In one group of reptiles, &lt;i&gt;Caiman crocodilus,&lt;\/i&gt; previous studies have identified three parts of this neuronal aggregate. The central portion, the rotundal core, which receives visual input from the midbrain and projects to a restricted portion of the telencephalon, contains relay cells only. Previous examinations using Nissl morphology indicated that neurons of the rotundal core were not a homogeneous population of cells. The present investigation utilized another methodology to examine cell populations within the rotundal core, immunoreactivity to the calcium binding proteins, calbindin\/calretinin and parvalbumin. Light microscopic observations revealed the following features. First, calbindin\/calretinin immunoreactive neurons and parvalbumin immunoreactive neurons were present in the rotundal core. Of these two antibodies, immunoreactivity to calbindin\/calretinin was much more robust and calbindin\/calretinin immunoreactive neurons were more numerous than parvalbumin cells. Second, neurons immunoreactive to either calbindin\/calretinin or parvalbumin were not homogeneous but comprised several populations based on perikaryal shape and size and neuronal process morphology. These results are compared with similar data in other amniotes.<\/jats:p>","DOI":"10.1159\/000006599","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T15:42:49Z","timestamp":1050421369000},"page":"277-287","source":"Crossref","is-referenced-by-count":24,"title":["Calcium Binding Protein Immunoreactivity in Nucleus Rotundus in a Reptile, &lt;i&gt;Caiman crocodilus&lt;\/i&gt;"],"prefix":"10.1159","volume":"53","author":[{"given":"Michael B.","family":"Pritz","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdolreza","family":"Siadati","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[1999,8,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/0361-9230(94)90086-8"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3940(91)90397-C"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/0165-0173(94)90003-5"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4522(90)90091-H"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/S0306-4522(97)00581-2"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(86)90912-1"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016\/0006-8993(88)90068-6"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3940(94)90721-8"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/0301-0082(91)90009-P"}],"container-title":["Brain, Behavior and Evolution"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/6599","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/6599","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T04:33:50Z","timestamp":1745469230000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000006599"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1999]]},"references-count":9,"journal-issue":{"issue":"5-6","published-online":{"date-parts":[[1999,6,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000006599","archive":["Portico"],"relation":{},"ISSN":["0006-8977","1421-9743"],"issn-type":[{"value":"0006-8977","type":"print"},{"value":"1421-9743","type":"electronic"}],"subject":[],"published":{"date-parts":[[1999]]}}}
