We’ll soon be attending the Swiss 3Rs Day 2026 This annual event brings together the Swiss and international research community to discuss advances in the 3Rs principles: Replacement, Reduction, and Refinement and to promote innovative, responsible approaches in life sciences. At 3Brain, we are proud to support neuroscientists working in 3R‑driven research by enabling high‑content, functional readouts of advanced in vitro neuronal and cardiac models. We're looking forward to engaging with researchers and partners to discuss how CorePlate™ enabled HD‑MEA technology can help reduce animal use while increasing the translational value of complex cellular models. If you’re attending Swiss 3Rs Day 2026, come and say hi Matt and ask him how functional electrophysiology can contribute to more ethical and predictive research. See you there! #Swiss3RsDay #3Rs #3Brain #HDMEA #Electrophysiology #InVitroModels #Organoids #ResponsibleResearch #LifeSciences

One Platform. 96 Wells of Possibility. In our previous post, we explored the signals that you can record from various biological models with the HyperCAM Delta and CorePlate™ 24 & 96W. Now we’re taking a look at a screening example which resulted in dose-dependent functional changes. Using the HyperCAM Delta and CorePlate™ 24W, we accurately characterized a dose-response of primary rat hippocampal neurons under glutamatergic inhibition (NBQX & AP5). What did we see: • High-Quality Data: The high signal-to-noise ratio of all 1,024 electrodes per well resulted in tight error bars and highly reliable data points. • Accurate Network Insights: Beyond simple firing rates, we captured dose-dependent shifts in network activity and connectivity, providing a deeper understanding of the compounds effect. • Efficiency at Scale: Simultaneous recording across all wells and electrodes accelerated screening time. As the concentrations of NBQX & AP5 increased, we observed clear reductions in functional activity, network activity and connectivity, highlighting the strength of HD‑MEA for functional drug screening.

One Platform. 96 Wells of Possibility. In our last post, we explored the range of biological models supported by the HyperCAM Delta and CorePlate™ 24 & 96W. This week, we focus on the signals you can capture from each. From fast neuronal spikes (action potentials) that can be analyzed to reveal single-cell activity and network dynamics of neuronal cultures and brain organoids, to brain organoid field potentials, through to physiologically relevant cardiac waveforms from cardiomyocytes, every signal is captured with precision and clarity. Simultaneous recording across all wells and electrodes allows you to observe complex behaviors, compare conditions side by side, and accelerate decision making. Stay tuned, next, we’ll take a closer look at a screening example of NBQX & AP5 on Rat Primary Hippocampal Cells with CorePlate™ 24W.

The MPS World Summit 2026 is just around the corner! Join us as we meet with scientists and researchers advancing microphysiological systems and human‑relevant models.

Excited to see this work on how we investigate neuroimmune interactions in human brain organoids and assembloids move from preprint to publication in Science Advances! Building on their preprint, this newly published study from Wu et al. from the Yang group at Purdue University show that introducing human microglia into region‑specific brain organoids (cortical, striatal, and midbrain) gives rise to distinct, region‑dependent microglial states that actively shape neuronal development and circuit formation. They further extend this approach by generating microglia‑incorporated midbrain–striatal assembloids, allowing them to model a core circuit implicated in many neuropsychiatric disorders. A major strength of the published work is the functional validation of these assembloids using the HyperCAM Alpha & CorePlate™ 6W which they leveraged in three key experiments. 1. By selectively activating Gq‑DREADDs in midbrain neurons with CNO, the authors demonstrated that increased activity propagates from midbrain to striatum, providing evidence of functional connectivity across the assembloid. 2. They modeled circuit‑level dysfunction in an autism spectrum disorder (ASD) assembloids carrying an SCN2A nonsense mutation, observing significantly elevated neuronal and network activity. 3. By pharmacologically blocking dopamine receptors, they showed a corresponding reduction in striatal activity, functionally confirming the role of projecting midbrain dopaminergic neurons in shaping striatal dynamics. Together with this functional data, this published study displays how microglia act as active regulators of human neuronal circuitry, not merely immune bystanders, and highlights how HD‑MEA electrophysiology can dissect functional interactions within complex 3D brain models.

Translating Technology: Human Brain Slices as a New Screening Platform Testing neuromodulation technologies such as magnetoelectric nanoparticles (MENPs) in relevant models can be a challenge. Although various in vitro and ex vivo platforms such as cell cultures, rodent brain slices, and organoids offer alternatives for screening neural implants before in vivo studies, each still falls short of reproducing the full structural and functional complexity of human brain tissue. New research by Eggert et al., published in the Journal of Neural Engineering, is helping advance this field by establishing organotypic human brain slice cultures as a screening platform for neuromodulation techniques. Using CorePlate™, the team demonstrated spiking and field‑potential activity is present in fresh human brain slices treated with MENPs. Offering a high‑resolution, human‑relevant method which can help develop ideas from engineering concepts to clinical applications, providing an ethically preferable and early‑stage alternative to animal models for evaluating emerging neurotechnologies.
