Ex-vivo acute retinal explant

Shed light on retinal activity in vitro. Record responses to light stimuli and generate retinal ganglion cells (RGCs) mosaics.

Models

Whole mount retina explants
Primate and non-primate retina tissues

Advantages

Explanted retinas from different animal models (e.g. murine, salamander, primates, etc.) can be studied up-close on our single-well HD-MEAs or CorePlate™ multiwells. With the largest active microelectrode area on the market (up to 25mm²), they are optimized for recording single cell activity over large tissue samples.

Customer experience

A collection of reviews from our customers

The BioCAM has revolutionized the way we look at population activity in the retina. With its overall large size and spatial resolution, it allows us to study population behaviour at unprecedented spatial and temporal detail.

Retinal Neuroscience See Link to Author’s Publication

The BioCAM offers, for the first time, recordings at a scale that allow validation of models of neuronal population activity. This is a major step that will drive, in turn, the development of theories in neuroscience.

Computational Neuroscience and Neuroinformatics See Link to Author’s Publication

Our laboratory works on brain experimental recordings and modeling on multiple scales, from molecular/cellular to whole brain in animals and humans. The use of BioCAM X integrates perfectly into the workflow as it allows a unique set of measurements on distributed network activities.
