Johan Lundström's research group
Johan Lundström’s group conducts basic research aimed toward a better understanding of the neural and perceptual basis for multisensory perception and integration of the chemical senses. Several different lines of ongoing research explore how the human brain allows us to perceive, process, and understand sensory information. The group’s research focus on the chemical senses (smell - taste - trigeminal) that, by their very nature, are conveyed almost exclusively as multisensory perceptions. This work involves a wide range of experimental methods, including psychophysical and cognitive tests in healthy individuals, functional brain imaging (fMRI, PET, and EEG/ERP), and structural brain imaging and morphometry. In addition, the lab is actively developing novel ways to deliver olfactory stimuli (olfactometers) and to measure olfactory performance and neural processing.
- Neural processing of perceptual congruency in the chemical senses
- Behavioral and neural impact by the loss of smell in patients with idiopathic/polyp induced anosmia & congenital anosmia
- Neural processing of flavor perception (contact: Dr. Janina Seubert)
- The link between breathing and cognitive performance (contact: Dr. Artin Arshamian)
- Development of olfactory presentation methods
- Social chemosignals impact on perceptual processes
