However, such modification has not yet been reported in the middle temporal (MT) cortex. A recent study showed that the dimensionality of the spiking activity of MT neurons increases after deployment of spatial working memory. This study is devoted to analyzing the ability of nonlinear and classical features to capture the content of the working memory from the spiking activity of MT neurons. The results suggest that only the Higuchi fractal dimension can be considered as a unique indicator of working memory while the Margaos-Sun fractal dimension, Shannon entropy, corrected conditional entropy, and skewness are perhaps indicators of other cognitive factors such as vigilance, awareness, and arousal as well as working memory.&lt;\/p&gt;&lt;\/abstract&gt;<\/jats:p>","DOI":"10.3934\/mbe.2023176","type":"journal-article","created":{"date-parts":[[2022,12,10]],"date-time":"2022-12-10T05:44:12Z","timestamp":1670651052000},"page":"3749-3767","source":"Crossref","is-referenced-by-count":7,"title":["Higuchi fractal dimension is a unique indicator of working memory content represented in spiking activity of visual neurons in extrastriate cortex"],"prefix":"10.3934","volume":"20","author":[{"given":"Gayathri","family":"Vivekanandhan","sequence":"first","affiliation":[{"name":"Centre for Artificial Intelligence, Chennai Institute of Technology, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahtab","family":"Mehrabbeik","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Amirkabir University of Technology (Tehran Polytechnic), Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karthikeyan","family":"Rajagopal","sequence":"additional","affiliation":[{"name":"Centre for Nonlinear Systems, Chennai Institute of Technology, India"},{"name":"Department of Electronics and Communications Engineering and University Centre of Research &amp; Development, Chandigarh University, Mohali 140413, Punjab"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sajad","family":"Jafari","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Amirkabir University of Technology (Tehran Polytechnic), Iran"},{"name":"Health Technology Research Institute, Amirkabir University of Technology (Tehran Polytechnic), Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen G.","family":"Lomber","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Medicine, McGill University, Montreal H3G 1Y6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yaser","family":"Merrikhi","sequence":"additional","affiliation":[{"name":"Department of Physiology, Faculty of Medicine, McGill University, Montreal H3G 1Y6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2321","reference":[{"key":"key-10.3934\/mbe.2023176-1","doi-asserted-by":"publisher","unstructured":"E.
