Genetic Analysis and Cell Manipulation on Microfluidic Moreover, spatially specific capture and selective temperature-mediated release of cells on design-specified areas is presented, which demonstrates the ability to establish cell arrays on pre-defined regions and to collect only specifically selected cell groups for downstream analysis. Hippocampal Place Fields Emerge upon Single-Cell Aug 17, 2012 · The origin of the spatial receptive fields of hippocampal place cells has not been established. A hippocampal CA1 pyramidal cell receives thousands of synaptic inputs, mostly from other spatially tuned neurons; however, how the postsynaptic neurons cellular properties determine the response to these inputs during behavior is unknown. We discovered that, contrary to expectations
Jan 04, 2000 · Individual cells or liposomes were first selected and manipulated either by optical trapping or by adhesion to a micromanipulator-controlled ultramicroelectrode. Spatially selective fusion of the cell-cell or cell-liposome pair was achieved by the application of a highly focused electric field through a pair of 5-micrometer o.d. carbon-fiber ultramicroelectrodes. Measurement of UV absorption of single living cell for Feb 15, 2009 · The selective photo-disruptions of single living cell and sub-organelle (nucleus) were demonstrated using the tightly focused NIR femtosecond laser before the measurement of UV absorption of living cell. The microscopic views of the photo-disruption of single living cell excited by the femtosecond laser irradiation were shown in Fig. 3. Spatial and Chemical Surface Guidance of NK Cell Cytotoxic Studying how different signaling pathways spatially integrate in cells requires selective manipulation and control of different transmembrane ligand-receptor pairs at the same time. This work explores a novel method for precisely arranging two arbitrarily chosen ligands on a micron-scale two-dimensional pattern.
May 21, 2014 · We used the spot scan function to target the laser at a single cell body and assessed our ability to selectively stimulate that cell. We were usually able to stimulate a single targeted cell on untreated polished silicon, while similar stimulation on the porous oxidized silicon and porous carbonized silicon (Figures 5AF ) resulted in a larger region of stimulation. Targeted Activation of Hippocampal Place Cells Drives Hippocampal place cells exhibit spatially selective activity within an environment and have been proposed to form the neural basis of a cognitive map of space that supports these mnemonic functions. However, the direct inuence of place cell activity on spatial navigation behavior has not yet been demonstrated. Using an all-optical combination US7092599B2 - Wavelength manipulation system and The cell regions each can include a plurality of drivable cells and wherein, in use, the cells are preferably driven so as to provide a selective driving structure which projects a corresponding optical signal falling on the cell region substantially into one of a series of output order modes.
