Bio‐inspired inorganic/organic semiconductor heterostructure synapses with UV–visible–NIR wavelength‐dependent responses for image recognition

InfoMat, EarlyView.
This study presents a SnSe2/DNTT heterostructure photonic synaptic transistor that exhibits wavelength‐dependent photoresponses and synaptic plasticity. Operating with low energy consumption, the device extends spectral sensitivity from ultraviolet (UV) to near‐infrared (NIR) wavelengths, significantly enhancing neuromorphic computing performance.

Calpain-5 Expression in the Retina Localizes to Photoreceptor Synapses

Investigative Opthalmology & Visual Science, 2016
We characterize calpain-5 (CAPN5) expression in retinal and neuronal subcellular compartments.CAPN5 gene variants were classified using the exome variant server, and RNA-sequencing was used to compare expression of CAPN5 mRNA in the mouse and human retina and in retinoblastoma cells.

Opportunities for 2D‐Material‐Based Multifunctional Devices and Systems in Bioinspired Neural Networks

Small, EarlyView.
Bio‐inspired computing offers a route to highly energy‐efficient artificial intelligence. The unique physical properties of two‐dimensional (2D) materials can further enhance such computing approaches. This perspective highlights recent developments in 2D materials‐based neuromorphic devices and discusses future opportunities for integrating such novel

Analysis of RIM Expression and Function at Mouse Photoreceptor Ribbon Synapses [PDF]

The Journal of Neuroscience, 2017
RAB3A-interacting molecule (RIM) proteins are important regulators of transmitter release from active zones. At conventional chemical synapses, RIMs contribute substantially to vesicle priming and docking and their loss reduces the readily releasable pool of synaptic vesicles by up to 75%. The priming function of RIMs is mediated via the formation of a

Synergistic Pyroelectric‐Bolometric Coupling in Tellurene Nanowire for Energy‐Efficient Artificial Vision

Small, EarlyView.
Synergistic pyroelectric–bolometric coupling in Tellurene nanowires enables efficient photothermal conversion and self‐driven synaptic functionality. Edge‐induced polarization and temperature‐dependent resistance cooperatively generate enhanced transient responses and multilevel conductance states.

Rod photoreceptors drive circadian photoentrainment across a wide range of light intensities. [PDF]

, 2010
In mammals, synchronization of the circadian pacemaker in the hypothalamus is achieved through direct input from the eyes conveyed by intrinsically photosensitive retinal ganglion cells (ipRGCs).
