Telencephalon cytoarchitecture in Serranus scriba.

Cytoarchitectural analysis of the telencephalon in Serranus scriba fish enabled us to differentiate a rather specialized morphological structure. Nerve cells identified in this structures cannot be classified following classical categories met in higher vertebrates neither be related to the isodendritic type of nonspecialized neurons. A centripetal orientation of dendrites and exons from all regions to the striatum is clearly expressed. Numerical prevalence of large cells is remarkable for similar structures in mammals in their prenatal and postnatal ontogenesis.
