Hypnotizability exhibits physiological and behavioral correlates in the ordinary state of consciousness and brain morphological peculiarities. Among them, a reduced Grey Matter volume (GMV) of the insula and cerebellar lobules IV\u2013VI has been observed in high hypnotizable individuals (highs) compared to low hypnotizables (lows). Theoretically, these structures could cooperate with the basal ganglia (BG) in hypnotizability-related sensorimotor and cognitive\u2013emotional differences. Methods: Since no imaging study has focused on the BG as a function of hypnotizability, the present research investigated the morphometric characteristics of the BG in the highs (N = 12) and lows (N = 37) enrolled in a previous study focused on the cerebellum. Results: The results did not show any significant difference in the GMV of the caudate and pallidum. Conclusions: Thus, the hypnotizability-related behavioral and physiological difference, as well as the responsiveness to hypnotic suggestions associated with the insula and cerebellum variations, are not partially accounted for by BG structural differences.<\/jats:p>","DOI":"10.3390\/brainsci16030287","type":"journal-article","created":{"date-parts":[[2026,3,4]],"date-time":"2026-03-04T13:11:36Z","timestamp":1772629896000},"page":"287","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["No Association Between Hypnotizability and Basal Ganglia Morphometry"],"prefix":"10.3390","volume":"16","author":[{"given":"Eleonora","family":"Picerni","sequence":"first","affiliation":[{"name":"IRCCS Santa Lucia Foundation, 00179 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabrizio","family":"Piras","sequence":"additional","affiliation":[{"name":"IRCCS Santa Lucia Foundation, 00179 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Laricchiuta","sequence":"additional","affiliation":[{"name":"Department of Philosophy, Social Sciences & Education, University of Perugia, 06123 Perugia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Debora","family":"Cutuli","sequence":"additional","affiliation":[{"name":"IRCCS Santa Lucia Foundation, 00179 Rome, Italy"},{"name":"Department of Psychology, Sapienza University, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7464-5168","authenticated-orcid":false,"given":"Laura","family":"Petrosini","sequence":"additional","affiliation":[{"name":"IRCCS Santa Lucia Foundation, 00179 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2519-1491","authenticated-orcid":false,"given":"Enrica Laura","family":"Santarcangelo","sequence":"additional","affiliation":[{"name":"Department of Translational Research and New Technologies in Medicine and Surgery, University of Pisa, 56127 Pisa, Italy"},{"name":"Istituto di Fisiologia, Via San Zeno 31, 56127 Pisa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1080\/00207144.2014.961870","article-title":"Advancing research and practice: The revised APA Division 30 definition of hypnosis","volume":"63","author":"Elkins","year":"2015","journal-title":"Int.
