Optical stimulation was provided by a Spectra X Light engine at 585nm (LumenCore) coupled to a Leica DM LFSA microscope and synchronized with video recording at 100fps using LabView software. No statistical difference in behaviour was observed between virally transduced and control groups at baseline, suggesting that there were no side effects from transgene delivery. If the resolution is 300 DPI, then youre good to go. Natl Acad. 22, 14241437 (2019). (2023)Cite this article. These mice exhibited increased apprehension, as revealed both by an overall decreased lever-pressing rate and by an increased time to the next subsequent lever press after a shock trialconsistent with the heightened levels of anxiety that were observed during the EPM and OFT (Fig. Sci. Other nonspecific interventions to alter cardiac rhythms, such as broadly active pharmacological stimulants or electrical pacemakers14, also introduce insuperable confounds through initial actions beyond the direct pacing of cardiomyocytes, and thus lack the necessary precision. Click on Paint. Enter the desired DPI in the box and click OK. Thats all there is to it! Now that youve created your design, its time to download it on your device. We also observed a substantial diversity in temporal dynamics triggered by pacing in other recorded regions, including acute responses in the somatosensory cortex and delayed responses in the striatum during stimulation offset (Fig. We next determined whether systemic viral gene delivery of ChRmine, despite the lower multiplicity of infection compared with transduction by direct local injection30,32, could allow noninvasive control of heart rhythms in wild-type mice. This setting can be changed from the Change Resolution tab under the Design menu and allows users to select from either a standard or high-resolution option. n=20 cells. Genomics 26, 109115 (2006). 8).
