Dr Johannes Frasnelli
Professor, Department of Anatomy, UQTR

Comprehension of the Physiology, Psychology, and Pathology of the Chemical Senses

Johannes Frasnelli is a regular professor at the department of anatomy at the Université du Québec à Trois-Rivières (UQTR) since june 2014 and a researcher at the Center for Advanced Research in Sleep Medicine at the Sacré-Cœur de Montréal since october 2013.

He holds the UQTR Research Chair in Chemosensory Neuroanatomy and is member of the CogNAC Research Group (Cognition, Neurosciences, Affect and Behavior) on cognitive neurosciences at UQTR.

His research programs aims at the comprehension of the physiology, psychology, and pathology of the chemical senses, i.e., smell, taste and trigeminal system (which allows for the perception of piquancy, freshness, etc.)

  • The role of trigeminal function in the sensation of nasal obstruction in chronic rhinosinusitis

    The Laryngoscope Volume 126, Issue 5, pages E174–E178, May 2015

    Authors: Joe Saliba MD, Naif Fnais MD, Marcel Tomaszewski MD, Junie S. Carriere BA, Saul Frenkiel MD, Johannes Frasnelli MD andMarc A. Tewfik MD, MSc

    Trigeminal sensation (TS) within the nasal cavity is important for the perception of nasal airflow. The objective of this study is to examine whether impaired TS contributes to the sensation of nasal obstruction in patients with chronic rhinosinusitis (CRS).

  • Brain activations during pain: a neuroimaging meta-analysis of pain patients and healthy controls

    Pain June 2016 - Volume 157 - Issue 6 - p 1279–1285

    Authors: Jensen, Karin B.; Regenbogen, Christina; Ohse, Margarete C.; Frasnelli, Johannes; Freiherr, Jessica; Lundström, Johan N.

    In response to recent publications from pain neuroimaging experiments, there has been a debate about the existence of a primary pain region in the brain. Yet, there are few meta-analyses providing assessments of the minimum cerebral denominators of pain. Here, we used a statistical meta-analysis method, called activation likelihood estimation, to define (1) core brain regions activated by pain per se, irrelevant of pain modality, paradigm, or participants and (2) activation likelihood estimation commonalities and differences between patients with chronic pain and healthy individuals.

  • Grey matter changes of the pain matrix in patients with Burning Mouth Syndrome

    European Journal of Neuroscience Volume 43, Issue 8, pages 997–1005, April 2015

    Authors: Charlotte Sinding, Anne Mari Gransjøen, Gina Schlumberger, Miriam Grushka, Johannes Frasnelli andPreet Bano Singh

    Burning mouth syndrome (BMS) is characterized by a burning sensation in the mouth, usually in the absence of clinical and laboratory findings. Latest findings indicate that BMS could result from neuropathic trigeminal conditions. While many investigations have focused on the periphery, very few have examined possible central dysfunctions. To highlight changes of the central system of subjects with BMS, we analysed the grey matter concentration in 12 subjects using voxel-based morphometry.
