Abstract: The present invention relates to a method for treating Parkinson's disease. According to this method, a halorhodopsin protein, a polynucleotide encoding the halorhodopsin protein or a vector containing the polynucleotide above is treated to ventrolateral thalamus (VL) or medial globus pallidus (GPm) neurons of a subject having Parkinson's disease, followed by illumination with green light or a T type Ca2+ channel blocker is treated to VL neurons of a subject having Parkinson's disease to inhibit rebound firing of VL neurons. By inhibiting rebound firing of VL neurons, Parkinson's disease can be treated or prevented.

Abstract: The present invention relates to a method for separating and washing microparticles via a stratified co-flow of non-Newtonian fluid and Newtonian fluid, wherein the Newtonian fluid as well as the non-Newtonian fluid may flow into a transfer channel formed in a fluid chip at a predetermined flow rate ratio matching with an effective diameter of the target particles contained in the non-Newtonian fluid, thereby inducing a change in positions of particle focusing points with respect to the target particles within the stratified co-flow thereof formed in the transfer channel. As a result, it is possible to more easily separate only the target particles among the microparticles contained in the non-Newtonian fluid toward the Newtonian fluid without using an additional device and human power, or transfer the target particles contained in the non-Newtonian fluid toward the Newtonian fluid for washing the same.
