Brain implant between neural systems and computer chips. This work is part of a wider research field called brain-computer interfaces. (Brain-computer interface research also includes technology such as EEG arrays that allow interface between mind and machine but do not require direct implantation of a device.) Neural implants such as deep brain stimulation and Vagus nerve stimulation are increasingly becoming routine for patients with Parkinson's disease and clinical depression respectively. Brain implants electrically stimulate, block or record (or both record and stimulate simultaneously) signals from single neurons or groups of neurons (biological neural networks) in the brain. The blocking technique is called
General Data Format for Biomedical Signals BioSig library provides implementations for reading and writing of GDF in GNU Octave/MATLAB and C/C++. A lightweight C++ library called libGDF is also available and implements version 2 of the GDF format. General Data Format for Biomedical Signals The General Data Format for Biomedical Signals is a scientific and medical data file format. The aim of GDF is to combine and integrate the best features of all biosignal file formats into a single file format. The original GDF specification was introduced in 2005 as a new data format to overcome some of the limitations of the European Data Format for
