Advanced Healthcare Materials, Volume 14, Issue 4, February 7, 2025.Area‐selective atomic layer deposition (ASD) offers wide‐ranging potential for the use on active implants. As the active implants consist of heterogeneous materials, this provides an excellent basis for the application of ASD. In this review, processes for the application on active implants and possible application scenarios are highlighted.

Journal of Neurochemistry, Volume 169, Issue 1, January 2025.The study sheds light on how medial forebrain bundle Deep Brain Stimulation (mfb‐DBS) triggers neural activity and dopamine release in free and behaving animals. Over 8 weeks, 130 Hz mfb‐DBS significantly boosted accumbal dopaminergic activity, increasing phasic and tonic responses.

Ecology Letters, Volume 27, Issue 11, November 2024.In this work, we combine process‐based models and neural networks into process‐informed neural networks (PINNs), which incorporate the process knowledge directly into the neural network structure. In a systematic evaluation of spatial and temporal prediction tasks for C‐fluxes in temperate forests, we show the ability of five different types of PINNs ...

Recording Quality Is Systematically Related to Electrode Impedance
Advanced Healthcare Materials, Volume 13, Issue 24, September 25, 2024.Electrode coatings bringing the impedance of small electrodes closer to the impedance of large ones and allow increased spike selectively without sacrificing the SNR and unit‐yield. This study shows that in chronic recordings, signal quality and unit yield are negatively correlated with electrode impedance.

Low rate hippocampal delay period activity encodes behavioral experience
Hippocampus, Volume 34, Issue 8, Page 422-437, August 2024.Abstract Remembering what just happened is a crucial prerequisite to form long‐term memories but also for establishing and maintaining working memory. So far there is no general agreement about cortical mechanisms that support short‐term memory.

Advanced Science, Volume 11, Issue 27, July 17, 2024.Direct current electric fields (dcEFs) naturally occur in wound healing or cancer metastasis. The stimulus to generate dcEFs may release toxic stimulation by‐products. The release can be delayed by increasing the capacitance of the stimulation electrode by coating the surface with conducting polymers.

Flexible Polymer Electrodes for Stable Prosthetic Visual Perception in Mice
Advanced Healthcare Materials, Volume 13, Issue 15, June 13, 2024.Flexible polymer‐based electrodes of minimal size (<15 um2) exhibit exceptional stability, enduring billions of pulses in vitro. In mice, microstimulation of the visual cortex elicits perception at current amplitudes as low as 2 µA and electrodes exhibit sustained functionality up to 55 weeks.

Fabrication and Characterization of PDMS Waveguides for Flexible Optrodes
Advanced Healthcare Materials, Volume 13, Issue 16, June 25, 2024.The demand for optical probes tailored to applications is ever rising for optogenetic research. Specifically, for applications such as the cochlea, transitioning from stiff glass fibers to flexible probes is required, especially for long‐term use. Polydimethylsiloxane with its low Young's modulus can serve as material of choice. Its long‐term usability

Advanced Functional Materials, Volume 34, Issue 11, March 11, 2024.A novel approach presents neural thin film interfaces as resonating systems. Direct measurements prove mechanical–electrical nano‐vibrations of thin film metallization in response to electrical current during stimulation. The correlation between electrochemical reactions and mechanical deformation unveils insights into potential fatigue and failure ...

Technology and the origin of human hemispheric asymmetry [PDF]
This paper proposes that human asymmetrical hemispheric function originated because of the cognitive requirements of tool-making. The human brain can be considered to be a product of two evolutionary episodes.
