. 2025 Feb;
103(3):797-808.
PMID: 39956772
Background: It is known that eyes-open (EO) and eyes-closed (EC) conditions invoke different organizations of brain functional networks, such as sensorimotor, attention, and salience networks in healthy participants. Functional connectivity...

Neuroradiology
. 2024 Jul;
66(11):1917-1929.
PMID: 39039147
Purpose: Due to the indistinguishable clinical features of corticobasal syndrome (CBS), the antemortem differentiation between corticobasal degeneration (CBD) and its mimics remains challenging. However, the utility of conventional magnetic resonance...
