Various aspects of the present subject matter relate to a method and a device. In various embodiments of the method, a neural activity signal is sensed, a feature from the sensed neural activity signal is extracted, and a neural marker for the extracted feature is created. The neural marker includes information regarding the extracted feature. In various embodiments, the device comprises a port to receive a neural activity signal, and a feature extractor adapted to receive and process the neural activity signal to produce a neural marker that includes information for the neural activity signal. In various embodiments, the device comprises a display, a memory adapted to store a neural marker associated with a sensed neural activity signal, and a controller adapted to communicate with the memory and the display to provide a representation of the neural marker on the display. Other aspects and embodiments are provided herein.
