We analyse the spatially resolved stellar populations of nine local (z < 0.1) Brightest Cluster Galaxies (BCGs) observed with VIMOS in Integral Field Unit mode. Our sample is composed of seven slow-rotating and two fast-rotating BCGs. We do not find a connection between stellar kinematics and stellar populations in this small sample. The BCGs have shallow metallicity gradients (median Δ[Fe/H] = -0.11±0.1), high central metallicities (median [Fe/H][α/Fe] = 0 = 0.13±0.07), and a wide range of central ages (from 5 to 15 Gyr). We propose that the reason for this is diverse evolutionary paths in BCGs. 67 percent of the sample (6/9) show ∼ 7 Gyr old central ages, which reflects an active accretion history, and 33 percent of the sample (3/9) have central ages older than 11 Gyr, which suggest no star formation since z = 2. The BCGs show similar central stellar populations and stellar population gradients to early-type galaxies of similar mass (Mdyn > 10^11.3M_☉) from the ATLAS3D survey (median [Z/H] = 0.04±0.07, Δ[Z/H] = -0.19±0.1). However, massive early-type galaxies from ATLAS3D have consistently old ages (median Age = 12.0±3.8 Gyr). We also analyse the close massive companion galaxies of two of the BCGs. These galaxies have similar stellar populations to their respective BCGs.
