2011 2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society  
We have recorded simultaneous electrocorticographic (ECoG) and hand kinematics in a human subject performing reach-grasp-hold of objects varying in shape and size.  ...  as one ECoG feature from a single electrode (max r for single feature = 0.75) in single trials without prior knowledge of task timing.  ...  The authors would like to thank Steve Hsiao for providing the objects used in the experiment.  ...

Brain-Computer Interface Control of an Anthropomorphic Robotic Arm

Samuel T. Clanton
This BCI system was created as a clinical prototype to exhibit (1) simultaneous decoding of cortical signals for control of the 3-D translation, 3-D rotation, and 1-D finger aperture of a robotic arm and  ...  Two monkeys with chronic microelectrode implants in their motor cortices were able to use the arm to complete an oriented grasping task under brain control.  ...  During the actual reaching trial, progression through the task states was now governed by receipt of grasp events from the autonomous controller.  ...

Inferring intentions from natural eye-movements for biomimetic control of prosthetics and wheelchairs

William Welby Abbott, Aldo Faisal, Engineering And Physical Sciences Research Council
While this is a trivial task in comparison to prosthetic control, unlike many brain machine interface applications it requires continuous closed loop control.  ...  Pong is proposed as a universally accessible benchmark to compare the performance of interfaces.  ...  Thus in order to decode grasp intentions, these grasp associated saccades will need to be differentiated from all the remaining 58% of saccades to extract relevant task related gaze metrics such as fixation  ...

Towards development of a 3-state self-paced brain computer interface system

Ali Bashashati
The majority of BCI research to-date has focused on developing technology for "synchronous" BCIs. These systems allow the user to affect control during specified time periods only.  ...  At first, a comprehensive survey of signal processing algorithms in BCI systems is conducted.  ...  Rossini P M 2004 Human cortical responses during one-bit shortterm memory.  ...

Allostasis and uncertainty: An active inference perspective

This thesis sets out to understand how biological systems deal with uncertainty.  ...  In particular, it investigates the relation between mind and body as understood in philosophy and cognitive science, and the way perception, action, and thought are adaptively co-ordinated in order to  ...  Acknowledgments We thank the anonymous reviewer for their suggested improvements to an earlier version of this chapter.  ...
