PEDOT:PSS—A Key Material for Bioelectronics

Advanced Science, EarlyView.
PEDOT:PSS ‐ Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate ‐ is typically processed from water dispersions to form multifunctional and multidimensional constructs with tunable electronic and ionic conductivity. Throught processing engineering, PEDOT:PSS is intergrated in bioelectronic devices that operate efficiently in physiological conditions

Environmental Stability and Electronic Properties of Individual Flakes of Ti2CTx MXene

Advanced Electronic Materials, EarlyView.
The paper presents a synthesis of large Ti2CTx MXene flakes with sizes reaching 40 µm and examines their environmental stability and electronic behavior. It demonstrates that monolayer flakes degrade rapidly in ambient conditions, leading to semiconducting‐like behavior with low conductivity and mobility. In contrast, multilayer flakes exhibit enhanced

autoMEA: machine learning-based burst detection for multi-electrode array datasets

Frontiers in Neuroscience
Neuronal activity in the highly organized networks of the central nervous system is the vital basis for various functional processes, such as perception, motor control, and cognition. Understanding interneuronal connectivity and how activity is regulated

Poly I:C Activated Microglia Disrupt Perineuronal Nets and Modulate Synaptic Balance in Primary Hippocampal Neurons in vitro

Frontiers in Synaptic Neuroscience, 2021
Perineuronal nets (PNNs) are specialized, reticular structures of the extracellular matrix (ECM) that can be found covering the soma and proximal dendrites of a neuronal subpopulation.

Role of Connexin Channels in the Retinal Light Response of a Diurnal Rodent

Frontiers in Cellular Neuroscience, 2014
Several studies have shown that connexin channels play an important role in retinal neural coding in nocturnal rodents. However, the contribution of these channels to signal processing in the retina of diurnal rodents remains unclear.

New insights into epileptic spasm generation and treatment from the TTX animal model

Epilepsia Open, EarlyView.
Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.

Fast ripple‐delta coupling as an early biomarker for post‐traumatic epileptogenesis in repetitive brain injury

Epilepsia Open, EarlyView.
Abstract Objective Traumatic brain injury (TBI) can induce posttraumatic epilepsy (PTE), but early biomarkers for epileptogenesis are lacking. We aimed to investigate electrographic biomarkers before and during posttraumatic seizure development. Methods We used a repetitive diffuse TBI model in mice with continuous video‐EEG monitoring up to 4½ months ...
