 +  <a href=/​reference/​bcifun_latidx><​font color=green>​BCIFUN_LATIDX</​font></​a>​ extracts alpha power, computes the alpha lateralization index 
 +  and sends a command to an external device
 + 
 +  This function computes the lateralization index log(A/B) for the
 +  average alpha power in right channels A and the average alpha power
 +  in left channels B. In a covert attention experiment we expect
 +  higher values for attention to the right visual hemifield and lower
 +  values for attention to the left visual hemifield.
