In this (incredibly late) podcast Ryan and Joel discuss some of the spookier bits of neuroscience. Prior to the start of the main cast, Joel introduces their new plans for upcoming casts which include a focus on interviews and guest hosts.
In this podcast, Ryan and Joel talk about the amazing work of Dr. Ramachandran, who figured out a clever and cost-effective way to treat ‘phantom pain’ in amputated limbs.
Left: Loss of the arm allows nearby sensory regions to ‘take over’ the lack of space
Right: If our body parts were as relatively big as the space devoted to them in terms of cortical area.
Penfield’s homunculus looks super gross, but it shows how sensation coming in from the hands and mouth is the most discriminating touch on our bodies. This makes sense, given that they are the primary tools we use to explore the environment (remember that we use our mouths to inspect new foods, for example, which is crucial to allow us to live!)
Enjoy the podcast!
