We studied a sample of 1672 galaxies in regions where a GRB event had occurred, in order to determine if the galactic environment plays a significant role on these energetic events. The Luminosity Function distribution for these galaxies shows some interesting features. For instance, there is a decline on the Luminosity Function at Mr~ −20.5; a lack of flatness at Mr~ −14 and higher-than-expected values of Φ(Mr) for Mr < −22.5. A comparison between our data and the Void, Wall and Early galaxies Luminosity Function was performed.
