Massively parallel signal processing using the graphics processing unit for real-time brain–computer interface feature extraction (Tue, 29 Sep 2009 05:43:46 +0000)

PDF Wilson JA, Williams JC Abstract: The clock speeds of modern computer processors have nearly plateaued in the past 5 years. Consequently, neural prosthetic systems that rely on processing large quantities of data in a short period of time face a bottleneck, in that it may not be possible to process all of the data recorded from [...]

Positioning and guidance of neurons on gold surfaces by directed assembly of proteins using Atomic Force Microscopy (Sat, 18 Apr 2009 00:33:13 +0000)

PDF Staii C, Viesselmann C, Ballweg J, Shi L, Liu GY, Williams JC, Dent EW, Coppersmith SN, Eriksson MA. Abstract: We demonstrate that Atomic Force Microscopy nanolithography can be used to control effectively the adhesion, growth and interconnectivity of cortical neurons on Au surfaces. We demonstrate immobilization of neurons at well-defined locations on Au surfaces using two [...]

Two-dimensional movement control using electrocorticographic signals in humans (Mon, 04 Feb 2008 15:49:04 +0000)

PDF G Schalk, K J Miller, N R Anderson, J A Wilson, M D Smyth, J G Ojemann, D W Moran, J R Wolpaw and E C Leuthardt Abstract. We show here that a brain–computer interface (BCI) using electrocorticographic activity (ECoG) and imagined or overt motor tasks enables humans to control a computer cursor in two dimensions. [...]
