This type of brain malformation may be associated with other anomalies including hydrocephalus, myelomeningocele, syringomyelia and spina bifida. There are 3 types of Arnold-Chiari malformation (types I, II and III). The clinical symptoms of all 3 types include torticollis, opisthotonus, headache, vertigo, vocal cord paralysis, apnea, nystagmus, dysphagia and ataxia. The Chiari I malformation is considered to be congenital, although there have been reported cases of an acquired form. The incidence of this malformation has been found to be ∼0.56% via magnetic resonance imaging (MRI) studies. The malformation is characterized by a displacement of the cerebellar tonsils, medulla and the fourth ventricle into the spinal canal. The diagnosis can be difficult because not all patients present the classical symptoms of herniated tonsils. However, this anomaly may be diagnosed with MRI. Here we describe a case study of a 22-year-old female patient in a neurology clinic complaining of both headache and vertigo. We determined via MRI that there was a hernia of the cerebellar tonsillar located inferiorly to the foramen magnum. On the other hand the width of the fourth ventricle and the parenchyma tissue of the cerebellum were normal. This type of malformation may prove to be the cause of headache and vertigo in some people. MRI may therefore be a useful tool to aid in the accurate diagnosis of their symptoms.","PeriodicalId":89607,"journal":{"name":"Neuroembryology and aging","volume":"3 1","pages":"149 - 151"},"PeriodicalIF":0.0,"publicationDate":"2004-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000094671","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64346272","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}

We then review the studies showing that receptive fields of auditory thalamocortical neurons express large dynamics in unanesthetized animals. During the time course of different behavioral training protocols, the frequency tuning curves of thalamocortical neurons can be selectively modified to code for the learned importance of acoustic stimuli. In other circumstances, when the vigilance state shifts from waking to sleep, the functional properties of thalamic and cortical neurons exhibit drastic modifications. Finally, we point out new lines of research. First, investigations describing the responses of neurons to communication signals (e.g. species-specific vocalizations) are important because they reveal how the thalamocortical auditory system processes biologically relevant sounds. Second, we suggest that the spike timing precision can largely increase the amount of information transmitted in the thalamocortical auditory system. This urges for more systematic studies in which the temporal organization of spike trains will be considered at presentation of natural stimuli.","PeriodicalId":89607,"journal":{"name":"Neuroembryology and aging","volume":"3 1","pages":"230 - 238"},"PeriodicalIF":0.0,"publicationDate":"2004-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000096800","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64365929","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}

In the first section, maturation of the peripheral vestibular system and the involvement of transcription factors in the patterning of peripheral vestibular components are highlighted. Cell surface and matrix molecules have also been implicated in fasciculation and guidance of axons in the course of vestibular circuit formation. In rodents, the central vestibular neurons continue to develop after birth until they reach maturity in morphology and function. Sequential maturation of neuronal subpopulations within the developing network of the horizontal and vertical otolith systems is also presented. In another section, the expression pattern of glutamate receptor subunits within the developing vestibular nuclear complex is reviewed in relation to their potential role in regulating postnatal function of the vestibular system. Lastly, postnatal changes in the properties of vestibular nuclear neurons and their capability in coding head movement information appear to prime the development of vestibular-related motor functions.","PeriodicalId":89607,"journal":{"name":"Neuroembryology and aging","volume":"563 1","pages":"162 - 170"},"PeriodicalIF":0.0,"publicationDate":"2004-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000096794","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64365890","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}
