Methods and systems are disclosed for modeling and decoding neural activities. A brain machine interface (BMI) measures neural activities. A processor receives signals corresponding to the neural activities from the BMI. The processor generates by applying a neural dynamics model signals corresponding to a de-noised state of the neural activities. By applying a BMI decoding model to the de-noised signals, the processor generates a control signal, which is used by a BMI plant model to generate a movement vector. An object is moved according to a predetermined path, in response to the movement vector and the current state of the object. In response to the object's movement, the BMI continuously measures the neural activities. Coefficients of the neural dynamics model and the BMI decoding model are iteratively updated, by executing a learning algorithm, in response to the BMI's continuous measurement.
