High-resolution MRI data of the brain of C57BL/6J and BTBR mice in three anatomical views

For centuries scientists have been fascinated with the question of how the brain works. Investigators have looked at both where different functions are localized and how the anatomical microstructure varies across the brain surface. Here we discuss how advances in magnetic resonance imaging (MRI) have allowed in vivo visualization of the fine structure of the brain that was previously only visible in post-mortem brains. We present data showing the correspondence between definitions of the primary visual cortex defined anatomically using very high-resolution MRI and functionally using functional MRI. We consider how this technology can be applied to allow the investigation of brains that differ from normal, and what this ever-evolving technology may be able to reveal about in vivo brain structure in the next few years.

The Brain

Background: The frontal lobes make up two-thirds of the human brain, and their functions have long remained unclear. Aim of the work: measuring cortical thickness and volume in various parts of the frontal lobe in athletic football players and non-athletes, as well as age-related changes in both sexes, using high-resolution MRI. Subjects and methods: A 40 volunteers were divided into two groups: non-football players (20 each, 10 males and 10 females) and 60 non-athletes of various ages (10-20, 20-30, and 30-40) (10 participants from each gender for each group). Results: The height, weight and BMI are increased in sport male and female groups, The medial orbitofrontal, the pars orbitalis, the superior frontal and the frontal pole in the right frontal lobe in females in the sport group, the pars orbicularis and pars triangularis in the left frontal lobe is increased significantly in the sport group, The medial orbitofrontal and pars triangularis are increased significantly in the left frontal lobe in the male group aged 10-20 years, The caudal middle frontal, the medial orbitofrontal, the paracentral, the pars triangularis, the pars orbicularis and superior frontal gyrus are increased significantly in the female aged 10-20 years in the right frontal lobe while the lateral orbitofrontal and the frontal pole increased significantly in the female aged 20-30 years and medial orbitofrontal and paracentral in female aged 10-20 years in the left frontal lobe. Conclusion: age, gender and physical exercise can affect different parameters of the frontal lobe of the brain KEY WORDS: volumetric, frontal lobe, exercise, High-resolution MRI.

High Resolution Mri

Magnetic resonance imaging (MRI) has become established as an important imaging modality for the clinical management of disease. This is primarily due to the great tissue contrast inherent in magnetic resonance images of normal and diseased organs. Due to the wide availability of high field magnets and the ability to generate large and rapidly switched magnetic field gradients there is growing interest in applying high resolution MRI to obtain microscopic information. This symposium on MRI microscopy highlights new developments that are leading to increased resolution. The application of high resolution MRI to significant problems in developmental biology and cancer biology will illustrate the potential of these techniques.In combination with a growing interest in obtaining high resolution MRI there is also a growing interest in obtaining functional information from MRI. The great success of MRI in clinical applications is due to the inherent contrast obtained from different tissues leading to anatomical information.
