3Brain AG, the world’s first company to have placed sophisticated microchips in direct contact with cells to study them, and SuSoS AG, a high-tech company specialized in functional thin film coatings, have entered a commercialization agreement and areworking together to ensure that the 3Brain’s pioneering high-resolution microelectrode arrays (HD-MEA) and CorePlate™ technologies can be adopted quickly by as many users as possible thanks to the advantages brought by SuSoS’ AziGrip4™ CELL+ surface functionalization.

The ISSCR 2021 Annual meeting begins next week on the 21st of June!
We're excited to be sharing more information with you about the HyperCAM Alpha at our booth for all those interested in 3Brain's new CorePlate™ technology for stem cells, ipsc, disease modeling, drug discovery, research, and more!

Reach out to any of us during the event, we are looking forward to sharing with you about the HyperCAM Alpha and our CorePlate™ Technology!

The success of your experiments relies highly on the generation of a robust, efficient and stable model. In this beautiful study from Cutarelli A. et al. (Università di Trento), the authors, faced with the limitations of current protocols for differentiating motor neurons from hiPSCs, have developed a new model optimized to convert hiPSCs into large quantities of functional MNs and their progenitors. Their results obtained with a 3Brain BioCAM system to assess neuronal network functionality are described in this paper.

A big step towards improved cardiotoxicity assessment was made by combining laser-induced cell poration and 3Brain's CMOS HD-MEAs. In this study from Iachetta et al (Istituto Italiano di Tecnologia) the authors describe an effective and reliable method for recording intracellular signals from thousands of cardiac cells simultaneously, compatible with high throughput screenings. This technique, taking advantage of 3Brain high-resolution MEAs properties, improves the reliability and reduces the costs of cardiotoxicity assessments, also by drastically reducing the number of independent experiments required.

Today we'd like to announce our official collaboration with a:head bio AG on the development of 3Brain’s next generation microelectrode array (MEA): the CorePlate ™ technology.
With this collaboration we intend to improve the technology to allow for extraction of highly resolved electric signals from 3D biology in an automated, high-throughput work flow.

In this exciting paper from Norimoto et al., researchers from the Gilles Laurent lab at Max Planck Institute for Brain Research, Frankfurt am Main deciphered the function of a not so well known brain structure, the claustrum, showing how it is involved in the control of brain activity during sleep cycles. Our HD-MEAs helped measure the in vitro propagation velocity of the sharp-wave ripples (SWRs) generated in the claustrum of a reptile (the Australian bearded dragon Pogona vitticeps) during sleep.

New paper released! Beautiful work from Diana Ixmatlahua et al (Rafael Gutiérrez team, Center for Research and Advanced Studies of the National Polytechnic Institute, (Centro de Investigación y de Estudios Avanzados del IPN) Mexico). With the simultaneous recording of thousands of cells on a 3Brain HD-MEA, they discovered that the well-known glutamatergic mossy fiber synapse of the hippocampus was hiding silent but ready-to-use, pH-sensitive, electrical synapses.

We would like to provide an update on 3Brain AG, especially after the press conference held by the Federal Council of Switzerland last Friday.

Due to the events of COVID-19 in Switzerland. We would like to inform and ensure everyone on 3Brain's flow of operations as we will continue to stick to our commitments to our customers. Events will be ensured as far as we can and we will update all personnel by email for any changes ahead of time to avoid inconveniences on your behalf.

If you do have any inquiries, please feel free to get in contact directly with us at: info@3brain.com

One of our first conferences into 2020!

Showing the true potentials of HD-MEAs as to how we bring CMOS technology together with MEAs. Displaying not only the BioCAM DupleX, but also the upcoming BioCAM MultipleX!

As written by JNeurosci, "Electrical coupling between different types of ganglion cells exists in mammalian retinae, highlighting complexity of cross-talk between distinct CNS neural pathways."

This publication shows that with the right tools, researchers still redefine studies that have been taught for well over 20 years!

We attended the event for BraYn 2019 this year. Meeting many young and innovative neuroscientists of the field this year. We hope we brought forth some inspiration for technological advancements in the Neuroscience field, and hopefully be a contribution to the research, experiments, and successes of the young generations today.

This new publication shows an intriguing approach to infere the intrinsic state of neurons starting from large-scale high-density MEA recordings.Applied to 3Brain data it has been made possible to determine the role of the refractory state in spatiotemporal dynamics of developing neonatal retinal waves.

Neurotoxicity and the accumulation of extracellular amyloid-beta1–42 (Aβ) peptides are associated with the development of Alzheimer’s disease (AD) and correlate with neuronal activity and network dysfunctions, ultimately leading to cellular death. However, research on neurodegenerative diseases is hampered by the paucity of reliable readouts and experimental models to study such functional decline from an early onset and to test rescue strategies within networks at cellular resolution. To overcome this important obstacle, in Amin et al., authors used 3Brain's CMOS-chips with 4096-electrodes to model AD on rat hippocampal cell culture.

In a recent paper published on Cell Reports, Hilgen and colleagues presented a "method for automated spike sorting for recordings with high-density, large-scale multielectrode arrays". Exploiting the dense sampling of single neurons by multiple electrodes, an efficient, low-dimensional representation of detected spikes consisting of estimated spatial spike locations and dominant spike shape features is exploited for fast and reliable clustering into single units. Millions of events can be sorted in minutes, and the method is parallelized and scales better than quadratically with the number of detected spikes. Performance is demonstrated using recordings with a 4,096-channel array and validated using anatomical imaging, optogenetic stimulation, and model-based quality control. Their approach demonstrates that it is feasible to reliably isolate the activity of up to thousands of neurons and that dense, multi-channel probes substantially aid reliable spike sorting.
