How Sound Localization Works: Timing + Intensity Differences | 20th Week in Medical School

My first week of my second semester was great, and I learned so much that I decided to make a second video.

Sound localization is something I first learned about in depth as a biomedical engineering student in undergrad. However, we mostly covered the physics of how sound localization works and why the human brain needs two different methods of determining localization based on whether the sound has a high frequency or a low frequency. I already knew going into medical school that high frequency noises required knowing the volume difference while low frequency noises required knowing the phase shift based on the timing difference.

This past week, I got to learn about the neurocircuitry that our brain uses to determine these volume and timing differences. It is amazing how simultaneously complicated and simple these circuits are that are genetically determined to function in our brains without any conscious effort.

Note: For those that are new here, I'm not a doctor (yet). I'm currently a first year medical student at Duke University.
