SPIKE­TIME METRICS ANALYSIS OF ANTERIOR
CINGULATE CORTEX ACTIVITY IN AN
EXPLORATION/EXPLOITATION TASK
ABSTRACT
Anterior Cingulate Cortex (ACC) single units firing rate modulations correlate with the
behavioral policy of monkeys engaged in an exploration/exploitation task. The possible
importance of spike timing is a central issue that remains to be investigated. A well­
designed tool allowing to address it is Victor and Purpura spike train metrics, which
quantifies how dissimilar two spike trains are, as a function of the importance of spike
timing. When analyzed with this method, the data show that adequate spike timing
sensitivity increases the discrimination between the strategy switch moment and ex-
