neuronal group selection theory motor development

discuss how factors related to the individual, the task, and the environment affect the organization and control of movement. Evidence is accumulating that abundance in cerebral connectivity is the neural basis of human behavioral variability (ie, the ability to select, from a large repertoire of behavioral solutions, the one most appropriate for a specific situation). The Neuronal Group Selection Theory (NGST) could offer new insights into the mechanisms directing motor disorders, such as cerebral palsy and developmental coordination disorder. These networks, consisting of thousands of strongly interconnected neurons, are called neuronal groups and considered as functional units. Diversity and regularity in infant crawling with typical development. The Neuronal Group Selection Theory (NGST) could offer new insights into the mechanisms directing motor disorders, such as cerebral palsy and developmental coordination disorder. Hadders-Algra, M.

It raises fundamental questions about prevailing assumptions in the field and proposes a new theory of the development of cognition and action, unifying recent advances in dynamic systems theory with current research in neuroscience and neural development. It is a video-based assessment for infants aged 3 to 18 months, or rather until the age of walking independently for a few months. 1 author. Developmental . According to NGST, normal motor development is characterized by two phases of variability. During the phase of primary variability the infant displays variable motor behaviour, but is not able to adapt motor behaviour to the specifics of the situation.

Neural Darwinism and Consciousness 3 Abstract Neural Darwinism (ND), also called the Theory of Neuronal Group Selection (TNGS) is a biological theory of brain development and function which is based on evolutionary and. In addition to the neuronal maturation theory and the dynamic systems theory, there is a third theory, the neuronal group selection theory (NGST) , which combines the "nature" part of the neural-maturationist theories with the "nurture" part of the dynamic systems theory. The Neuronal Group Selection Theory (NGST) could offer new insights into the mechanisms directing motor disorders, such as cerebral palsy and developmental coordination disorder. Variation is not at random but determined by criteria set by genetic information. A compromise between the first two is the Neuronal Group Selection Theory, which views development as the result of a complex intertwining of information from genes and environment. Three phases/processes during neural map development are considered.

It occurs in a variety of domains and a wide range of theories makes understanding children's development a challenging undertaking. Nowadays it is assumed that motor control of rhythmical movements like locomotion, respiration, sucking, and mastication is based on so-called central pattern generators (CPGs): neuronal networks which can generate complex basic activation patterns of the muscles without any sensory signals.
