Abbreviations used for the  monkey

In naming structures in the macaque monkey brain, the atlas follows what is established English usage and as far as possible is consistent with the terminology applied in other mammalian species. The names of structures and their abbreviations derive from a number of archival sources and no novel names or abbreviations have been created. Gyri and sulci of the cerebral hemisphere are named according to Von Bonin and Bailey (The Neocortex of Macaca Mulatta, 1947). The delineation of areas of the cerebral cortex derives from many sources that deal with the various regions of the cortex, including: Amaral et al. (J Comp Neurol 1987, 264:326), Burton and Jones (J Comp Neurol, 1976, 168:249), Carmichael and Price (J Comp Neurol, 1994, 346:366), Desimone and Ungerleider (J Comp Neurol, 1986, 248:164), Felleman and Van Essen (Cerebral Cortex, 1991, 1:1), Jones et al. (J Comp Neurol, 1978, 181:291), Mesulam and Mufson (Cerebral Cortex Volume 4, 1985, p.179), Seltzer and Pandya (J Comp Neurol, 1989, 290:451), Vogt et al. (J Comp Neurol, 1987, 262:256). In the basal ganglia Heimer et al. (Handbook of Chemical Neuroanatomy, Volume 15 Part III, p. 57) were followed. In the thalamus the nomenclature is that of Jones (The Thalamus, Second Edition, 2007). In the hypothalamus and adjacent regions the nomenclature is mainly derived from Saper (The Human Nervous System, Volume 17, 2004, p.513). In the brainstem primarily Olszewski and Baxter (Cytoarchitecture of the Human Brain Stem, 1982) were followed, with additional names derived from Berman (The Brain Stem of the Cat, 1968).

Currently, the high resolution images of coronal sections of the rhesus monkey brain and the lower resolution atlas made from the same sections are fully labeled using these abbreviations and labeling of the sagittal and horizontal series of sections is currently underway.
