Nonverbal Oral Apraxia in Patients with Neurodegenerative Diseases: Clinical-Pathological and Neuroimaging Correlations Research Background Nonverbal Oral Apraxia (NVOA) is a condition characterized by the inability to plan, sequence, and execute voluntary oral-facial movements without muscle weakness. NVOA was first identified in stroke patients, ...

Evoked Component Analysis (ECA): Decomposing Functional Ultrasound Signals Based on GLM Regularization Background The analysis of functional neuroimaging data aims to uncover spatial and temporal patterns of brain activity. Existing data analysis methods mainly fall into two categories: fully data-driven analysis methods and methods that rely on pr...
