Aging Modulates the Resting Brain after a Memory Task: A Validation Study from Multivariate Models.

Recent work has demonstrated that aging modulates the resting brain. However, the study of these modulations after cognitive practice, resulting from a memory task, has been scarce. This work aims at examining age-related changes in the functional reorganization of the resting brain after cognitive training, namely, neuroplasticity, by means of the most innovative tools for data analysis.

Fractal characterization of retinal microvascular network morphology during diabetic retinopathy progression.

Objective: The study aimed to characterize morphological changes of the retinal microvascular network during the progression of diabetic retinopathy.

Methods: Publicly available retinal images captured by a digital fundus camera from DIARETDB1 and STARE databases were used. The retinal microvessels were segmented using the automatic method, and vascular network morphology was analyzed by fractal parametrization such as box-counting dimension, lacunarity, and multifractals.
