In this paper, we proposed another model of the minimalist program based on simplicial Hodge theory by taking the relevant brain neural network into account. We focused on a long directed pathway connecting distant areas in the brain, and took the (abstract) simplex spanning the locations on the terminal area, which the signals going through the pathway can reach. The identity of each signal is represented by the symmetry of the corresponding face, consisting of locations receiving the signal simultaneously. Then, we showed that this model fits the minimalist program. Further, we calculated the spectrum and eigenspaces of the Hodge Laplacian in important cases and found their surprising rationality. According to this rationality, we could draw pictures of syntactic relations based only on the calculation without using linguistic knowledge. In addition, though word order depends on what language is used, and thus has nothing to do with the minimalist program, planar word arrangements are still possible and within the scope of our model.<\/jats:p>","DOI":"10.3390\/sym17020207","type":"journal-article","created":{"date-parts":[[2025,1,29]],"date-time":"2025-01-29T07:45:12Z","timestamp":1738136712000},"page":"207","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Simplex Model of Long Pathways in the Brain Related to the Minimalist Program in Linguistics"],"prefix":"10.3390","volume":"17","author":[{"given":"Atsuhide","family":"Mori","sequence":"first","affiliation":[{"name":"Department of Mathematics, Osaka Dental University, Osaka 573-1121, Japan"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"263","DOI":"10.5565\/rev\/catjl.287","article-title":"Some Puzzling Foundational Issues","volume":"2019","author":"Chomsky","year":"2019","journal-title":"Catalan J.
