Serotonin (5-HT) is known to induce a wide range of short-term and long-term (or delayed) effects. In the present paper we demonstrated that short time-window application of the 5-HT precursor 5-hydroxytryptophan during early cleavage stages results in both irreversible morphological malformation (exogastrulation) and distinct changes in behavior of young(More)
The neural crest represents a highly multipotent population of embryonic stem cells found only in vertebrate embryos. Acquisition of the neural crest during the evolution of vertebrates was a great advantage, providing Chordata animals with the first cellular cartilage, bone, dentition, advanced nervous system and other innovations. Today not much is known(More)
Serotonin (5.HT) is known to be functionally active during early development in both vertebrates and invertebrates. However, the presence of 5-HT and its synthesis and transport system has not yet been demonstrated in bivalve early development. The presence of 5-HT was immunochemically demonstrated at the cleavage stage of bivalve Mytilus trossulus. 5-HT(More)
Cultured cerebellar granule neurons (CGNs) are resistant to the toxic effect of ZnCl2 (0.005 mM, 3 h) and slightly sensitive to the effect of kainate (0.1 mM, 3 h). Simultaneous treatment of CGNs with kainate and ZnCl2 caused intensive neuronal death, which was attenuated by external acidosis (pH 6.5) or 5-(N-ethyl-N-isopropyl)amiloride (EIPA, Na+/H+(More)
In a case study on development of larvae of Trochozoa species of different systematic positions, it was shown that peripheral neurons differentiated firstly. According to the characters of early peripheral neurons, in particular their localization in parts that differed from known zones of appearance of central ganglia, the difficult periphery of processes(More)
