Elsa Fouragnan is an Associate Professor and UKRI Future Leader Fellow at the University of Plymouth. We talk mainly about her work on focussed transcranial ultrasound stimulation, a new non-invasive way other stimulating (human) brains, including deep areas that can't be reached with TMS. We also discuss her childhood in French Polynesia, how she started doing research, what it's like seeing a brain during surgery, and much more.
This was the first episode I recorded in-person. The audio quality is really good, with the minor exception that I made a really silly error during editing, such that quiet parts are sometimes not entirely audible. A few words are not audible, but this shouldn't affect comprehension.
BJKS Podcast is a podcast about neuroscience, psychology, and anything vaguely related, hosted by Benjamin James Kuper-Smith.

The Brothers Ortiz
The Brothers Ortiz is the story of two brothers–both successful, but in very different ways. Gabe Ortiz becomes a third-highest ranking officer in all of Texas while his younger brother Larry climbs the ranks in Puro Tango Blast, a notorious Texas Prison gang. Gabe doesn’t know all the details of his brother’s nefarious dealings, and he’s made a point not to ask, to protect their relationship. But when Larry is murdered during a home invasion in a rented beach house, Gabe has no choice but to look into what happened that night. To solve Larry’s murder, Gabe, and the whole Ortiz family, must ask each other tough questions.
