A neuroscientist proposes a study with two primary goals: 1) to measure the brain's electrical response to a visual stimulus with millisecond-level precision, and 2) to identify the exact, millimeter-specific brain structure where this response originates. Based on the nature of the data captured by EEG electrodes (which measure the frequency and amplitude of brainwaves over time), evaluate the suitability of this technology for achieving both of the researcher's goals. Justify your reasoning for each goal.
