Evidence for interhemispheric imbalance in stroke patients as revealed by combining transcranial magnetic stimulation and electroencephalography. [PDF]

Hum Brain Mapp, 2021
We used transcranial magnetic stimulation–electroencephalography (TMS–EEG) to characterize interhemispheric dynamics in stroke patients. We provide a direct evidence of interhemispheric imbalance in stroke patients. TMS–EEG offers a reliable assessment of cerebral state during evolution of stroke.

Multi‐echo quantitative susceptibility mapping: how to combine echoes for accuracy and precision at 3 Tesla

Magnetic Resonance in Medicine, Volume 88, Issue 5, Page 2101-2116, November 2022., 2022
Purpose To compare different multi‐echo combination methods for MRI QSM. Given the current lack of consensus, we aimed to elucidate how to optimally combine multi‐echo gradient‐recalled echo signal phase information, either before or after applying Laplacian‐base methods (LBMs) for phase unwrapping or background field removal.

A phylogenetic survey of the ascomycete genus Arthrorhaphis (Arthrorhaphidaceae, Lecanoromycetes) including new species in Arthrorhaphis citrinella sensu lato

TAXON, Volume 71, Issue 5, Page 936-962, October 2022., 2022
Abstract The genus Arthrorhaphis is a group of ascomycetes comprising lichenised and non‐lichenised taxa from temperate to arctic‐alpine regions in both hemispheres. Nine species and two infraspecific taxa are currently recognised. Their delimitation, inter‐relationships, and phylogenetic placement remain poorly understood.

Patterns of permit requests and issuance for regulated alien and invasive species in South Africa for the period 2015‐2018

African Journal of Ecology, Volume 58, Issue 3, Page 514-528, September 2020., 2020
Abstract Invasive species typically establish in areas outside their natural distribution through accidental introduction and accidental release or escape. Some species are introduced legally for economic and social benefits such as recreational hunting, the pet trade and research through established permitting processes driven by appropriate laws and ...
