The possible incorporation of newborn title= jir.2014.0001 neurons at unique relay stations on the neural circuits involved in electrosensory data processing may have functional consequences around the Analysis per cone in Figures 6D,E.Frontiers in Neuroanatomy | www. computational energy with the network and thus, in the functional specialization of G. 00088/abstractVertebrate retina's bipolar cells terminate close for the photoreceptor layer with one polar neurite and to the ganglion cell layer with the other polar neurite. The bipolar cells play the central aspect of neuronal wirings. This observation helped substantiate Cajal's concept with the independent "neuron" because the main structural and functional unit of nervous tissue (Cajal, 1893). Determined by this notion, Polyak (1941) clarified the cellular organization of primate retina. He used the tissue stained by the Golgi approach for title= pnas.1408988111 light microscopy. Each authors, however, could not reveal the precise structure of cellular interfaces. EM in the end revealed the synaptic cleft involving two nerve cell membranes, confirming the neuron doctrine. Nevertheless, identification of person synapses in randomly sampled sections doesn't reveal how neurons are wired into.Orn neurons that migrate tangentially as much as the OB -and thus constitute the anamniote counterpart with the amniote rostral migratory stream- (Adolf et al., 2006; Grandel et al., 2006) or radially to the adjacent Vd and Vv, the teleostean homologous with the amniotes striatum and septum (Ganz et al., 2012; Harvey-Girard et al., 2013). Interestingly, while in mammal striatum doesn't take place neurogenesis "in vivo," and the SVZ offers rise to neuroblasts that migrate towards the OB, striatal ischemic lesions induce the generation of neuroblasts from the SVZ that migrate in chains in to the striatum (Yamashita et al., 2006). The comparative relevance of migration and/or potential neurogenesis in other brain regions (ELL, TS, TeO, and Cb) emerge from their involvement in sensory data processing, motor manage and/or sensory-motor integration. The possible incorporation of newborn title= jir.2014.0001 neurons at diverse relay stations of your neural circuits involved in electrosensory info processing might have functional consequences on the computational energy of the network and as a result, within the functional specialization of G. omarorum brain. In conclusion, within this work we give additional evidences that adult cell proliferation is often a conserved function of euteleosts. Actually, the spatial distribution of adult G. omarorum brain proliferation zones is comparable to closely associated also as phylogenetically distant species within the euteleostean radiation. We also demonstrated the heterogeneous cellular composition of all analyzed G. omarorum adult brain proliferation zones, plus the ubiquitous presence of putative stem cells. Our results also revealed the profuse generation of newborn cells, whose pace of migration varied among proliferation zones. Additional studies in progress, combining double thymidine analog labeling strategy with immunohistochemistry to evidence the expression of neuronal markers or with tract tracing, will reveal the cellular identity of newborn cells. This may permit us to further envisage the functional part of adult cell proliferation and neurogenesis.ACKNOWLEDGMENTSThis work was partially supported by Agencia Nacional de Investigaci e Innovaci (#FCE_2009_1_2246, #FCE_3_2011_1_6168) and Programa para el desarrollo de Ciencias B icas (PEDECIBA).
