🙅🏻♀️ To ensure our results weren't skewed by auditory or somatosensory confounds, we stimulated the left and right primary motor cortex (M1) as a control site. We found no significant changes in behavior after M1 stimulation, confirming that our observed effects were specific to FEF TUS. 🙌🏽

😮 The twist? Individual differences matter. 🧍🏿🧍🏼♀️🧍🏻♂️We show that baseline GABAergic inhibitory tone (measured via MRS) predicts the magnitude of the TUS-induced effects. This highlights how neurophysiological state influences the outcomes of neuromodulation.

🔑 Our key finding: TUS over the FEF excites saccadic behavior, effectively biasing saccades towards the contralateral side. 👀 This confirms that TUS can modulate decision-making circuits in humans in real time. 🔊🧠 More on that soon!
