This week was dedicated to the auditory system, one that is as complex as the visual system and that is not completely understood. The main functioning principle of the transducing process is quite well comprehended at the point that the most advanced sensorial artificial system is auditory; however, the neural paths of the system are more difficult to follow and then to understand.
Maybe the most interesting fact for me was to learn about the mechanisms that are used to process the frequency of the sounds. It seems really complicated how our brain is able to separate and process sound at its more basic characteristics, and then recognize and react to noises and sounds that are very complicated and mixed in the context. The phase locking and tonotopy maps are the main mechanisms for frequency processing and they work for different frequency bands. And, together with the sound localization mechanisms are the main functionalities of auditory neurons. It is incredible to realize that our relations with sound could be really complicated as with music, or the alarms systems, and both are processed in the same simple and basic way, at least at the beginning of the process. I think that there are still a lot to discover and know about the auditory system and how we relate with sound.
