Research Areas
Currently, the NEPEB main areas of research are:Objective detection of the evoked response by sensory stimulation:
One of the main interest topic of this research group is the development and
application of statistical methods for analysis of the evoked response by sensory
stimulation. In this experimental paradigm, the focus is to identify central
nervous system response to visual, auditory and somatosensory.
Brain-machine interfaces:
The Biomedical Engineering Laboratory has been studying techniques for pattern detection
in the EEG signals to be used as control commands
for electrical/electronic devices (orthoses, prostheses, wheelchairs).
Motor imagery:
It is well known that the imagination of certain movements results in brain neuronal recruitment
pattern similar to that obtained by the movement execution itself. Thus, several studies have
been conducted on the use of EEG signals during motor imagery in brain-machine interfaces.
Pupillometry:
This project involves the development of mathematical methods to be applied to
pupil diameter time series, which may be an important indicator of neurological
condition such as narcolepsy.
Auditory Stimulator with arbitrary waveform:
The objective of this project is the development of a stimulator capable of generating
stimulation by clicks, sine and sine amplitude modulated, aiming its use in investigation
of hearing loss and auditory threshold determination.
Neurostimulator by electrical current with arbitrary waveform:
This work aims at developping a neuro-stimulator that can generate arbitrary waveform
of electrical current whose wave parameters can be easily programmed via software.
