Setor de Neurologia. Rio de Janeiro, RJ, Brasil.The electroencephalogram amplitude spectra at 11 fixed frequencies of intermittent photic stimulation of 3 to 24 Hz were combined into driving "profiles" for 14 scalp points in 8 male and 7 female normal subjects aged 9 to 17 years. The driving response varied over frequency and was detected in 70 to 100% of cases in the occipital areas (maximum) and in 27 to 77% of cases in the frontal areas (minimum) using as a criterion peak amplitude 20% higher than those of the neighbors. Each subject responded, on average, to 9.7 ± 1.15 intermittent photic stimulation frequencies in the right occipital area and to 6.8 ± 1.97 frequencies in the right frontal area. Most of the driving responses (in relation to the previous background) were significant according to the spectral F-test (a = 0.05), which also detected changes in some cases of low amplitude responses not revealed by the peak criterion. The profiles had two maxima in the alpha and theta bands in all leads. The latter was not present in the background spectra in the posterior areas and was less pronounced in the anterior ones. The weight of the profile theta maximum increased towards the frontal areas where the two maxima were similar, while the profile amplitudes decreased. The profiles repeated the shape of the background spectra, except for the theta band. The interhemispheric correlation between profiles was high. The theta driving detected in all areas recorded suggests a generalized influence of the theta generators in prepubertal and pubertal subjects.ElectroencephalogramIntermittent Photic StimulationPhotic DrivingBrain TopographyChildrenAdolescentsEstimulação Luminosa - métodosEletroencefalografia - métodosPotenciais Evocados Visuais - fisiologiaLobo Occipital - fisiologiaLateralidade Funcional - fisiologiainfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da FIOCRUZ (ARCA)instname:Fundação Oswaldo Cruz (FIOCRUZ)instacron:FIOCRUZLICENSElicense.txttext/plain1878https://www.arca.fiocruz.br/bitstream/icict/350/1/license.txt4ab65ca798f15d32db061c8ec1b00ab1MD51ORIGINALTopographic aspects of photic.pdfTopographic aspects of photic.pdfapplication/pdf1592162https://www.arca.fiocruz.br/bitstream/icict/350/2/Topographic%20aspects%20of%20photic.pdfbc774f068173c1416271af1bbfd09f56MD52TEXTTopographic aspects of photic.pdf.txtTopographic aspects of photic.pdf.txtExtracted texttext/plain49245https://www.arca.fiocruz.br/bitstream/icict/350/5/Topographic%20aspects%20of%20photic.pdf.txtb4eec12e85f9297ddd4710dd892fc477MD55THUMBNAILTopographic aspects of photic.pdf.jpgTopographic aspects of photic.pdf.jpgGenerated Thumbnailimage/jpeg2012https://www.arca.fiocruz.br/bitstream/icict/350/4/Topographic%20aspects%20of%20photic.pdf.jpgfa7ea757c2a6bc86f4eb8c75c9e3c740MD54icict/3502023-05-04 14:23:45.359oai:www.arca.fiocruz.br:icict/350Repositório InstitucionalPUBhttps://www.arca.fiocruz.br/oai/requestrepositorio.arca@fiocruz.bropendoar:21352023-05-04T17:23:45Repositório Institucional da FIOCRUZ (ARCA) - Fundação Oswaldo Cruz (FIOCRUZ)false
