doi: 10.3389/fnins.2021.613801

Figure Lengend Snippet: Schematic illustration of the experimental setup. (A) Structure and connections of the custom-built apparatus. (B) Assembly of components. Power supplies, lateral camera and control units are shown on the left, interfaces and recording amplifier in the middle part and stimulation devices and computer for data storage on the right. The bottom camera and displaying laptop for positioning the stimulator underneath the mouse paw are shown separately below the other components.

(B) Schematic drawing of the grid plate which can be embedded into the upper platform. (C) Design of the holder for laser/tactile stimulators which fits into the hole in the lower layer of the scaffold. (D) Photo of the custom-made control unit. (E) Photos of the custom made tactile stimulator and its blunt needle. (F) Delay time between trigger and mechanical response to tactile stimulator. The interval decreases as the stimulation strength increases and stabilizes for stimulation voltages from ∼27 V. Mean with SEM.

Figure Lengend Snippet: Electronic design of the tactile stimulator. The 27 V signal is reduced to 5 V to power the NE555 chip which is responsible for the duration of the pulse sent to the actuator. U5 regulates the output voltage to 24 V when the input voltage is equal to, or more than 27 V: Using an input voltage of less than 27 V reduces the force applied to the actuator and increases the actuation time.

Figure Lengend Snippet: Experimental procedures. (A) Upper left: Sites of electrode implantation (scheme showing insertion points for all electrodes used in all mice). Upper right panes and time arrow: time course of experiments. One week following electrode implantation several habituation recordings were done before recording responses to laser/tactile stimulations. (B) Schematic illustration of the stimulation laser with initial diameter of 4 mm and about 50 μm at the focal plane (at 30 mm distance between the stimulator and the grid plate). The length of each grid field is 3.5 ms, which is much larger than the focal diameter of the laser beam. This ensures for reliable targeting of the stimulus after positioning the pilot laser manually through the middle of one of the grid holes. (C) Targeting of right hind paw by laser light (view from bottom camera). (D) Targeting of right hind paw by tactile stimulator. (E) View of the lateral camera showing a mouse in resting state. (F) View of the lateral camera showing the moment of paw withdrawal following laser stimulation.
