Our probes facilitated injections of viral vectors carrying opsin genes while providing collocated neural recording and optical stimulation.
As compared with the film recording and optical reconstruction procedures used for holographic interferometry, the interferometric fringes of AF-ESPI are produced instantly by a video recording system.
Electrical recording and optical imaging of dendrites is difficult, but photoswitches provide an easy way to explore the occurrence and functional consequences of dendritic excitability in all sorts of neurons, including many that were previously inaccessible to electrophysiological manipulation.
The frozen brain slices were used for verification of the recording and optical stimulating sites by observing the different optrode traces inside the slices under a microscope.
Some familiar commercial products are optoelectronic copying machines, laser printers, compact disc players, optical recording media, and optical disc mass-storage systems of exceedingly high bit density.
As far as the applications are concerned, the fabrication of semiconductor nano-dots on GaAs surface is of immense importance in the field of optoelectronics, photonics, recording media, and optical applications.
The ability to simultaneously record electrical and optical characteristics is greatly beneficial for monitoring the integrity of in vitro models of cells.
As methods to record and analyze optical imaging signals become more precise, such biases can have an increasingly pernicious impact on the accuracy of findings, especially in the comparison of cytoarchitechtonic areas, in area-of-activation measurements, and in plasticity or developmental experiments.
To assess the value of the multimodal imaging, we recorded and superimposed optical tomography and SPIM volumes of a Tg neurog1 GFP)× Tg kdrl:rasCherry) embryo expressing green fluorescent protein (GFP) in neuronal cells and mCherry in endothelial cells.
Previous single-unit recording and intrinsic optical imaging studies in macaques have revealed that color-selective neurons are modularly organized in early visual areas (Xiao et al. 2007; Wang et al. 2007; Tanigawa et al. 2010), forming color-specific domains (color maps), where color preference changes gradually across cortical surface, at a spatial scale of tens of microns to ∼0.5 mm.
