We're going 21st Century:
I'm pulling out all the stops this year. First, it was pipe cleaners; Now, YouTube. Sometimes, my jokes become a reality...
I was assigned to teach my group about the various aphasias a patient might present with following a stroke. Aphasias are disorders related to language. Some aphasias inhibit one's ability to speak, others inhibit one's ability to understand speech, etc... Aphasias come in all flavors and are absolutely fascinating to observe and ponder the electrical processes going awry in the brain to produce the apparent disorder.
Enjoy!
