Le conoscenze sull’evoluzione del sistema nervoso sono piuttosto limitate, perché si tratta di un tessuto raramente conservato nei documenti fossili. Ciò che si sa sulla sua evoluzione si basa sull’interpretazione dell’anatomia e della genetica molecolare di gruppi più recenti. Tuttavia, questa interpretazione è limitata, dato che gli animali odierni sono più derivati. Lo scopo di questo studio è stato quello di descrivere l’evoluzione del sistema nervoso in termini di complessità. È stata effettuata una revisione bibliografica di libri e periodici. Si è capito che gli organismi, fin dai tempi più remoti, devono adattarsi costantemente all’ambiente per sopravvivere e le loro comunicazioni neuronali, chiamate sinapsi, sono alla base di processi complessi come il movimento e l’apprendimento. Nel corso dell’evoluzione, si è capito che i principali cambiamenti nel livello di complessità del sistema nervoso erano legati al numero di neuroni. Gli organismi più complessi, come l’uomo, hanno un numero maggiore di neuroni.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    Lesley J. Rogers / Lesley JRogers
    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...

    Das Wissen über die Evolution des Nervensystems ist recht begrenzt, da es sich um ein Gewebe handelt, das nur selten in fossilen Aufzeichnungen erhalten ist. Was über seine Entwicklung bekannt ist, beruht auf der Interpretation der Anatomie und Molekulargenetik jüngerer Gruppen. Diese Interpretation ist jedoch begrenzt, da die heutigen Tiere eher abgeleitet sind. Ziel dieser St...

  • The Phylogenetic Evolution of the Nervous System
    Ana Maria da Silva Curado / Maria Francisca Da Silva Aguiar
    Knowledge about the evolution of the nervous system is quite limited, because it is a tissue that is rarely preserved in fossil records. What is known about its evolution is based on the interpretation of the anatomy and molecular genetics of more recent groups. However, this interpretation is limited, given that today’s animals are more derived. The aim of this study was to de...
