Neurological wiring

It s estimated that each cortical neuron has an average of 10,000 synapses with other neurons near and far. But these connections do not develop all at once. They are formed in the brain during fetal development, infancy, childhood, and even adulthood. The simple fact that the gross anatomy of a child s nervous system is not completely developed until about n or 12 years of age is another refutation of the idea that neurological wiring is complete at birth and therefore uninfluenced by environment. 

However, if a man smokes, eats to the point of obesity, and has elevated blood glucose and elevated blood pressure, his peripheral nervous system wires do not respond adequately to the let s have intercourse signal from the brain—in other words, neurological innervation of the penis is rendered faulty, usually by diabetes (Fig. 14—12). Furthermore, there may not be much pressure in the plumbing — there may be atherosclerosis of the arterial supply of the penis from hypertension and hypercholesterolemia—when cGMP says relax the smooth muscle and let the... 

Understanding how the nervous system is wired up during development is important for understanding both how neurological disorders based on wiring defects can be avoided, and how axons can be made to regenerate appropriately after injury. In the past 15 years or so several families of guidance molecules... 

It is absolutely necessary to consider all the materials used in the device so that interactions can be evaluated. For example, modern cardiac and neurological leads may be insulated with silicone rubber or polyether polyurethane. They also contain metallic conductors (typically MP35N, and sometimes also platinum or silver). The individual conductor wires may be covered with a redundant insulation such as eTFE. The conductors and insulation are connected to stainless steel connector pins and platinum electrodes.
