morphological ontogenesis of the ferret cerebellum and compare its relative time-course to that of the rat cerebellum. Overall cerebellar size, foliation, and thickness of cortical layers were quantified and Purkinje cell morphology was characterized at 24 timepoints in ferrets from postnatal day (P)1 to P63. The ferret cerebellum was substantially larger than that of the rat and had a much longer developmental period. In ferrets, Purkinje cells were dispersed into a monolayer by P9, the formation of folia declined abruptly around P20, and the external granular layer peaked in thickness around P22 and disappeared by P56. Timepoints of corresponding relative developmental maturity of the quantified architectural features of rat and ferret cerebella were determined and their relationship was analyzed by linear regression. The time-conversion equation derived, describing the relationship between cerebellar morphogenesis in the two species, had a determination coefficient (r2) of 0.95. Conspicuously, the equation predicted with high accuracy the timing of structural changes in individual Purkinje cells in the ferret cerebellum. The conversion equation should be useful for precise quantitative translation of data between studies of ferret and rat cerebellum and for comparisons between development of motor and sensory structures and functions in ferrets. The degree of similarity in the time-courses of cerebellar development in two distantly related mammals makes explicit in quantitative terms how remarkably conserved the cerebellum is in phylogenesis. Therefore, the methodology should be applicable to precise quantitative conversions of cerebellar developmental time-courses also between other species. J. Comp.

Ferrets were monocularly deprived for 2, 7 or >14 d, beginning between postnatal day 19 (P19) and P110. The responses of visual cortical neurons to stimulation of the two eyes were used to gauge the onset, peak, and decline of the critical period. MDs ending before P32 produced little or no loss of response to the deprived eye. MDs of 7 d or more beginning around P42 produced the greatest effects. A rapid decline in cortical susceptibility to MD was observed after the seventh week of life, such that MDs beginning between P50 and P65 were approximately half as effective as those beginning on P42; MDs beginning after P100 did not reduce the response to the deprived eye below that to the nondeprived eye. At all ages, 2 d deprivations were 55-85% as effective as 7 d of MD. Maps of intrinsic optical responses from the deprived eye were weaker and less well tuned for orientation than those from the nondeprived eye, with the weakest maps seen in the hemisphere ipsilateral to the deprived eye. Analysis of the effects of 7 d and longer deprivations revealed a second period of plasticity in cortical responses in which MD induced an effect like that of strabismus. After P70, MD caused a marked loss of binocular responses with little or no overall loss of response to the deprived eye. The critical period measured here is compared to other features of development in ferret and cat.", "publicationTitle": "The Journal of neuroscience : the official journal of the Society for Neuroscience", "publisher": "", "place": "", "date": "August 1999", "volume": "19", "issue": "16", "section": "", "partNumber": "", "partTitle": "", "pages": "6965-78", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "", "citationKey": "", "url": "http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=2413141&tool=pmcentrez&rendertype=abstract", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Aging" }, { "tag": "Aging: physiology" }, { "tag": "Animals" }, { "tag": "Critical Period (Psychology)" }, { "tag": "Dominance, Cerebral" }, { "tag": "Ferrets" }, { "tag": "Functional Laterality" }, { "tag": "Functional Laterality: physiology" }, { "tag": "Neuronal Plasticity" }, { "tag": "Neuronal Plasticity: physiology" }, { "tag": "Ocular Physiological Phenomena" }, { "tag": "Sensory Deprivation" }, { "tag": "Vision, Monocular" }, { "tag": "Visual Cortex: physiology" }, { "tag": "visual cortex" } ], "collections": [], "relations": {}, "dateAdded": "2014-05-14T16:06:28Z", "dateModified": "2014-05-14T16:06:28Z" } }, { "key": "669DABN6", "version": 2, "library": { "type": "group", "id": 264830, "name": "Ferrets-cortical folding", "links": { "alternate": { "href": "https://www.zotero.org/groups/ferrets-cortical_folding", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/264830/items/669DABN6", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/ferrets-cortical_folding/items/669DABN6", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1377399, "username": "r03ert0", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/r03ert0", "type": "text/html" } } }, "creatorSummary": "Fietz et al.", "parsedDate": "2010-06", "numChildren": 1 }, "data": { "key": "669DABN6", "version": 2, "itemType": "journalArticle", "title": "OSVZ progenitors of human and ferret neocortex are epithelial-like and expand by integrin signaling.", "creators": [ { "creatorType": "author", "firstName": "Simone a", "lastName": "Fietz" }, { "creatorType": "author", "firstName": "Iva", "lastName": "Kelava" }, { "creatorType": "author", "firstName": "Johannes", "lastName": "Vogt" }, { "creatorType": "author", "firstName": "Michaela", "lastName": "Wilsch-Bräuninger" }, { "creatorType": "author", "firstName": "Denise", "lastName": "Stenzel" }, { "creatorType": "author", "firstName": "Jennifer