MIT paper lays out how focused ultrasound could test theories of consciousness

Researchers affiliated with MIT argue that transcranial focused ultrasound—a noninvasive technique that can modulate activity in deep brain regions—could enable more direct, cause-and-effect tests of how conscious experiences arise. In a “roadmap” review in *Neuroscience & Biobehavioral Reviews*, they describe experimental approaches aimed at distinguishing between competing accounts of where and how awareness is generated in the brain.
Researchers at MIT have mapped a previously underappreciated brain circuit that alters how visual information is processed depending on an animal’s level of arousal and movement. In a study in mice, they show that the prefrontal cortex sends specialized feedback signals to visual and motor regions, tightening or loosening visual representations according to behavioral state, as reported in Neuron.

A recent MIT study suggests that artificial intelligence could currently displace up to 12% of the total US jobs market. This equates to one in nine workers potentially affected. The findings highlight ongoing concerns about AI's impact on employment.
