In recent years, investigators have explored alterations in brain activity due to the passage of a small current through the brain via electrodes placed on the scalp, with intriguing results related to memory and cognition. In one study, electrodes on the scalp created a 1.0 V/mV/m electric field in the brain tissue and caused a 1.0 mAmA current to pass through a 2.5×10−3m22.5×10−3m2 cross-section area of the brain. What resistivity does this imply for the brain tissue ? i got the answer 2.5 ohms/m but i wanna double check if it is correct thank you in advanced
