Optogenetic cochlear stimulation evokes midbrain activity with near-physiological temporal fidelity

Authors Koert E, Götz J, Albrecht N, Vavakou A, Wolf BJ, Moser T Journal BioRxiv Citation bioRxiv 2026.05.16.724905 Abstract When hearing fails, stimulation of the auditory nerve by electrical cochlear implants (eCIs) partially restores hearing, with most eCI users achieving open speech understanding. However, the broad current spread from each

Universal approach to wave-optical calculations of point spread functions in microscopy (and beyond)

Authors Gligonov I, Loetgering L, Tenopala-Carmona F, Hsieh CL, Gregor I, Enderlein J Journal BioRxiv Citation bioRxiv 2026.04.28.721333 Abstract Optical microscopy is fundamental to modern life-science research, yet interpreting its results requires precise modelling of point spread functions (PSFs) within complex environments. This manuscript introduces a versatile and efficient approach

Image modifications reduce differences in natural-image encoding by retinal ganglion cells between natural and optogenetic stimulation

Authors Ramakrishna V, Gollisch T Journal BioRxiv Citation bioRxiv 2026.03.06.710066. Abstract Photoreceptor degeneration is among the leading causes of blindness and optogenetics as a potential therapeutic measure has garnered much attention over recent years. In this approach, light-sensitive molecules like Channelrhodopsin-2 (ChR2) are inserted into neurons in the retina to

A transition-prone brain state precedes spontaneous behavioral switching

Authors Wanken P, Edelman BJ, Behera L, Martinez de Paz JM, McCarthy PT, Macé E Journal BioRxiv Citation bioRxiv 2026.03.06.709845. Abstract Animals exhibit behavior in the absence of external stimuli or explicit tasks. Is the initiation of such spontaneous behavior shaped by internal brain states in a predictable manner? If

Mechanism of human tRNA 3′CCA maturation

Authors Kuhle B, Krebs L, Bhatta A, Dennerlein S, Rehling P, Hillen H Journal BioRxiv Citation bioRxiv 2026.03.02.709036. Abstract The non-templated addition of the 3′CCA end is the final universal step of tRNA maturation. In humans, 3′CCA addition on nuclear- (nu-tRNA) and mitochondria-encoded tRNAs (mt-tRNA) is catalyzed by a single
