Case report: A 53-year-old woman with cervical dystonia underwent magnetoencephalography pre- and post-botulinum toxin injection and sensory trick, which was described as yawning. Study revealed connectivity between the left frontal and inferior frontal gyrus before yawning, which changed to the visual cortex and right middle frontal gyrus with yawning. Beta frequencies reduced and gamma frequencies increased after yawning. Discussion: The increase in gamma frequency bands may indicate increased GABAergic activity. Increase in connectivity in the right cerebellar region underscores the importance of cerebellum in pathogenesis of dystonia.<\/jats:p>","DOI":"10.3390\/brainsci8040051","type":"journal-article","created":{"date-parts":[[2018,3,22]],"date-time":"2018-03-22T05:14:55Z","timestamp":1521695695000},"page":"51","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Sensory Trick in a Patient with Cervical Dystonia: Insights from Magnetoencephalography"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8807-6672","authenticated-orcid":false,"given":"Abhimanyu","family":"Mahajan","sequence":"first","affiliation":[{"name":"Department of Neurology, Henry Ford Hospital, 2799 West Grand Boulevard, K-11, Detroit, MI 48202, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Zillgitt","sequence":"additional","affiliation":[{"name":"Department of Neurology, Henry Ford Hospital, 2799 West Grand Boulevard, K-11, Detroit, MI 48202, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan","family":"Bowyer","sequence":"additional","affiliation":[{"name":"Department of Neurology, Henry Ford Hospital, 2799 West Grand Boulevard, K-11, Detroit, MI 48202, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christos","family":"Sidiropoulos","sequence":"additional","affiliation":[{"name":"Department of Neurology, Henry Ford Hospital, 2799 West Grand Boulevard, K-11, Detroit, MI 48202, USA"},{"name":"Department of Neurology and Ophthalmology, Michigan State University, East Lansing, MI 48823, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"882","DOI":"10.1136\/jnnp-2013-307316","article-title":"Alleviating manoeuvres (sensory tricks) in cervical dystonia","volume":"85","author":"Patel","year":"2014","journal-title":"J.
