“…Since its discovery, SCGN has been widely studied in the brain of different species. Some studies show SCGN distribution in the whole brain, for example in fishes ( Basu et al, 2022 ), birds ( Gáti et al, 2014 ) or rats ( Maj et al, 2012 ), but most of them focus on a specific brain area. In addition to the studies mentioned above, SCGN expression has been analyzed in different species in the amygdala, ( Mulder et al, 2010 ; Gyengesi et al, 2013 ; Hevesi et al, 2021 ), the olfactory bulb ( Mulder et al, 2009 ; Kosaka and Kosaka, 2013 ; Ortiz-Leal et al, 2023 ), or the hippocampus ( Attems et al, 2007 ; Tapia-González et al, 2020 ), among others.…”
