Neurexins play a crucial role in cerebellar granule cell survival by organizing autocrine machinery for neurotrophins

Cell Reports, 2022
Summary: Neurexins (NRXNs) are key presynaptic cell adhesion molecules that regulate synapse formation and function via trans-synaptic interaction with postsynaptic ligands.

Neuromorphic Computing Using Synaptic Plasticity of Supercapacitors

Advanced Science, EarlyView.
A neuromorphic computing pathway based on supercapacitors is presented. MXene Ti₃C₂Tx supercapacitors demonstrate voltage responses under current stimuli, thus exhibiting synaptic plasticity. Energy is stored during response enhancement and released once the response declines.

Cortical synapses of the world's smallest mammal: An FIB/SEM study in the Etruscan shrew

Journal of Comparative Neurology, Volume 531, Issue 3, Page 390-414, February 2023., 2023
The present work provides a quantitative dataset of synapses from the Etruscan shrew (the smallest known terrestrial mammal). We have identified common and differing principles of synaptic organization compared to other mammalian species. Abstract The main aim of the present study was to determine if synapses from the exceptionally small brain of the ...

Implementing Multimodal Hardware Security with 2D α‐In2Se3 Ferroelectric Transistor

Advanced Science, EarlyView.
A multimodal secure transistor‐integrated in‐memory sensing and computing architecture is demonstrated by leveraging its electronic and optoelectronic synaptic behaviors. Key security primitives, such as anticounterfeiting, watermarking, logic locking, and camouflaging, are implemented within a compact single‐transistor structure, providing a scalable ...

Eph and ephrin signaling in the development of the central auditory system

Developmental Dynamics, Volume 252, Issue 1, Page 10-26, January 2023., 2023
Abstract Acoustic communication relies crucially on accurate interpretation of information about the intensity, frequency, timing, and location of diverse sound stimuli in the environment. To meet this demand, neurons along different levels of the auditory system form precisely organized neural circuits.

The Locus Coeruleus‐Periaqueductal Gray GABAergic Projection Regulates Comorbid Pain and Depression

Advanced Science, EarlyView.
LC‐GABA neurons exhibit elevated activity to noxious and aversive stimuli in chronic pain, and their activation alleviates pain‐ and depression‐like behaviors. While LC‐GABA neurons target LC‐NA neurons and GABA and Glu neurons in the vlPAG, they modulate the pain responses of LC‐NA neurons but regulate pain‐ and depression‐like behaviors through their

Structure and evolution of neuronal wiring receptors and ligands

Developmental Dynamics, Volume 252, Issue 1, Page 27-60, January 2023., 2023
Abstract One of the fundamental properties of a neuronal circuit is the map of its connections. The cellular and developmental processes that allow for the growth of axons and dendrites, selection of synaptic targets, and formation of functional synapses use neuronal surface receptors and their interactions with other surface receptors, secreted ...

Changing the responses of cortical neurons from sub- to suprathreshold using single spikes in vivo

eLife, 2013
Action Potential (APs) patterns of sensory cortex neurons encode a variety of stimulus features, but how can a neuron change the feature to which it responds?
