This episode is about neural networks on noradrenaline- or the more modern term, norephinephrine- the key neuromodulator known to flip almost every switch in the brain! Drs. Esteban Oryarzabal and Connor Wander break down how noradrenaline, or norepinephrine help regulate brain states useful for attention and task-switching. The studies here cover a whole new way to interpret brain imaging studies, which could have huge implications for neuroscience everywhere!
Please note that this episode is special- it’s a preview from research that hasn’t fully undergone peer review. This means that the findings discussed are still highly preliminary, and could be subject to change. That being said, it’s an incredible body of work!

We want your updates on today’s scientific research directly from the source: straight from the scientist working hard to make new discoveries about our world.
Straight from a Scientists helps you learn the what, the why, and the how of the research we produce every day.
Informal interviews probe deep into how science is done, and why the how matters when it’s time to interpret the results. Roundtable discussions introduce you to hot new fields of study or investigate the darker sides of science.
