How do we perceive our environment? What is the influence of sensory stimuli on the peripheral nervous system and what on the brain? Science has an interest in this question for many reasons. In the long term, insights from this research could contribute to a better understanding of diseases such as ADHD and Parkinson’s disease.

Perception and the underlying neuronal activities are usually measured while subjects are sitting or lying, for example while doing magnetic resonance imaging. As a rule, the head is fixed and people are encouraged not to blink. The measurements therefore take place under well-controlled but rather unnatural conditions. Continue reading
