Single voxel autocorrelation reflects hippocampal function in temporal lobe epilepsy.

ABSTRACT: We have previously shown that autocorrelation analyses of BOLD signal applied to single voxels in healthy controls can identify behaviorally-relevant gradients of temporal dynamics throughout the hippocampal long-axis. A question that remains is how changes in the brain's functional and structural integrity affect single-voxel autocorrelation. In this study, we investigate how hippocampal autocorrelation is affected by hippocampal dysfunction by investigating a population of patients with unilateral temporal lobe epilepsy (TLE). Many patients with TLE have mesial temporal sclerosis (MTS), characterized by scarring and neuronal loss, particularly in the anterior hippocampus. Here, we compared patients with left and right TLE, some with and without MTS, to healthy controls. We applied our si
