We work at the intersection of neuroscience and neurotechnology by developing novel measurement and analysis methods for studying human brain structure and function, as well as applying these methods to address important and challenging research questions in both basic and clinical neuroscience. We extensively employ neuromagnetic measurements of brain activity, which give a temporally detailed picture of activation dynamics.

Our aims are

  • to substantially improve the spatial resolution of neuromagnetic measurements by new instrumentation as well as by physiologically-informed computational modeling
  • to develop novel analytical approaches for neuroimaging data, also for real-time use to support closed-loop experiments where the subject's brain activity affects subsequent stimulation; in particular, we focus on assessing functional connectivity between brain regions and between the brains of interacting subjects
  • to investigate the neural processes supporting cognitive functions such as attentional selection, conscious perception, mental imagery and metacognition

Quantum physics and technology research receives billion-euro funding from the EU — Aalto University involved in three projects

Aalto University research groups will study and develop technology for quantum communication, ultra-sensitive magnetic sensors based on quantum optics, and photon-emitting quantum chips. The Quantum Flagship launched by the European Union will provide funding for ten years and for over 5000 researchers with one billion euros. The flagship will consolidate the best quantum physics research in Europe and transfer quantum technology from the lab to the market.

Major funding for developing a new brain research method at Aalto University

Brain imaging has given us a lot of data concerning, for example, how human brains process sensory information.
