Article Synopsis
- - This paper analyzes nine different functional connectivity estimators used in fMRI studies, comparing three existing ones and six new variations to assess their performance in relation to noise and region size.
- - The study demonstrates that the choice of estimator significantly impacts correlation values between brain regions, with some estimators, like correlation of averages (ca), showing biases linked to region size and intra-correlation.
- - A new estimator, local correlation of averages, is introduced that provides better accuracy and lower bias than the ca estimator while maintaining discriminative power, with findings indicating a ventral-dorsal gradient affecting functional network analyses in the brain.
