Billions of neurons that communicate with each other are active in our brains. But what’s actually happening inside our heads?
In the field of neurotechnology, the Ars Electronica Center showcases so-called brain-computer interfaces (BCI). These devices connect the human brain to a computer via electrode caps (EEG) that are non-invasively attached to the scalp. The computer then visualizes how neuronal bioelectrical activities of the brain are measured during different tasks and converted into control signals (for devices, machines, robots, digital writing and muscle stimulation).
In the Update, Erika Mondria (Supervisor Brain Projects / Ars Electronica) und Martin Španka (Contact Person BCI Applications / Ars Electronica Center) offer an overview of bioelectrical signals and the anatomy of our brains and provide fascinating insights into these neuro-technologies.
