Don't get me wrong, I would love this finding to be replicable, it would be pivotal as what other nerves could we stimulate to change perception (think pain, mental health issues, loss of senses).

There's quite a lot of research in this direction (stimulation, be it ultrasound or otherwise) to tackle exactly things you mention. Not completely sure but probably stimulators to suppress epilepsy are the most common. It has been proven in animal research stimulating the right area induces visual stimuli - IIRC this has been tested and confirmed in humans as well, i.e., make people see again. And there's more going on.

In the end: everything in the brain is electrical current. Meaning that in theory stimulating the right bits can do pretty much everything.
