Any of the terminal or smaller branches of an axon that terminates with specialized ending that releases neurotransmitters. Telodendria originally refer to the terminal branches of dendrites, now they refer to the main or terminal arborization of an axon. Word origin: Greek tÃ©los (end) + Greek dÃ©ndron (tree).
Permineralization is one of the ways in which a plant or animal can be turned into a fossil. During this process, mineral rich water seeps into the void spaces of an organism, leaving deposits of minerals behind that slowly build up, creating a cast of the organism.
Periventricular heterotopia (PH) has been interpreted as a disorder in neuronal migration where newly born neurons fail to migrate from their birthplace along the lining of the lateral ventricles of the brain, thereby giving rise to the characteristic ectopically placed neuronal nodules (figure 1â).
