Short periods of bipolar anodal TDCS induce no instantaneous dose-dependent increase in cerebral blood flow in the targeted human motor cortex

open access: yesScientific Reports, 2022
Anodal transcranial direct current stimulation (aTDCS) of primary motor hand area (M1-HAND) can enhance corticomotor excitability, but it is still unknown which current intensity produces the strongest effect on intrinsic neural firing rates and synaptic

Beyond Antibiotics: Photo/Sonodynamic Approaches for Bacterial Theranostics

open access: yesNano-Micro Letters, 2020
Rapid evolution and propagation of multidrug resistance among bacterial pathogens are outpacing the development of new antibiotics, but antimicrobial photodynamic therapy (aPDT) provides an excellent alternative. This treatment depends on the interaction

Neural magnetic field dependent fMRI toward direct functional connectivity measurements: A phantom study [PDF]

open access: yes, 2020
Recently, the main issue in neuroscience has been the imaging of the functional connectivity in the brain. No modality that can measure functional connectivity directly, however, has been developed yet.

Molecular imaging by optically-detected electron spin resonance of nitrogen-vacancies in nanodiamond [PDF]

open access: yesNano Lett 13 (2013) 1173-1178, 2012
Molecular imaging refers to a class of noninvasive biomedical imaging techniques with the sensitivity and specificity to image biochemical variations in-vivo. An ideal molecular imaging technique visualizes a biochemical target according to a range of criteria, including high spatial and temporal resolution, high contrast relative to non-targeted ...
