Abstract: The present invention relates electrical stimulation of structures having high fiber density, such as white matter tracts of the brain, to effect desired stimulation of associated brain structures. The stimulation of such white matter tracts or other structures can help reduce seizures or otherwise help control seizures by overdriving at least some electrical activity of the associated brain structures.

Abstract: The present invention relates to providing a stimulus to brain structures having high fiber density, such as white matter tracts. The stimulus, which can be electrical, pharmacological and/or genetic, is operative to employ the white matter to affect associated brain structures associated with the white matter to help induce a desired physiological response, such as helping to reduce or control seizures.

Abstract: The device for the performance of sorption processes is in the form of a static mixer and comprises a number of folded double-walled layers which contact one another. The layers are double walled with at least some of the resulting gaps being filled with sorption material. The walls of the layers are permeable by the adsorptives and impermeable by the sorption materials. The device can be used with advantage for chromatography separation processes and permits use of a broad spectrum of sorption materials, increases the working life and improves process reliability.
