Multifractal distribution of spike intervals for two neurons with unreliable synapses [PDF]

arXiv, 2006
Two neurons coupled by unreliable synapses are modeled by leaky integrate-and-fire neurons and stochastic on-off synapses. The dynamics is mapped to an iterated function system. Numerical calculations yield a multifractal distribution of interspike intervals.

Electrical synapses and their functional interactions with chemical synapses [PDF]

Nature Reviews Neuroscience, 2014
Brain function relies on the ability of neurons to communicate with each other. Interneuronal communication primarily takes place at synapses, where information from one neuron is rapidly conveyed to a second neuron. There are two main modalities of synaptic transmission: chemical and electrical. Far from functioning independently and serving unrelated

P3HT‐Based Electroactive Films for In Vitro Neuronal Cell Interfacing

Advanced Materials Interfaces, EarlyView.
Reducing the mechanical mismatch between bioelectronic devices and tissue is crucial for enhancing the characteristics of biointerfaces that better mimic the biological tissues. This work investigates the physico‐chemical properties of tunable nanostructured surfaces obtained from a blend of P3HT and MWCNT electroactive polymer.

Stability and Function of Hippocampal Mossy Fiber Synapses Depend on Bcl11b/Ctip2

Frontiers in Molecular Neuroscience, 2018
Structural and functional plasticity of synapses are critical neuronal mechanisms underlying learning and memory. While activity-dependent regulation of synaptic strength has been extensively studied, much less is known about the transcriptional control ...

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

Advanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

Gap junctions fine-tune ganglion cell signals to equalize response kinetics within a given electrically coupled array

iScience
Summary: Retinal ganglion cells (RGCs) summate inputs and forward a spike train code to the brain in the form of either maintained spiking (sustained) or a quickly decaying brief spike burst (transient).

Synapses: Glia help synapses form and function [PDF]

Current Biology, 1998
AbstractA sophisticated new cell-culture system has shown that glial cells can promote synaptogenesis and enhance the efficacy of synaptic transmission. These effects are not secondary to increased neuronal survival but probably involve changes in neuronal activity levels and a secreted glial factor.

Biological and Mechanical Limitations for Chronic Fast‐Scan Cyclic Voltammetry Sensor Design

Advanced Materials Technologies, EarlyView.
Real‐time detection of neurochemicals has demonstrated value in the field of neuroscience. However, current methods have limitations for use in the chronic setting, which is often the ideal environment for research. This article discusses these limitations, as well as technologies that have been developed to overcome them, and provides recommendations ...

Distinct subpopulations of ventral pallidal cholinergic projection neurons encode valence of olfactory stimuli

Cell Reports
Summary: To better understand the function of cholinergic projection neurons in the ventral pallidum (VP), we examined behavioral responses to appetitive (APP) and aversive (AV) odors that elicited approach or avoidance, respectively.

Integrated Ovonic Threshold Switching Selector and Resistive Switching Memory 1S1R in Electrodeposited ZnTe Thin Films

Advanced Materials Technologies, EarlyView.
This study showcases the first‐ever demonstration of ovonic threshold switching (OTS) and resistive switching (RS) in ZnTe thin films fabricated via a fast, cost‐effective electrodeposition method. By controlling the deposition potential, ZnTe film is tuned to demonstrate OTS or RS behaviors, enabling the implementation of one‐selector‐one‐resistor ...
