Control infarcted nongrafted rats were housed in the enriched environment. Behavioral outcome was repeatedly tested until the rats were killed 20 weeks after the ligation. Ten days earlier, a mixture of 2% Fluoro-Gold and 10% biotinylated dextran amine was injected into the transplants for retrograde and anterograde tracing of graft-host connections.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Results<\/jats:italic>\n            Grafted and nongrafted rats with enriched housing performed significantly better than grafted rats with standard housing on a rotating pole and a prehensile traction test. Grafted \u201cenriched\u201d rats were moreover significantly better than grafted \u201cstandard\u201d rats and nongrafted enriched rats in a rotation test and a postural and locomotor tail position test. In the latter test, nongrafted enriched rats performed significantly better than grafted standard rats. The lesion-induced atrophy in posterior thalamus with its major sensorimotor cortex relay nuclei was significantly reduced in grafted enriched rats compared with nongrafted enriched rats. Afferent and efferent graft-host connections were identified in both grafted groups. Graft volumes did not differ.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            Neural grafting enhanced functional outcome and reduced thalamic atrophy only when combined with housing in enriched environments.\n          <\/jats:p>","DOI":"10.1161\/01.str.28.6.1225","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:08:03Z","timestamp":1308341283000},"page":"1225-1232","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":89,"title":["Neural Grafting to Experimental Neocortical Infarcts Improves Behavioral Outcome and Reduces Thalamic Atrophy in Rats Housed in Enriched but Not in Standard Environments"],"prefix":"10.1161","volume":"28","author":[{"given":"Bengt","family":"Mattsson","sequence":"first","affiliation":[{"name":"From the Laboratory for Experimental Neurology, Wallenberg Neuroscience Center, Lund University Hospital (Sweden) (B.M., B.B.J.), and Department of Anatomy and Cytology, Institute of Medical Biology, Odense University (Denmark) (J.C.S., J.Z.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens Christian","family":"S\u00f8rensen","sequence":"additional","affiliation":[{"name":"From the Laboratory for Experimental Neurology, Wallenberg Neuroscience Center, Lund University Hospital (Sweden) (B.M., B.B.J.), and Department of Anatomy and Cytology, Institute of Medical Biology, Odense University (Denmark) (J.C.S., J.Z.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens","family":"Zimmer","sequence":"additional","affiliation":[{"name":"From the Laboratory for Experimental Neurology, Wallenberg Neuroscience Center, Lund University Hospital (Sweden) (B.M., B.B.J.), and Department of Anatomy and Cytology, Institute of Medical Biology, Odense University (Denmark) (J.C.S., J.Z.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbro B.","family":"Johansson","sequence":"additional","affiliation":[{"name":"From the Laboratory for Experimental Neurology, Wallenberg Neuroscience Center, Lund University Hospital (Sweden) (B.M., B.B.J.), and Department of Anatomy and Cytology, Institute of Medical Biology, Odense University (Denmark) (J.C.S., J.Z.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.07-10-02991.1987"},{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.07-10-03002.1987"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0014-4886(88)90135-5"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1987.tb23718.x"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1988.69.6.0904"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/0014-4886(92)90159-N"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/ana.410340310"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1006\/exnr.1995.1057"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1006\/exnr.1996.0061"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3940(86)90567-7"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/0304-3940(89)90369-8"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1006\/exnr.1995.1011"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1006\/exnr.1994.1086"},{"key":"e_1_3_2_14_2","first-page":"2219","volume":"11","year":"1983","unstructured":"Nieto-Sampedro M, Manthrope M, Barbrin G, Varon S, Cotman CW.
