As documented in several publications, active locomotion can strongly modulate cortical activity. I explained earlier how Scanbox uses a quadrature encoder to be able to control, in real time, an external stimulus that depends on the state of locomotion. In this way, we can design experiments in which stimuli are delivered during periods of locomotion or rest. However, if either locomotion…

Simultaneous control of an electrically tunable lens and a pockels cell
We are preparing Scanbox for fast, volumetric scanning, by providing simultaneous control of an electrically tunable lens (to focus on different planes) and a Pockels cell (to control laser power). The Scanbox card has an integrated, 12-bit current source used to control the focus tunable lens. Similarly, an integrated DAC on the Scanbox card controls laser power via a Pockels cell. The…
Read MoreBetter positioning with a wireless 3D mouse
The latest Scanbox release switches its positioning mechanism to rely on the 3dconnection wireless SpaceMouse. A single controller provides a more intuitive, responsive and smoother control of microscope position. It is more intuitive because the panning controls align with the axes of the microscope, and a twist motion of the knob allows you to rotate the…
