WebOct 21, 2024 · Optogenetic stimulation of the CnF increases locomotor activity in Vglut2-ChR2-EYFP mice lesioned with 6-OHDA. (A) Vglut2-ChR2-EYFP mice were either injected in the striatum with vehicle or 6-OHDA (see Materials and Methods) and implanted ∼500 μm above the right CnF with an optic fiber. After 3 d, the effects of optogenetic stimulation of ... WebMay 25, 2024 · In order to achieve efficient optogenetic excitation using minimal light power and to minimize crosstalk between optogenetic stimulation and jRCaMP1a imaging, we used the high-conductance, blue-light-sensitive opsin CoChR (Klapoetke et al., 2014).To improve the spatial specificity of stimulation, we restricted the presence of CoChR …

WebDec 7, 2024 · The 300 kHz ultrasonic beams pulsed at 40 Hz with 3-ms pulse width were applied transcranially. The stimulation trains of 200-ms ON and 800-ms OFF periods were repeated in stimulation blocks of 10-s ON and 30-s OFF periods (Fig. 1c). The duration of stimulation session was 2 h daily and repeated for 2 weeks.
