Founding developers Ali Nourizonoz and Daniel Huber

Ali Nourizonoz is the developer of BlueBerry hardware, firmware, and software architecture. He is a neuroscientist and engineer at the Sainsbury Wellcome Centre, UCL, specializing in technology development for behavioral neuroscience.

Daniel Huber is an Associate Professor and Head of the Huber Lab at the University of Geneva. He co-developed BlueBerry and leads research combining neuroscience, engineering and behavioral analysis.

Description

BlueBerry is a lightweight, battery-powered wireless optogenetics platform for closed-loop neural stimulation in freely moving animals. By combining wearable electronics, programmable optical stimulation (1 or 2 LEDs), and real-time behavioural feedback, BlueBerry enables precise manipulation of neural circuits without the constraints of tethered systems. This open-source platform, provides researchers with a flexible and scalable solution for behavioural neuroscience experiments.
