“…However, the neuronal regulation cited by authors above could not be evidenced since our study was based only on morphological analysis during the fetal period. In addition to this information, Tapia (1997), Amarante-Mendes & Green (1999) and Ferrari et al (2001) reported that for mammals in general, there is a regulation on the number of neurons in the CNS after birth.…”

This study describes the development of the central nervous system in guinea pigs from 12th day post conception (dpc) until birth. Totally, 41 embryos and fetuses were analyzed macroscopically and by means of light and electron microscopy. The neural tube closure was observed at day 14 and the development of the spinal cord and differentiation of the primitive central nervous system vesicles was on 20th dpc. Histologically, undifferentiated brain tissue was observed as a mass of mesenchymal tissue between 18th and 20th dpc, and at 25th dpc the tissue within the medullary canal had higher density. On day 30 the brain tissue was differentiated on day 30 and the spinal cord filling throughout the spinal canal, period from which it was possible to observe cerebral and cerebellar stratums. At day 45 intumescences were visualized and cerebral hemispheres were divided, with a clear division between white and gray matter in brain and cerebellum. Median sulcus of the dorsal spinal cord and the cauda equina were only evident on day 50. There were no significant structural differences in fetuses of 50 and 60 dpc, and animals at term were all lissencephalic. In conclusion, morphological studies of the nervous system in guinea pig can provide important information for clinical studies in humans, due to its high degree of neurological maturity in relation to its short gestation period, what can provide a good tool for neurological studies.

“…As interligações das células nervosas não ocorrem de maneira fixa, estão em contínua mudança estrutural, principalmente por conta dos estímulos sensoriais, ou seja, o cérebro é plástico (FERRARI et al, 2001). Como elementos que dificultam a plasticidade neuronal estão a especialidade ou programação das células nervosas e a idade do indivíduo.…”

RESUMOEste trabalho explora algumas descobertas das neurociências com implicação com a educação, em especial com a aquisição e o aprendizado da escrita. O Izquierdo (2002Izquierdo ( , 2004, Boujon e Quaireau (2000), discute-se e especulase sobre as seguintes questões: dissimetrização e invariância na alfabetização; aprendizado indireto, conhecimentos prévios e prática da leitura no contexto escolar; plasticidade cerebral e período crítico; diversidade de estimulação, emoção e nível de processamento na consolidação das memórias; atenção e aprendizagem. Defende-se, por fim, a consideração de achados neurocientíficos no ensino de língua materna.Palavras-chave: Neurociências. Educação. Aprendizado. Escrita. ABSTRACT REPERCUSSIONS OF NEUROSCIENTIFIC FINDINGS FOR TEACHING WRITINGThis paper explores some findings of neuroscience considering some implications for education, particularly for the acquisition and learning of writing. The advent of technology has allowed a substantially expansion of the knowledge about the functioning of language in the human brain: how we learn, process, evoke and forget the verbal knowledge. Based on Damasio and Damasio (2004) (2000), we discuss and speculate on some questions: desymmetrization and invariance in literacy; indirect learning, previous knowledge and practice of reading in the school context; brain plasticity and critical period; diversity of stimulation, emotion and level of processing in memory consolidation; attention and learning. It is argued, finally, the importance of taking into consideration the neuroscience findings for the teaching of the mother tongue.

The physiological basis of neurofunctional reorganization in stimulating the nervous system is justified and ratified by the concepts of neuroplasticity and therefore, its use in neonatology is well indicated. Objective: Describe how Neurofunctional reorganization throughPadovan method can contribute to restore neurologic function of newborns and can avoid the need for gastrostomy and shortening hospital stay.Method: Descriptive and retrospective study performed in a hospital at Ceará´s inland, Brazil, through analysis of medical records. 92 patients from the neonatal ICU who suffered perinatal asphyxia and evolved with neurological disorders were evaluated. Patients received Neurofunctional Reorganization therapy, which is the performance of physical and oral exercises that complement each other in order to recover lost functions and also prepare the body to acquire functions and capabilities which it has potential for.Results: Eighty-two patients completed the therapy and showed positive results (89.1%). The main expected outcome was the recovery of suction and this was achieved in between 8 and 150 days. 48 cases showed an improvement between 8 and 30 days of treatment (56%). Conclusions:The Neurofunctional reorganization proposed by Padovan is effective in the recovery of neurological function of newborns, especially the suction, shortening the hospital stay and avoiding gastrostomy.
