Explanted Retina

Shed a light on the processing pathways of the retina

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.

Advantages of 3Brain technology with explanted retinas are:

  • Entire retinal ganglion cell network mapping at single-cell resolution.

  • Record light-induced retinal network activity by combining our BioCAM platform with light-stimulation devices.

  • Combine with optogenetic stimulation tools for spatiotemporally precise excitation/inhibition of cells

  • Single cell visualization of signal propagation

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.
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.
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.
It is a pleasure to work with the 3Brain team, they are both highly skilled experts and friendly.

Fred Jordan's 3Brain Review
The Muotri lab uses 3Brain high-resolution multi electrode arrays to understand how human neural networks are formed during development, and become altered in several neurological conditions.

Prof. Alysson Muotri's 3Brain Review
We engineer a novel plasticity neuroelectronic platform using CMOS-MEA, nano-microtechnology and computational tools to decipher the molecular and functional plasticity simultaneously in a large-scale circuit/network in health and disease.
I have conducted a wide range of brain slices as well as neuron culture experiments in 3Brain's HD MEA system. Their technology is beyond expectation in terms of sensitivity, durability, and high STN ratio.
3Brain has impressed me with the quality of its products. The BioCAM DupleX has been the perfect platform to aid our drug discovery efforts at Xenon, and the personal one-on-one assistance continues to exceed my expectations.
The HD MEAs allow us to perform accurate cardiotoxicity assessments on hiPS cardiomyocytes by applying a novel laser technology for recording high-quality action potentials from thousands of cardiac cells simultaneously.
