🤯 👁️ Did you know the primary visual cortex tracks head movements even in complete darkness?

Guy Bouvier and colleagues managed to decode multiple head movement variables in V1 without light in the room, and discovered two distinct brain sources delivering these signals!

Cortical control of a forelimb prosthesis in mice

Robotic upper-limb prostheses aim to restore the autonomy of paralyzed patients and amputees. So far, advances in this field have relied on monkey pre-clinical and human clinical research. Here, we re...

3/4 As learning progressed, the mice learned to coordinate the prosthesis movements across dimensions, and they managed to consolidate a dominant prosthesis trajectory that led to rewards.

Average dominant movement of the prosthesis leading to a rewarded lick. Left: along dimension 1 of the control space. Right: dimension 2. Light curves: individual movements during one session. Thick curve: average over the session.

2/4 Our prosthesis can perform movements in a 3D space next to the body of the mice, that control it via a chronic invasive brain-machine interface. We show that the mice can drive it in a 2D subspace, while some mice managed to control it also in a 3D space.

Left: 2D control subspace. Each dimension is driven by the modulation of one of the neurons recorded in M1. Right: average learning curve, in terms of licks that provided water to the mouse.

1/4 Today we introduce the first upper limb prosthesis for the mouse model, controlled by a brain-machine interface! We show that mice can control this prosthesis via a brain-machine interface to solve a rewarded task.

Left: the upper-limb prosthesis can collect water from a tank, and bring it close to the mouth. Right: skeleton of the prosthesis with 4 DOF. THis prosthesis relies on Bowden cables.

5/6 During cortical wave generation, the response to the movement was reshaped, and lost its relation to limb amplitude, likely being processed to match the task instead.

Luc Estebanez @lucestebanez.bsky.social · Aug 1

4/6 Importantly, limb movements were likely required to trigger rewardable waves, but were only successful when the cortex was in the specific, suppressed state.

Luc Estebanez @lucestebanez.bsky.social · Aug 1

3/6 We have now gone much further, and show that learning this task triggers a reshaping of the cortical dynamics, including a strong suppression of activity before rewardable wave.

Luc Estebanez @lucestebanez.bsky.social · Aug 1

2/6 One year ago, we showed that mice can learn to guide mesoscale cortical of the somatosensory cortex from a start to a target area to obtain rewards.

1/6 We have a new/updated preprint out, led by Anton Dogadov, demonstrating operant conditioning of large cortical waves over mouse S1 thanks to a mesoscale GCamp6 brain-machine interface!

Global and local nature of cortical slow waves:

In brief, we explored in silico how cortical slow waves are shaped by both external inputs and intrinsic properties of neuronal populations.

Explaining the macroscopic activity of a neuronal population from its microscopic properties poses a great challenge, not just because of the many local agents that play a role, but due to the impact ...

How does the brain integrate artificial body extensions? Using a custom-built finger-extending exoskeleton, we show that wearable augmentations are quickly integrated into body representation, with proprioceptive space adapting to the device’s structure and function.
