We perform discriminative analysis of brain structures using morphometric information. Spherical harmonics technique and point distribution model are used for shape description. Classification is performed using linear discriminants and support vector machines with several feature selection approaches. We consider both inclusion and exclusion of volume information in the discrimination. We perf...

The superficial morphology of the pleura has been observed in humans by scanning electron microscopy (SEM). Pleural samples from the visceral, mediastinal, diaphragmatic and costal normal human pleura were observed, and a thorough morphometric study was performed. The most evident feature was the ubiquitous presence of microvilli and micropores. The secretion and absorption activities therefore...

Morphometric analysis of neurons and brain tissue is relevant to the study of neuron circuitry development during the first phases of brain growth or for probing the link between microstructural morphology and degenerative diseases. As neural imaging techniques become ever more sophisticated, so does the amount and complexity of data generated. The NEuronMOrphological analysis tool NEMO was pur...

To clarify the clinical, neuropathological, and molecular characteristics of spinocerebellar ataxia type 6 (SCA6), two unrelated Japanese families with SCA6 were studied. A clinical feature of the two families was late onset "pure" cerebellar ataxia. Pathologically, three SCA6 brains consistently showed Purkinje cell dominant cortical cerebellar degeneration. Morphometric analysis showed that l...

Gifted children are able to learn in a more advanced way than others, probably due neurophysiological differences the communication efficiency neural pathways. Topological features contribute understanding correlation between brain structure and intelligence. Despite decades of neuroscience research using MRI, methods based on region connectivity patterns limited by MRI artifacts, which therefo...

Vibrissae (whiskers) are important components of the mammalian tactile sensory system, and primarily function as detectors of vibrotactile information from the environment. Pinnipeds possess the largest vibrissae among mammals and their vibrissal hair shafts demonstrate a diversity of shapes. The vibrissae of most phocid seals exhibit a beaded morphology with repeating sequences of crests and t...

OBJECTIVE Acromegaly is frequently associated with altered facial appearance at the time of diagnosis. Furthermore, acromegaly is also associated with adverse psychological outcomes. We conducted a single-centre, cross-sectional study comparing patients with growth hormone vs non-functioning pituitary adenomas (NFA) to assess the association between morphometric changes and psychological outcom...

in this paper, the performance of 11 different distances for image retrieval and classification, based on color, shape and texture, is evaluated. the precision-recall measure and the correct classification rate of the k-nn classifier are used to evaluate retrieval and classification performances, respectively. the experimental results for a database of 1000 images from 10 different semantic gro...

background: the rodent somatosensory barrel cortex is an ideal model to examine the effect of experience-dependent plasticity on developing brain circuitry. sensory deprivation such as whisker deprivation may affect neuroanatomical aspects of the brain during developmental processes. the present study designed to investigate the possible effects of whisker deprivation on the morphometric charac...
