In an aspect, a method for dynamically measuring temperature variations in skin tissue includes providing one or more electrical signal pickup elements on the skin tissue providing at least one thresholding device to generate one or more agitating signals providing at least one agitating device on the skin tissue at least some distance from the one or more electrical pickup signal elements the method comprising: stimulating the skin tissue by applying one or more agitating signals to the agitating element until a neural response is indicated on a display, the neurons responding with a specific frequency modulation identifying the relevant neural signal by locking on the modulation period and, processing the neural signal to generate the temperature of the skin at the point of the thresholding device.
