“…Cynomolgus monkeys exhibited a regular sequence of formations of the primary sulci and gyri similar to those in humans. Thus, the emerging patterns of the primary sulci and gyri may be phylogenetically conserved between humans and the Old World monkeys, whereas the patterns are altered by genetic or vascular factors (Maudgil et al 1998). The primary sulci are known to be stable within and among primate species (Weiss and Aldridge 2003) and correspond with cytoarchitectural, myeloarchitectural and/or thalamocortical borders (Maudgil et al 1998).…”

This study aimed to clarify the development of sulci and gyri on the external surface of the cerebrum of cynomolgus monkeys. Sulcus formation began with the appearance of the lateral fissure on embryonic day (ED) 70, followed by delineations of four cerebral lobes by the emergence of the parietooccipital sulcus, central sulcus, and preoccipital notch on EDs 80-90. The following primary sulci were then visible until ED 120: the superior temporal sulcus on ED 90; the intraparietal sulcus, lunate sulcus, inferior occipital sulcus, and arcuate sulcus on ED 100; and the principle sulcus on ED 110; the occipitotemporal sulcus, anterior middle temporal sulcus, and superior postcentral dimple on ED 120. These sulci demarcated the superior temporal gyrus on ED 90, the precentral gyrus, supramarginal gyrus, and angular gyrus on ED 100, and the inferior and middle temporal gyri, postocentral gyrus, superior parietal lobule, superior, middle and inferior frontal gyri, and inferior occipital gyrus on ED 120. Except for the intermediate and lateral orbitofrontal sulci, the sulci that appeared on ED 130 and thereafter were not related to the gyrus demarcations. Intriguingly, the brain markedly gained weight on EDs 100 and 120, corresponding to the embryonic ages when almost all gyri were visible. The results suggest that a rapid growth of the cerebrum involves convolutions of the gyri by a regular sequence of the sulcus formation in cynomolgus monkeys. This study further provides a standard of reference for normal development in the cerebral cortical morphology of cynomolgus monkeys.

“…Although the adult brain shows a high degree of symmetry for prominent cortical gyri and sulci (Maudgil et al 1998;Dale et al 1999;Fischl et al 1999), variations in surface morphology and asymmetries of transmitter systems occur (Hutsler et al 1998;Kovacs et al 1998;Nopoulos et al 2000;Watkins et al 2001;Sowell et al 2002). Cortical morphology varies with age and with the pathological state of the patient (Kitagaki et al 1998;Symonds et al 1999;Resnick et al 2000;Narr et al 2001a,b;Tang et al 2001;Hardy and Selkoe 2002).…”

The use of human brain tissue obtained at autopsy for neurochemical, pharmacological and physiological analyses is reviewed. RNA and protein samples have been found suitable for expression profiling by techniques that include RT-PCR, cDNA microarrays, western blotting, immunohistochemistry and proteomics. The rapid development of molecular biological techniques has increased the impetus for this work to be applied to studies of brain disease. It has been shown that most nucleic acids and proteins are reasonably stable postmortem. However, their abundance and integrity can exhibit marked intra-and intercase variability, making comparisons between case-groups difficult. Variability can reveal important functional and biochemical information. The correct interpretation of neurochemical data must take into account such factors as age, gender, ethnicity, medicative history, immediate ante-mortem status, agonal state and post-mortem and post-autopsy intervals. Here we consider issues associated with the sampling of DNA, RNA and proteins using human autopsy brain tissue in relation to various ante-and postmortem factors. We conclude that valid and practical measures of a variety of parameters may be made in human brain tissue, provided that specific factors are controlled.

“…in Voxel Based Morphometry [15]. For more specialised applications hybrid approaches may be required; for example cortical matching may be improved -or at least better controlled -by exploiting work done by Maudgil et al [16] where 24 points which were determined to be homologous between subjects were identified on the cortical surface. Such points can be incorporated into voxel-based registration algorithms [17].…”

Abstract. Non-rigid image registration is widely used in the analysis of brain images to the extent it is provided as a standard tool in common packages such as SPM. However the performance of algorithms in specific applications remains hard to measure. In this paper a detailed comparison of the performance of an affine, B-Spline control-point and viscous fluid registration algorithm in inter-subject brain registration is presented. The comparison makes use of highly detailed expert manual labellings of a range of structures distributed in scale and in location in the brain. The overall performance is B-Spline, fluid, affine (best first) with all algorithms struggling to improve the match of smaller structures. We discuss caveats, evaluation strategies for registration and implications for future registration-based neuroimaging studies.
