Intrinsic Optical Imaging of Whisker Barrel Cortex

Intrinsic optical imaging was performed through the cranial window as previously described (O'Connor et al., 2010 (link)). Mice were lightly anesthetized with isofluorane (0.5% ) and were placed on a heat blanket with their bodies maintained at 37°. Images were acquired using a CCD camera (Retiga-2000RV, Qimaging, Surrey, BC, Canada) through a Leica MZ12.5 microscope (field of view 4.8 x 3.6 mm) with 630 nm LED illumination (Philips LumiLEDs, Amsterdam, Netherlands). The targeted whisker was placed inside a glass pipette connected to a piezoelectric bimorph. The whisker was deflected at 10 Hz for 4 s every 20 s for 10 min. Images were averaged during the 4 s stimulation epoch. A baseline image of the average of the 10 s period proceeding each stimulation epoch was subtracted of this image to generate the intrinsic signal image. Barrels were visible as regions showing decreased 630 nm reflectance. An image of the vasculature was taken with 530 nm LED illumination (Philips LumiLEDs) as a reference for alignment.

Check if the same lab product or an alternative is used in the 5 most similar protocols
A LED (LumiLEDs, Phillips - Netherlands), with a peak wavelength at 660nm, was used as the light source (power output of 100 mW, spot size of 1cm2 and power density of 0.1W/cm2).
Two different energies consisted on 3J and 18J, resulted from 30s and 180s of LED irradiation, were used as sub-lethal and lethal dose of aPDT, respectively [15 (link),22 (link)].
For the in vitro experiments, irradiations were performed from the bottom to the top of the glass test tube and 96 wells plate and for in vivo analysis, larvae were irradiated with a LED (LumiLEDs, Phillips - Netherlands) in a Petri dish plate in a dorsal position.
As a photosensitizer (PS) an aqueous solution of Methylene blue (Sigma Aldrich, Milwaukee, USA) at 100μM were prepared and kept at dark conditions before use.

Wideband Depth Recording and Optogenetic Stimulation

Check if the same lab product or an alternative is used in the 5 most similar protocols
Wideband (0.3–20kHz, sampled at 40kHz) depth recordings were made using the SciWorks recording system (DataWave Technologies), AM-3600 extracellular amplifiers (A-M Systems), and T8G100 headstage amplifiers (TBSI). Photo stimulation was performed with a custom fiber-coupled LED (Philips Lumileds). LED intensity was controlled using a LED driver with analog modulation (Mightex Systems). Analog output pulses were generated within SciWorks and used to control the LED driver.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
