A team of neuroscientists is developing a new medication intended to improve cognitive function. Their primary research goal is to observe how the drug affects blood flow and activity in specific regions of a living, functioning human brain in real-time, without resorting to invasive procedures. Which of the following research methods would be the most suitable for achieving this specific objective?

In Vitro Methods as Alternatives to Animal Testing

Microdosing as an Alternative to Animal Testing

Noninvasive Imaging as an Alternative to Animal Testing

Computational Methods as Alternatives to Animal Testing
