Este protocolo utiliza técnicas de análisis y proyección de imagen (3D) tridimensionales para visualizar y cuantificar las mitocondrias del nervio específico. Las técnicas son aplicables a otras situaciones donde una señal fluorescente se utiliza para aislar un subconjunto de los datos de otra señal fluorescente.

El objetivo general de esta técnica de imagen y análisis es aislar información específica de una señal compleja. Específicamente, este protocolo describe cómo visualizar y cuantificar las mitocondrias específicas del nervio con otras mitocondrias dentro de la epidermis. Este método puede ayudar a responder preguntas clave en el campo de la neurología, como por ejemplo, cómo se comparan las mitocondrias dentro de las fibras nerviosas intraepidérmicas de individuos sanos con las mitocondrias específicas del nervio de pacientes con complicaciones neurológicas.

La principal ventaja de esta técnica es que tomamos una señal compleja y extraemos información específica de ella. Este protocolo nos ayuda a aislar una señal específica, como la señal en estas pajitas, de las señales a su alrededor.
