Lauri Nummenmaa


Lauri Nummenmaa is a molecular neuroscientist, a Professor in modelling and medical image processing at University of Turku in Finland, where he leads the Human Emotion Systems laboratory at Turku PET Centre and Department of Psychology

He's particularly interested in finding out how the brain processes emotions, with his main specialization being the human emotion science and medical imaging, combining both to better understand the key molecular mechanisms and neural networks behind not only our feelings in different social interactions but also mental illnesses and neurological disorders.

The group he leads is behind the once viral on the internet bodily maps of emotions, groundbreaking in showing clearly how much the bodily processes are dependent on our subjective feelings. They also try to explain many complex phenomenons, such as the popularity of art in many of it’s forms – classical paintings, cinema, but even rock music! 

Furthermore, the group studies functional and molecular neural mechanisms of obesity and weight loss, brain basis of psychopathy the synchronisation of our brains when we’re exposed to same emotions, the topography of human erogenous zones, social communication via interpersonal touch, opioid release after high-intensity interval training, fear of snakes, sociability of music and music-induced hedonia and many more – whith the group even trying to figure out what makes horror movies scary! All that in order to not only improve the overall scientific knowledge and inspire researchers but also to by having the masses understand and remember their findings – improve their health and happiness.
