as a mechanism for complex computation, such direction selectivity, but direct knowledge receptive field property synaptic connectivity various types is required order understand role axonal by BCs. The present study tested...
Retinal waves are correlated bursts of spontaneous activity whose spatiotemporal patterns critical for early activity-dependent circuit elaboration and refinement in the mammalian visual system. Three separate developmental wave epochs or stages have been described, but mechanism(s) pattern generation each their distinct roles development remain incompletely understood. We used neuroanatomical, vitro vivo electrophysiological, optical imaging techniques genetically manipulated mice to...
Spontaneous activity during early development is necessary for the formation of precise neural connections, but it remains uncertain whether plays an instructive or permissive role in brain wiring. In visual system, retinal ganglion cell (RGC) projections to form two prominent sensory maps, one reflecting eye origin and other retinotopic location. Recent studies provide compelling evidence supporting spontaneous eye-specific projections, a similarly retinotopy more equivocal. Here, we report...
Significance Retinal vGluT3 amacrine cells (GACs) release glutamate and glycine to enhance suppress contrast/motion sensitivity, respectively. GACs' relatively compact size diffuse ramification pattern suggest global dendritic processing of visual signals across ON OFF sublayers the inner plexiform layer. Surprisingly, we find that signal spread in GAC dendrites is limited both vertical lateral dimensions. Vertical restriction preserves fundamental ON-OFF segregation scheme, while enables...

Wireless sensor networks are self-organized and data-centric. Security is a critical issue in many applications. In order to protect the security of data, we propose novel secure transmission strategy based on information hiding (IH). this design, acquire sensitive securely so as make use advantage IH technique without encryption. Our approach deal with weakness limitation node resources threats, it suitable for stream data nodes. The simulation experiments also demonstrate that effective...
Optogenetic manipulation with single-cell resolution can be achieved by two-photon excitation. However, this frequently requires relatively high laser powers. Here, we developed a novel strategy that improve the efficiency of current stimulation technologies positioning fluorescent proteins or small molecules cross-sections in vicinity opsins. This generates highly localized source endogenous single-photon illumination tailored to match optimal opsin absorbance. Through neuronal and vascular...

Efficient video transcoding has become a critical technology in content delivery network (CDN) service for social networked application. In this paper, we propose data-driven parallel solution CDN. The key to the is compute ranking of popular videos through web log analysis and then transcode by mapreduce. Experimental results show that our can significantly improve efficiency transcoding.

M1 intrinsically photosensitive retinal ganglion cells (ipRGCs) are known to encode absolute light intensity (irradiance) for non-image-forming visual functions (subconscious vision), such as circadian photoentrainment and the pupillary reflex. It remains unclear how respond relative (contrast) patterned signals. The present study identified a special form of contrast sensitivity (suppressed-by-contrast) in cells, suggesting role signals regulating vision potential ipRGCs encoding...
