We describe a method for implanting and maintaining glass windows over the exposed spinal cords of adult mice for studying experimental autoimmune encephalomyelitis. These windows provide chronic optical access to the spinal cord for monitoring cell dynamics at the subcellular level in live animals using two-photon microscopy.

We have established a cortical orthotopic glioblastoma model in mice for intravital two-photon microscopy that recapitulates the biophysical constraints normally at play during the growth of the tumor. A chronic glass window replacing the skull above the tumor enables the follow-up of the tumor progression over time by two-photon microscopy.

1Movement to Health Laboratory (EuroMov), University of Montpellier, 2Institut Universitaire de France, 3Department of Cognitive Psychology, University of Finance and Management in Warsaw, 4International Laboratory for Brain, Music, and Sound Research (BRAMS)

Behavioral tasks that allow for the assessment of perceptual and sensorimotor timing abilities in the general population (i.e., non-musicians) are presented. Synchronization of finger tapping to the beat of an auditory stimuli and detecting rhythmic irregularities provides a means of uncovering rhythm disorders.

Here, we present a protocol to assess driving behaviors while following a vehicle in a simulated driving environment. The presented protocol is used to compare the impact of different auditory backgrounds on driving behaviors.

This work describes the development of flexible interdigitated electrodes for implementation in 3D brain tumor models, namely, in vitro culture, in ovo model, and in vivo murine model. The proposed method can be used to evaluate the effects of pulsed electric fields on tumors at different levels of complexity.
