Microelectrode Brain-machine Interface
INTRODUCTION Spinal cord injury (SCI) is a debilitating condition that affects over 250,000 people in the United States [1]. It results in paraplegia (paralysis of the lower limbs) or in tetraplegia (paralysis of the body below the neck) depending on where along the spinal column is affected [2]. It can result from either a physical injury to the head or spine or can be caused by a degenerative...
متن کاملToward an autonomous brain machine interface: integrating sensorimotor reward modulation and reinforcement learning.
For decades, neurophysiologists have worked on elucidating the function of the cortical sensorimotor control system from the standpoint of kinematics or dynamics. Recently, computational neuroscientists have developed models that can emulate changes seen in the primary motor cortex during learning. However, these simulations rely on the existence of a reward-like signal in the primary sensorimo...
متن کاملBrain Computer Interface using Machine Learning
This paper presents the design and development of a complete hardware and software solution for a brain computer interface (BCI). It consists of a non-intrusive multiple channel data acquisition device which captures the electrical brain wave signals and passes the data to a computer. The computer then uses signal processing and machine learning algorithms to identify patterns in the signals re...
متن کاملBrain-machine interface for eye movements.
A number of studies in tetraplegic humans and healthy nonhuman primates (NHPs) have shown that neuronal activity from reach-related cortical areas can be used to predict reach intentions using brain-machine interfaces (BMIs) and therefore assist tetraplegic patients by controlling external devices (e.g., robotic limbs and computer cursors). However, to our knowledge, there have been no studies ...
متن کاملCoadaptive Brain-Machine Interface via Reinforcement Learning
This paper introduces and demonstrates a novel brain-machine interface (BMI) architecture based on the concepts of reinforcement learning (RL), coadaptation, and shaping. RL allows the BMI control algorithm to learn to complete tasks from interactions with the environment, rather than an explicit training signal. Coadaption enables continuous, synergistic adaptation between the BMI control algo...
