چکیده انگلیسی:
In this review, we describe recent experimental observations and model simulations in the research sub-ject of brain-machine interface (BMI). Studies of BMIs have applied decoding models to extract functionalcharacteristics of the recorded neurons, and some of these have more focused on adaptation based onneural operant conditioning. Under a closed loop feedback with the environment through BMIs, neuronalactivities are forced to interact directly with the environment. These studies have shown that the neuronensembles self-reorganized their activity patterns and completed a transition to adaptive state within ashort time scale. Based on these observations, we discuss how the brain could identify the target neu-rons directly interacting with the environment and determine in which direction the activities of thoseneurons should be changed for adaptation. For adaptation over a short time scale, the changes of neuronensemble activities seem to be restricted by the intrinsic correlation structure of the neuronal network(intrinsic manifold). On the other hand, for adaptation over a long time scale, modifications to the synapticconnections enable the neuronal network to generate a novel activation pattern required by BMI (exten-sion of the intrinsic manifold). Understanding of the intrinsic constraints in adaptive changes of neuronalactivities will provide the basic principles of learning mechanisms in the brain and methodological cluesfor better performance in engineering and clinical applications of BMI.
