Abstract
Prave koštunjače su kao filogenetski najstarija skupina kralježnjaka, zadržale najveću sposobnost neurogeneze, plastičnosti mozga te regeneracije centralnog živčanog sustava. Neurogeneza i plastičnost mozga mijenjaju se u odnosu na način života i okoliš u kojem ribe žive, što se očituje i kroz veliku morfološku raznolikost. Obogaćenje okoliša potiče plastičnost mozga i povećava razinu proliferacije stanica u pojedinim regijama mozga te pospješuje dugoročne potencijacije u hipokampusu. Na staničnoj razini, važnu ulogu ima reverzibilno polisijalizirana NCAM molekula koja djeluje na formaciju i remodeliranje sinapsi, rast i navođenje aksona i dendrita te neurogenezu. Ključna je u regulaciji između plastičnosti i sinaptičke povezanosti, a njezina distribucija u pojedinim regijama mozga prilagođena je na ekološku nišu koju ribe zauzimaju. Morfologija mozga usko je povezana s ponašanjem riba. Različitim osjetnim sustavima procesuiraju informacije iz okoline te se prilagođuju zadanim selekcijskim pritiscima, što rezultira strukturalnim i neurofiziološkim promjenama u mozgu.
Abstract (english)
eleostei is phylogenetically the oldest group of vertebrates, and have kept the highest ability of neurogenesis, neural plasticity and regeneration of the central nervous system. Neurogenesis and brain plasticity are closely affected with fish lifestyle and the environment they live in, which results in great morphological diversity. Environmental enrichment promotes brain plasticity and increases cell proliferation in the hippocampus. At the cellular level, reversibly Polysialylated NCAM plays a key role in neurogenesis, synapses formation and remodeling, growth and bifurcation of axons and dendrites. It is important in regulation between brain plasticity and connectivity and its distribution in specific regions is modified with the ecological niche in which the fish lives. Brain morphology is closely related to fish behavior. They process the information from their environment with different sensory systems and accordingly adapt to selective pressures. This results in structural and neurophysiological changes in brain structures.