L", "lastName": "Fish" }, { "creatorType": "author", "firstName": "Denis", "lastName": "Corbeil" }, { "creatorType": "author", "firstName": "Axel", "lastName": "Riehn" }, { "creatorType": "author", "firstName": "Wolfgang", "lastName": "Distler" }, { "creatorType": "author", "firstName": "Robert", "lastName": "Nitsch" }, { "creatorType": "author", "firstName": "Wieland B", "lastName": "Huttner" } ], "abstractNote": "A major cause of the cerebral cortex expansion that occurred during evolution is the increase in subventricular zone (SVZ) progenitors. We found that progenitors in the outer SVZ (OSVZ) of developing human neocortex retain features of radial glia, in contrast to rodent SVZ progenitors, which have limited proliferation potential. Although delaminating from apical adherens junctions, OSVZ progenitors maintained a basal process contacting the basal lamina, a canonical epithelial property. OSVZ progenitor divisions resulted in asymmetric inheritance of their basal process. Notably, OSVZ progenitors are also found in the ferret, a gyrencephalic nonprimate. Functional disruption of integrins, expressed on the basal process of ferret OSVZ progenitors, markedly decreased the OSVZ progenitor population size, but not that of other, process-lacking SVZ progenitors, in slice cultures of ferret neocortex. Our findings suggest that maintenance of this epithelial property allows integrin-mediated, repeated asymmetric divisions of OSVZ progenitors, providing a basis for neocortical expansion.", "publicationTitle": "Nature neuroscience", "publisher": "", "place": "", "date": "June 2010", "volume": "13", "issue": "6", "section": "", "partNumber": "", "partTitle": "", "pages": "690-9", "series": "", "seriesTitle": "", "seriesText": "", "journalAbbreviation": "", "DOI": "10.1038/nn.2553", "citationKey": "", "url": "http://www.ncbi.nlm.nih.gov/pubmed/20436478", "accessDate": "", "PMID": "", "PMCID": "", "ISSN": "", "archive": "", "archiveLocation": "", "shortTitle": "", "language": "", "libraryCatalog": "", "callNumber": "", "rights": "", "extra": "", "tags": [ { "tag": "Animals" }, { "tag": "Cell Count" }, { "tag": "Cell Division" }, { "tag": "Cell Division: physiology" }, { "tag": "Centrosome" }, { "tag": "Centrosome: physiology" }, { "tag": "Centrosome: ultrastructure" }, { "tag": "Epithelial Cells" }, { "tag": "Epithelial Cells: physiology" }, { "tag": "Ferrets" }, { "tag": "Humans" }, { "tag": "Immunohistochemistry" }, { "tag": "In Situ Hybridization" }, { "tag": "Integrin beta3" }, { "tag": "Integrin beta3: metabolism" }, { "tag": "Integrins" }, { "tag": "Integrins: metabolism" }, { "tag": "Microscopy, Electron" }, { "tag": "Neocortex: embryology" }, { "tag": "Neocortex: physiology" }, { "tag": "Neocortex: ultrastructure" }, { "tag": "Neuroglia" }, { "tag": "Neuroglia: physiology" }, { "tag": "Neuroglia: ultrastructure" }, { "tag": "Paired Box Transcription Factors" }, { "tag": "Paired Box Transcription Factors: metabolism" }, { "tag": "Species Specificity" }, { "tag": "Stem Cell Niche" }, { "tag": "Stem Cell Niche: embryology" }, { "tag": "Stem Cell Niche: physiology" }, { "tag": "Stem Cell Niche: ultrastructure" }, { "tag": "Stem Cells" }, { "tag": "Stem Cells: physiology" }, { "tag": "Stem Cells: ultrastructure" }, { "tag": "neocortex" } ], "collections": [], "relations": {}, "dateAdded": "2014-05-14T16:06:28Z", "dateModified": "2014-05-14T16:06:28Z" } }, { "key": "6BHM6T9I", "version": 2, "library": { "type": "group", "id": 264830, "name": "Ferrets-cortical folding", "links": { "alternate": { "href": "https://www.zotero.org/groups/ferrets-cortical_folding", "type": "text/html" } } }, "links": { "self": { "href": "https://api.zotero.org/groups/264830/items/6BHM6T9I", "type": "application/json" }, "alternate": { "href": "https://www.zotero.org/groups/ferrets-cortical_folding/items/6BHM6T9I", "type": "text/html" } }, "meta": { "createdByUser": { "id": 1377399, "username": "r03ert0", "name": "", "links": { "alternate": { "href": "https://www.zotero.org/r03ert0", "type": "text/html" } } }, "creatorSummary": "Kawasaki et al.", "parsedDate": "2004-11", "numChildren": 1 }, "data": { "key": "6BHM6T9I", "version": 2, "itemType": "journalArticle", "title": "Molecular organization of the ferret visual thalamus.", "creators": [ { "creatorType": "author", "firstName": "Hiroshi", "lastName": "Kawasaki" }, { "creatorType": "author", "firstName": "Justin C", "lastName": "Crowley" }, { "creatorType": "author", "firstName": "Frederick J", "lastName": "Livesey" }, { "creatorType": "author", "firstName": "Lawrence C", "lastName": "Katz" } ], "abstractNote": "The visual system encodes and deciphers information using parallel, anatomically segregated, processing streams. To reveal patterns of gene expression in the visual thalamus correlated with physiological processing streams, we designed a custom ferret cDNA microarray.

Within the LGN, odd homeobox1 differentiated the A layers, which contain X cells and Y cells, from the C layers. One neuron-specific protein, Purkinje cell protein 4 (PCP4), was strongly expressed in Y cells in the ferret LGN and in the magnocellular layers of the primate LGN. In the ferret LGN, PCP4 expression began as early as postnatal day 7 (P7), suggesting that Y cells are already specified by P7.
