Libelle of note

The Pars compacta may be further subdivided into two parts or tiers, each with subnuclei (Braak H, Braak E 1986 Nuclear configuration and neuronal types of the nucleus niger in the brain of the human adult. Human Neurobiol 5:71-82; van Domburg PHMF, ten Donkelaar HJ 1991 The human substantia nigra and ventral tegmental area. Adv Anat Embryol Cell Biol 121:1-130); here, the subdivision by Halliday G, Reyes S, Double K (2012 Substantia nigra, ventral tegmental area and retrorubral fields. In: Mai JK, Paxinos G, eds: The Human Nervous System, 3rd ed. Elsevier, Amsterdam, pp 439-455) is used. The various subnuclei partly correspond to the subdivision into Nigrosomes and Matrix (Damier P, Hirsch EC, Agid Y, Graybiel AM 1999 The substantia nigra of the human brain. I. Nigrosomes and the nigral matrix, a compartmental organization based on calbindin D28k immunohistochemistry. Brain 122:1421-1436).

The two 'Olfactory gyri' in TA suggested their presence as clearly identifiable structures; this is not true. These terms remained from the classic description of the Rhinencephalon (see Gastaut H, Lammers HJ 1961 Anatomie du rhinencéphale. Masson, Paris) and have been deleted. The Cortex piriformis or Cortex olfactorius primarius is the real Olfactory cortex, and can be divided into Frontal and Temporal parts (Allison AC 1954 The secondary olfactory areas in the human brain. J Anat (Lond) 88:481-488; Heimer L, de Olmos J, Alheid GF, et al. 1999 The human basal forebrain, Part 2. Handb Chem Neuroanat 15:57-226).

De Olmos (de Olmos J 1990 Amygdala. In: Paxinos G, ed: The Human Nervous System. Academic Press, San Diego, CA, pp 583-710) introduced the term 'Olfactory amygdala' for the 'Superficial cortex-like amygdaloid region' (Yilmazer-Hanke DM 2012 Amygdala. In: Mai JK, Paxinos G, eds: The Human Nervous System, 3rd ed. Elsevier, Amsterdam, pp 759-834).
