Equine brains from 14 days before expected birth to adulthood were fixed in formaldehyde and embedded in paraffin. After taking the outer parameters of the brains, full series of large-area coronal sections were prepared on a special microtome and stained with Nissl's cresyl violet and Haidenhain's iron-haematoxylin. Microscopic images of sections were digitized and were subjected to computer-aided image analysis. The gross morphology of the brains and the image analysis of histological preparations suggest that in the perinatal period studied there is no substantial increase in brain size and mass, while the amount of Nissl substance and myelin grows rapidly till postnatal day 45. Then a relative decrease of both is observed till adulthood accompanied by a doubling of brain size and mass. It is concluded that during the maturation of the equine brain, decisive changes of the motor system such as up-regulation of protein sysnthesis and full myelination of motor tracts takes place during the critical period of onset of coordinated locomotion.","PeriodicalId":79356,"journal":{"name":"Neurobiology (Budapest, Hungary)","volume":"22 1","pages":"107-35"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85702966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, for such columns to be functionally operative adequate isolation from neighbouring units would be required, otherwise their spatial definition could be compromised. Evidence for \"cable-like\" processes stemming from astroglial cells has been recently presented although their existence has been forgotten for more than a century. These processes tend to form a sort of \"palisade\" or \"brush\" whose spatial distribution appears to correlate with the distribution of apical dendrites within the supragranular cortical layers. Patterned neuronal organization in the striate cortex is associated with a patterned distribution of GFAP-IR processes, both at the cellular and cell-aggregate levels. It can be tentatively proposed that evolutionary pressures resulted, in primates, in the progressive appearance of an increased length of astroglial processes in the supragranular region which may be associated with optimization of cerebral cortex modular (columnar) organization. It is interesting that this cortical region has undergone the larger growth among mammalian species during evolution, and would bear a crucial role in corticocortical interactions.","PeriodicalId":79356,"journal":{"name":"Neurobiology (Budapest, Hungary)","volume":"51 1","pages":"1-16"},"PeriodicalIF":0.0,"publicationDate":"2001-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83513489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
