One central concept that evolved in the recent years is related to the fact that neurons never function in isolation, they are organized into circuits that process specific kinds of information. Neural circuits are both anatomical and functional entities. The specific architecture of neural circuits in our brain determines who we are and how we make mental representations of the external world. Neurological diseases arise from disrupted neural circuits. MicroBrain Biotech (MBBT) develops cellular neural circuitry-based decision making solutions to de-risk the drug R&D process, by bringing to the market a ground-breaking turnkey solution reproducing a range of one-way connected neural networks and disease-related neuro-anatomical pathways within a cost-effective microsystem which will empower most high contents readout technologies (e.g. high-content imaging, next-generation sequencing, multielectrode arrays, etc.),
