What brain imaging technique is highlighted in the Canli study?

The Canli study emphasizes the use of functional Magnetic Resonance Imaging (fMRI) as a brain imaging technique. fMRI is particularly relevant because it allows researchers to observe brain activity in real-time by measuring changes in blood flow associated with neuronal activity. In the context of the Canli study, which investigates the neural correlates of emotional memories, fMRI was essential for identifying the specific brain regions activated when participants viewed emotionally charged images. This technique provides a detailed view of brain function and is crucial in understanding how emotions influence memory processes, making it the appropriate choice for this study.

In contrast, CT scans provide static images of brain structures without capturing real-time activity. EEG focuses on electrical activity and temporal resolution rather than the spatial localization of brain functions, making it less suitable for assessing emotional responses linked to memory. Ultrasound is not commonly used for brain imaging in psychological studies, as it primarily assesses soft tissue and blood flow in other medical contexts. Thus, fMRI stands out as the most relevant and effective technique used in the Canli study to explore the relationship between emotion and memory.
