Is there the possibility to modulate a stimulus (by changing frequencies and duration) and set a direct relationship between that stimulus and a certain muscle AP? Telling it otherwise, applying the same stimulus (maintaining the same frequency and duration), again and again, on the same alpha neuron, I will have the same effector contraction (with plenty of time to relax between stimulus)? If the answer is yes, it is possible to build a matrix with different stimulus and correlated muscles AP's?
Hi Paulo,
If I understand your question correctly, the answer is yes. With superthreshold stimulation of the alpha motor neuron and plenty of time between stimuli the muscle AP recorded should be quite standard representing in amplitude and time characteristics number of muscle fibers within given NM unit, their type (slow/fast) and sinchronicity of their activation.

Based on my studies, I say to you that if we think of an external stimulus such as an electrode in a particular brain region can say that there is some correlation "stimulus-response".
About the question "Is there The Possibility to modulate the stimulus (by changing frequencies and duration) and set it direct relationship between stimulus and A Certain que muscle AP?", The answer is Yes, if you are sure you are stimulating this muscle. Yes, it is possible to build a model for an array of different stimuli to different muscles. In this model it is also possible to change frequency and duration.
Si existe esa correlación directa porque el organismo está diseñado para dar respuestas efectoras a determinados estímulos que provienen del exterior o el interior del cuerpo humano; por ejemplo cuando un atleta ha recibido una sobrecarga de entrenamiento su organismo puede responder de diferentes formas en correlación al estímulo que llega al cerebro; una respuesta puede ser colapsar durante las practicas o las competencias, esa es la respuesta que busca el organismo para defenderse en esos momentos del estímulo que le llega, esa respuesta efectora es una respuesta protectora del organismo.
También el organismo puede responder ante este estimulo variando la conducta psicológica de los atletas, como la apatía, trastornos en el sueño, entre otros. Esto dependerá en gran medida del tipo de predisposición competitiva que tenga el sujeto en cuestión y así será entonces su respuesta efectora ante este estimulo.
Dear Sir
If i have understood your question properly then answer is yes. all physiological parameters are responded similar to stress& strain relationship. it is simple linear positive cor-relationship. It is true in your case also. pcg,Chennai
