Poor surgeries and insufficient training are the main causes of head plate detachment and instability during imaging and recordings in the Mobile HomeCage.
The videos below show the most common types of craniotomies performed at Neurotar – they are meant to help you develop or improve the crucial surgical skills and avoid common mistakes. Scroll to the end for the spinal cord surgery tutorial.
Cranial window for 2-photon imaging
In our experience, this surgery protocol ensures best window recovery rates 3-4 weeks post-surgery:
Cranial window for electrophysiological recordings
Cranial window preparation for ephys applications involves two surgeries. However, acclimation, handling, and training can start in between the surgeries. Follow this link to a typical experimental outline.
Cranial window for the magnetic head fixation
This video shows the craniotomy performed with the magnetic head plate (model 13), which has a large 11 mm opening.

Head plate implantation for functional ultrasound (fUS) imaging
In this video, we demonstrate the procedure of attaching a head plate (model 14) for functional ultrasound (fUS) imaging in awake mice. Please note that fUS head plate does not fit into the standard clamp, use fUS clamp instead:
Chronic spinal window
This video shows how to prepare a chronic spinal window using Neurotar’s spinal cord surgery set:
