Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

Advanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Evaluating Aftereffects of Short-Duration Transcranial Random Noise Stimulation on Cortical Excitability

Neural Plasticity, 2011
A 10-minute application of highfrequency (100–640 Hz) transcranial random noise stimulation (tRNS) over the primary motor cortex (M1) increases baseline levels of cortical excitability, lasting around 1 hr poststimulation Terney et al. (2008).

Eye‐Brain Neuroimmune Axis Enables Long‐Term Survival in Glioblastoma by Modulating Brain Immune Surveillance and Neuronal Excitability

Advanced Science, EarlyView.
The eye–brain neuroimmune axis triggers immune activation and disrupts pathological neuronal connectivity to extend glioblastoma survival. ABSTRACT As an anatomical extension of the central nervous system (CNS), the eye harbors rich neural and immune interfaces with the brain. However, the integrated immunological and neurological nexus between the eye

Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway

Advanced Science, EarlyView.
Astrocytic FABP5 promotes mitochondrial stress, cGAS‐STING pathway activation, pyroptosis, and neuroinflammation in epilepsy, contributing to seizure pathology. Genetic targeting of FABP5 or pharmacological inhibition of STING alleviates epileptic phenotypes, highlighting a potential therapeutic strategy for epilepsy.

Reduced intracortical inhibition and enhanced intracortical facilitation in patients with functional tremor

BMJ Neurology Open
Background The pathophysiological mechanism underlying functional tremor (FT) has not been elucidated. Transcranial magnetic stimulation (TMS) is a non-invasive tool to explore cortical excitability in various neurological and neuropsychiatric disorders.

Label‐Free Myelin Fingerprinting: An Adult Human Post‐Mortem Brain Slice Platform via Coherent Anti‐Stokes Raman Spectroscopy

Advanced Science, EarlyView.
A serum‐free, air–liquid interface organotypic slice culture model preserves human post‐mortem corpus callosum tissue, successfully recovering from slicing trauma to reflect the donor's underlying disease state. Pairing label‐free Coherent anti‐Stokes Raman scattering (CARS) microscopy with k‐means clustering enables objective, high‐resolution ...

Cortical excitability dynamics during fear processing [PDF]

, 2019
Background Little is known about the modulation of cortical excitability in the prefrontal cortex during fear processing in humans. Here, we aimed to transiently modulate and test the cortical excitability during fear processing using transcranial ...

Linking cortical network synchrony and excitability [PDF]

Communicative & Integrative Biology, 2016
Theoretical approaches based on dynamical systems theory can provide useful frameworks to guide experiments and analysis techniques when investigating cortical network activity. The notion of phase transitions between qualitatively different kinds of network dynamics has been such a framework inspiring novel approaches to neurophysiological data ...
