abstract = {Neurofeedback is a self-regulation technique that can be applied to learn to voluntarily
control cerebral activity in specific brain regions. In this work, a Transcranial Doppler-based
configurable neurofeedback system is proposed and described. The hardware configuration is
based on the Red Pitaya board, which gives great flexibility and processing power to the system.
The parameter to be trained can be selected between several temporal, spectral, or complexity features
from the cerebral blood flow velocity signal in different vessels. As previous studies have found
alterations in these parameters in chronic pain patients, the system could be applied to help them
to voluntarily control these parameters. Two protocols based on different temporal lengths of the
training periods have been proposed and tested with six healthy subjects that were randomly assigned
to one of the protocols at the beginning of the procedure. For the purposes of the testing, the trained
parameter was the mean cerebral blood flow velocity in the aggregated data from the two anterior
cerebral arteries. Results show that, using the proposed neurofeedback system, the two groups
of healthy volunteers can learn to self-regulate a parameter from their brain activity in a reduced
number of training sessions.},
