Chemical AI in the Limelight: The Contribution of Photochromic Materials and Oscillatory Chemical Reactions

Advanced Optical Materials, EarlyView.
Photochromic compounds are versatile ingredients for the development of Chemical AI. When they are embedded in a tight microenvironment, they become Markov blankets. They are also valuable for processing Boolean and Fuzzy logic. They contribute to neuromorphic engineering in wetware based on opto‐chemical signals exchanged with oscillatory chemical ...

Insights on Advances in 3D Bioprinting for Peripheral Nerve Regeneration

Advanced Therapeutics, EarlyView.
Peripheral nerve injury is a common condition due to trauma that significantly impacts the life of the affected individual. This review explores the anatomy, classification, and pathophysiology of peripheral nerve injuries. It also discusses various types of nerve conduits and presents a detailed review of 3D bioprinted nerve conduits used in both in ...

Discrimination of the Healthy and Sick Cardiac Autonomic Nervous System by a New Wavelet Analysis of Heartbeat Intervals [PDF]

Fractals, Vol. 6 No. 3 (1998) 197-203, 1998
We demonstrate that it is possible to distinguish with a complete certainty between healthy subjects and patients with various dysfunctions of the cardiac nervous system by way of multiresolutional wavelet transform of RR intervals. We repeated the study of Thurner et al on different ensemble of subjects.

α‐Synuclein Pathology Spreads in a Midbrain–Hindbrain Assembloid Model

Advanced Science, EarlyView.
A novel midbrain–hindbrain assembloid model demonstrates the spread of α‐synuclein pathology, a hallmark of Parkinson's disease, mimicking Braak's hypothesis. This model reveals how pathology propagates from the hindbrain to the midbrain, inducing synaptic changes and early signs of neuronal vulnerability. It offers an innovative platform for exploring

Muscle‐Derived Small Extracellular Vesicles Mediate Exercise‐Induced Cognitive Protection in Chronic Cerebral Hypoperfusion

Advanced Science, EarlyView.
sEVs have a critical role in orchestrating interorgan crosstalk and mediating exercise‐induced therapeutic effects. Lin et al. demonstrates that sEVs miR‐17/20a‐5p mediates the muscle‐brain crosstalk and emphasizes the central role of mTOR signaling in executing molecular programs that can protect brain health in response to exercise. Abstract Physical

Discrimination between Healthy and Sick Cardiac Autonomic Nervous System by Detrended Heart Rate Variability Analysis [PDF]

arXiv, 1998
Multiresolution Wavelet Transform and Detrended Fluctuation Analysis have been recently proven as excellent methods in the analysis of Heart Rate Variability, and in distinguishing between healthy subjects and patients with various dysfunctions of the cardiac nervous system.

Measures of tonic and phasic activity of the locus coeruleus—norepinephrine system in children with autism spectrum disorder: An event‐related potential and pupillometry study

Autism Research, Volume 15, Issue 12, Page 2250-2264, December 2022., 2022
Abstract A growing body of research suggests that locus coeruleus‐norepinephrine (LC‐NE) system may function differently in individuals with autism spectrum disorder (ASD). Understanding the dynamics of both tonic (resting pupil diameter) and phasic (pupil dilation response [PDR] and event‐related potential [ERP]) indices may provide meaningful ...

Hierarchical learning control for autonomous robots inspired by central nervous system [PDF]

arXiv
Mammals can generate autonomous behaviors in various complex environments through the coordination and interaction of activities at different levels of their central nervous system. In this paper, we propose a novel hierarchical learning control framework by mimicking the hierarchical structure of the central nervous system along with their ...

A Soft Electronics-Free robot [PDF]

arXiv, 2016
Biomimetic entirely soft robots with animal-like behavior and integrated artificial nervous systems will open up totally new perspectives and applications. However, until now all presented studies on soft robots were limited to partly soft designs, since all designs at least needed conventional, stiff, electronics, to sense, process signals and ...
