Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics
Advanced Materials, EarlyView.Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Common Blood Flow Changes across Visual Tasks: II. Decreases in Cerebral Cortex
Journal of Cognitive Neuroscience, 1997 Nine previous positron emission tomography (PET) studies of human visual information processing were reanalyzed to determine the consistency across experiments of blood flow decreases during active tasks relative to passive viewing of the same stimulus ...

Advanced Materials Interfaces, EarlyView.An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.

The impact of gamma-radiation on the cerebral- and cerebellar- cortex of male rats’ brain
Brain Research Bulletin, 2022 This study aims to investigate the impact of gamma-radiation on the cerebral- and cerebellar-cortex of rat’s brain. Animals were whole-body exposed to 3 Gy, every 3 days, up to 9 Gy, and sacrificed 1 h, 1, 3, 7 & 10 days post the last radiation-dose.

Connectivity-Driven Parcellation Methods for the Human Cerebral Cortex [PDF]
arXiv, 2018 In this thesis, we present robust and fully-automated methods for the subdivision of the entire human cerebral cortex based on connectivity information. Our contributions are four-fold: First, we propose a clustering approach to delineate a cortical parcellation that provides a reliable abstraction of the brain's functional organisation.

Thinning of the cerebral cortex in aging.
Cerebral Cortex, 2004 The thickness of the cerebral cortex was measured in 106 non-demented participants ranging in age from 18 to 93 years. For each participant, multiple acquisitions of structural T1-weighted magnetic resonance imaging (MRI) scans were averaged to yield ...

McGill Journal of Medicine, 2020 Significant structural trimming of neuronal structures in the cerebral cortex has long been considered as a primary cause of various age-related cortical dysfunctions. While recent findings provided additional data to support this notion, current understanding of cortical neuronal functions in aging also revealed the ...

Structure and function of the cerebral cortex [PDF]
Current Biology, 2007 The complexities of cortical circuitry are nothing short of fiendish, and the problem of integrating genetic, morphological and physiological details from diverse cortical areas and across diverse species is a worthy challenge to the burgeoning science of neuroinformatics.

Advanced Optical Materials, Volume 13, Issue 15, May 27, 2025.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 ...
