Evolution of brain-computer interface: action potentials, local field potentials and electrocorticograms.
Brain computer interfaces (BCIs) were originally developed to give severely motor impaired patients a method to communicate and interact with their environment. Initially most BCI systems were based on non-invasive electroencephalographic recordings from the surface of the scalp. To increase control speed, accuracy and complexity, researchers began utilizing invasive recording modalities. BCIs ...

15 صفحه اولDecoupling Action Potential Bias from Cortical Local Field Potentials
Neurophysiologists have recently become interested in studying neuronal population activity through local field potential (LFP) recordings during experiments that also record the activity of single neurons. This experimental approach differs from early LFP studies because it uses high impedence electrodes that can also isolate single neuron activity. A possible complication for such studies is ...
متن کاملMultichannel Front - End circuit with Action Potentials / Local Field Potentials separation for wireless neural recording
HE bottleneck of the Systems on Chip (SoC) for simultaneous multichannel wireless neural recording is the RF transmitter. It is due to the disproportion between its throughput limited by the requirements of low power consumption and the amount of data acquired from the multielectrode probes. In order to reduce the amount of data without loss of neurobiological information, a sub-band coding tec...
متن کاملLocal field potentials get funny
The local field potential (LFP) is widely used experimentally to index cortical activity and information processing. Classic studies using recordings of LFPs include the first demonstration of long-term potentiation (Bliss & Lomo, 1973) and descriptions of oscillatory brain states (Buzsaki & Draguhn, 2004), while more recent applications extend as far as control of brain–machine interfaces by i...
