Description
The olfactory tubercle and terminal islands are part of the basal forebrain, a brain area
characterized by great structural heterogeneity. The connectivity and function of the
olfactory tubercle have been evaluated using diffusion imaging and fMRI, however the
precise boundaries within 3D space are still not clarified (Zelano et al., 2007; Echevarria-
Cooper et al., 2022). In addition, it is particularly challenging to study these aspects of
terminal islands due to their small size, complex shape and scattered arrangement in the
basal forebrain (Meyer et al., 1989). Therefore, we have generated cytoarchitectonic maps
of the olfactory tubercle and terminal islands in order to determine their localization in the
stereotaxic space and intersubject variability. Moreover, we provided a 3D reconstruction of
the Great Terminal Island (GTI) in the BigBrain, to define its anatomical features.
