Abstract The size, shape, and nanoscale organization of synaptic spines are predictive of physiological synaptic strength and thus key to connectome-based neural circuit models. In the intact brain, spine size and shape undergo continuous morphological remodeling. While these nanoscale morphodynamics are not …

Improving behavioral performance relies on the ability to associate decisions with their positive and negative outcomes. Although neurons that associate actions with their consequences have been identified across multiple brain regions, the circuit-level mechanisms underlying this integration remain poorly understood. Here, using …

In primates, primary visual cortex (V1) circuits support early visual processing, whereas in the lateral prefrontal cortex (LPFC), they support higher-order computations. Here, we characterized the intrinsic electrophysiological (e)-properties and morphology of excitatory (EXC), fast-spiking inhibitory (FSI), and non-fast-spiking inhibitory (NFSI) neurons …

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 electrode limits frequency coding and speech understanding in daily situations …

Sixty years after the concept of population coding in neuronal networks was introduced, we still lack a comprehensive understanding of its performance limits and the role of neuronal physiology. Here, we use dynamic gain analysis in a general model of population coding …

Detection and tracking of animals is an important first step for automated behavioral studies using videos. Animal tracking is currently done mostly using deep learning frameworks based on keypoints, which show remarkable results in lab settings with fixed cameras, backgrounds, and lighting. …

Perceptual processing may rhythmically alternate. There is a line of evidence from dense sampling psychophysics supporting this claim: In such studies, performance in visual target detection or discrimination is repeatedly tested at various fine-grained time intervals relative to a reference event. This …

Abstract Retinal ganglion cells, the output neurons of the vertebrate retina, often display nonlinear summation of visual signals over their receptive fields. This creates sensitivity to spatial contrast, letting the cells respond to spatially structured visual stimuli even when no net change …

The retina encodes a broad range of stimuli, adapting its computations to features like brightness, contrast, and motion. However, it is unclear whether it also adapts when switching between natural scenes and white noise (WN). To address this, we analyzed the neural …

Abstract Optogenetics is a promising approach for restoring vision after photoreceptor degeneration. Yet, little is known about how responses to natural stimuli in optogenetically treated retinas compare to photoreceptor-driven responses and how any differences might be counteracted by adjusting the stimulation. We …

Cell junction remodeling is central to epithelial morphogenesis and tissue rheology and depends on the interplay between adhesion molecules and the actomyosin cortex. E-cadherin constitutes the molecular basis for epithelial cell adhesion, whereas cortical actomyosin plays a major role in intracellular force …

Among non-human primates, macaques are recognized for thriving in a wide range of novel environments. Previous studies show macaques' affinity for new information. However, little is known about how information-seeking manifests in their spatial navigation pattern in ambiguous foraging terrains, where the …
