Temporal resolution in neuroimaging

Temporal resolution in neuroimaging refers to the ability to measure changes in brain activity over time. It indicates how quickly a technique can capture dynamic processes in the brain. For instance, methods like electroencephalography (EEG) offer high temporal resolution, allowing researchers to see brain activity in milliseconds. In contrast, techniques like fMRI have lower temporal resolution, capturing changes over seconds to minutes. High temporal resolution is crucial for understanding fast cognitive processes, such as attention or decision-making, while lower temporal resolution may be sufficient for studying slower changes like overall brain connectivity.
