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. [...]

Microfluidics

Microfluidics is one of the most dynamic areas of microtechnology. By taking advantage of the benefits of miniaturization, the field of microfluidics has promoted the construction of miniature and inexpensive devices mostly used for analysis and diagnosis. The size of microfluidic devices is small enough so that in experimentation the costs of reagents is small and the time required to perform analysis is greatly reduced. These advantages have given the field of microfluidics a leading hand in the potential to achieve medical and technological breakthroughs and innovations.

The NITRO lab has focused it's microfluidics studies to neuroscience and it's potential in biological applications. Recently, the phenomena of passive pumping has been studied and along with a commercially available and automated delivery system has been used to create fluidic exchanges and high flow rates inside a single microfluidic device without the need for external actuation mechanisms or complex microscale manufacturing.

The following Automated Microfluidic Delivery System Video is a clear example of the rates at which we are able to create fluidic exchanges using a simple channel geometry and two voltage controlled nozzels.
