Brain Signal Processing for Brain-Computer Interfaces (BCIs)


The present study aims to develop models to decode spatio-temporal neuronal ensemble firing activities in anterior lateral motor (ALM) cortical neurons into one of the two licking movements (left vs. right). Using the linear discriminant analysis (LDA) classifier and the neuronal selection scheme, we could decode movement direction from ALM neural activity during the delay period after a tactile cue as well as during the movement period with accuracy of as high as 85.46%.
