To address this, we recorded LFPs and putative fast-spiking interneurons (FSIs) from ventral striatum as rats learned a spatial decision task (Multiple-T) to earn food rewards. The structure of this task allowed us to examine the distribution of LFP patterns relative to decision points, movement initiation, and reward. In a parallel study (van der Meer and Redish, 2009), we examined the activity of putative medium spiny neurons; here we analyzed LFPs and their relationship to FSIs from the same data set.
