Ribbon Synapses Seminar Series 2021

Register for the first Ribbon Synapses Seminar Series 2021 today!
Today's session is focusing on the inner ear (auditory, balance and spatial orientation systems): first enjoy the musical talents of Empire Wild with Ken Kubota, Mitch Lyon and Brandon Ilaw - proudly sponsored by 3Brain AG, followed by a brief introduction from our very own, Sercan Deniz.
Then learn about how we encode sounds and process them in the auditory system with Tobias Moser, from Universitätsmedizin Göttingen, and Katja Bleckmann from Carl von Ossietzky University of Oldenburg. Ruth Anne Eatock from the University of Chicago will then enter into the details of the balance system in the inner ear.

Jointly hosted by Washington University School of Medicine in St. Louis and the Collaborative Research Center of Universitätsmedizin Göttingen.

New publication : "A claustrum in reptiles and its role in slow-wave sleep"

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.

Neuronal Glutamatergic Network Electrically Wired with Silent But Activatable Gap Junctions

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.

Alzheimer's disease on CHIP

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.

Unsupervised Spike Sorting for Large-Scale, High-Density Multi-Electrode Arrays

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.
