Frequency Responses of Rat Retinal Ganglion Cells. [PDF]

open access: yesPLoS ONE, 2016
There are 15-20 different types of retinal ganglion cells (RGC) in the mammalian retina, each encoding different aspects of the visual scene. The mechanism by which post-synaptic signals from the retinal network generate spikes is determined by each cell'

On the quantification of SSVEP frequency responses in human EEG in realistic BCI conditions. [PDF]

open access: yesPLoS One, 2013
This article concerns one of the most important problems of brain-computer interfaces (BCI) based on Steady State Visual Evoked Potentials (SSVEP), that is the selection of the a-priori most suitable frequencies for stimulation. Previous works related to
