Annotation: The book is a collective monograph that discusses several important  issues of cerebrospinal cooperation and interactions. The morphological and  functional study of the cerebral and cerebral cortex and their interaction are  fundamental for the interpretation of the clinical phenomenology of cortical  degenerations in the initial stage of the disease. 

In addition, the analysis of the cerebral-cerebellar interactions strongly supports  the concept of close functional unity and harmonization of the cerebral cortex and  cerebellum. The important role that the cerebral cortex plays in the fulfilment of  higher mental abilities, creativity, emotional processes and homeostatic balance  of the human body is emphasized.

Dynamic of Praxis Functions in the Context of Maturation of the  Parietal and Frontal Brain Regions in the Period 4–6 Years of Age

by Neli Vasileva and Jivko Jekov

Abstract: In recent years, child neuropsychology has paid special attention to  ontogenesis and trends in the development of practical functions during the  preschool period, given their relationship to practical skills and children’s  readiness to learn. On the other hand, the dynamics of complex types of praxis is  an indicator of the integration between the brain regions responsible for the  perception, programming and recoding of motor patterns. The article presents a  comparative analysis of data from a study of two types of praxis functions  (dynamic praxis and spatial postural praxis) in children with typical development in the period 4–6 years. The specificity of the performance of neuropsychological  tests is an indicator of the functioning and the degree of neuronal connectivity of  the parietal and premotor regions of the left hemisphere. The data from the study  show a similar trend in the dynamics of the studied functions and the influence  on them of three independent factors: age, social conditions (type of settlement)  and gender. Significant improvement in the performance of the tasks is observed  in children at the age of 6, which is a reason to consider this age as critical for the  maturation and neurophysiological connectivity of the structures of the parietal  and premotor regions. The assessment of complex types of praxis in this period  is an objective indicator of the neuropsychological development of children and  has an indisputable prognostic effect for future learning disorders.
