Centered Kernel Alignment Enhancing Neural Network Pretraining for MRI-Based Dementia Diagnosis

This article was published by the Signal Processing and Recognition Group (Universidad Nacional de Colombia). The study addresses an automated dementia diagnosis by introducing a novel supervised pretraining approach that takes advantage of the artificial neural network for complex classification tasks. The performed linear embedding allows accounting for features that contribute the most to the […]


Tactile stimulation during sleep alters slow oscillation and spindle densities but not motor skill

A paper was recently published by a group of LabCrono UFPR Brazil. The study features a novel tactile stimulation during sleep. It was shown that this technique did not impact on the offline gains in motor skill, but altered slow oscillations and spindle densities. Alterations in electrophysiology parameters didn’t translate into behavioral changes. Paper available […]
