General Organization of the HF Fields Related to Macroscopic Anatomy

Macroscopically, both premature cases (not illustrated) and newborns have completely formed brains. Telencephalic structures, such as lobules and commissures and the general topography and disposition of the brain are present. The HF lies at the same position as in the adult: at the ventromedial aspect of the temporal lobe. A gross examination of the brain reveals that the full set of macroscopic landmarks is present in the newborn brain. The utility of this group of gross anatomical landmarks in the segmentation of the HF and the surrounding cortex of the parahippocampal region (PHR, namely the cortical areas around the HF, beginning with the temporopolar cortex, and followed in the caudal direction by the perirhinal and posterior parahippocampal cortices) has been reported previously (Insausti et al. 1998b; Insausti and Amaral 2004).
