Average correlation between LFP signal and MUA signal for all distances

Correlation (mean+/-SD) between the LFP responses (total power) to the 77 objects and the MUA responses to the 77 objects for recording sites separated at varying distances (x-axis).
For sites with distances < 1 mm, the two sites were recorded in the same penetration while for all other sites the correlation coefficients are computed across different penetrations.
