multi-voxel pattern analysis

Multi-voxel pattern analysis (MVPA) is a technique used in brain imaging to examine patterns of activity across many small regions (voxels) in the brain. Instead of just looking at which areas are active, MVPA analyzes the specific combination of signals in multiple voxels to identify patterns associated with different thoughts, feelings, or tasks. This approach helps researchers understand how information is represented in the brain with greater detail and precision, enabling them to decode mental states and study complex cognitive processes beyond what traditional methods can reveal.
