This book provides an original account of behavioral aspects with important ramifications for the study of transient receptor potential (TRP) channels functioning. It explains, in terms of specified somato-sensory mechanisms and systems, how TRP channels work. Through exploration of animal models by testing paw withdrawal reflexes to thermal and mechanical stimuli, it is shown that TRP channels are promising targets for the development of a new group of analgesic drugs at the periphery and central levels and opportunities for therapeutic intervention.
