Principles & Laws

Neural Encoding & Decoding

At the heart of BCI development lie the principles of neural encoding—the process by which neurons translate stimuli into electrical signals—and decoding, which involves interpreting these signals to infer underlying cognitive or motor states. Dr. Torres's innovations leverage sophisticated models of neural encoding, accounting for the complex dynamics of neural populations and their variable firing patterns.

Amygdala and Cortical Laws

Her research also emphasizes understanding the laws governing neural plasticity and adaptation—particularly how neural circuits reorganize in response to learning and intervention. These principles underpin adaptive BCIs that can evolve with the user, ensuring robustness and long-term usability.

Neural Signal Propagation & Biophysical Laws

Foundational biophysical laws, such as the Hodgkin-Huxley model of action potential propagation and volume conduction principles, inform the design of electrodes and signal processing pipelines essential for accurate neural signal capture in her devices.

Methods & Experiments

Neural Data Acquisition

Dr. Torres employs a variety of neural sensors—from invasive electrode arrays implanted in cortical or subcortical regions to non-invasive techniques like high-resolution EEG and functional near-infrared spectroscopy (fNIRS). Her team advances minimally invasive neural interfaces that maximize signal fidelity while minimizing patient risk.

Neural Signal Processing & Feature Extraction

Utilizing machine learning and deep learning, her methods involve sophisticated algorithms to filter noise, identify relevant neural features, and decode signals related to specific cognitive or motor tasks. Techniques such as spike sorting, local field potential analysis, and recurrent neural networks are employed to interpret complex neural data streams.
