Motor development: changing patterns, growing complexity

Activity-dependent development of calcium regulation in growing motor axons.

In cultured nerve cord explants from the crayfish (Procambarus clarkii), the normal impulse activity levels of growing motor axons determine their response to Ca2+ influx. During depolarization or Ca2+ ionophore application, normally active tonic motor axons continue to grow, whereas inactive phasic motor axons retract and often degenerate. To determine the role of Ca2+ regulation in this diffe...

The cerebellum: from development to structural complexity and motor learning

The cerebellum coordinates motor activities to be performed or that are already underway. In fact, it is very well known that cerebellar damage produces disturbance in movements and in body support. The relationship between cerebellum and motor learning was first suggested with the studies of Ramón y Cajal (1911), Dow and Moruzzi (1958), and Eccles et al. (1967). Dow and Moruzzi (1958) hypothes...

Changing Patterns of Consumption

When mutual developed and developing world accusations of overpopulation and overconsumption are analyzed, several levels of confusion can be pointed out. Since proposals to change global patterns of consumption come from different and even conflicting sources, they should be the object of careful consideration. Changes in consumption influence employment, and therefore they could be detrimenta...
