Morphometric comparison of the human corpus callosum in professional musicians and non-musicians by using in vivo magnetic resonance imaging.

Magnetic Resonance Imaging-Based Morphometric Assessment of Sexual Dimorphism of Corpus Callosum

Introduction: Interhemispheric transmission of signal is done by corpus callosum (CC) as the largest fiber tract in brain. CC comprised 5 segments of rostrum, genu, body, isthmus, and splenium. Contradictory reports exist about sexual dimorphism of CC. We designed this study to assess probable sexual differences of CC and its different parts in men and women. Methods: We analyzed magnetic reso...

Morphometry of the corpus callosum: comparing male orchestral musicians and non-musicians

Can Musical Training Influence Brain Connectivity? Evidence from Diffusion Tensor MRI

In recent years, musicians have been increasingly recruited to investigate grey and white matter neuroplasticity induced by skill acquisition. The development of Diffusion Tensor Magnetic Resonance Imaging (DT-MRI) has allowed more detailed investigation of white matter connections within the brain, addressing questions about the effect of musical training on connectivity between specific brain...

Instrument specific use-dependent plasticity shapes the anatomical properties of the corpus callosum: a comparison between musicians and non-musicians

Long-term musical expertise has been shown to be associated with a number of functional and structural brain changes, making it an attractive model for investigating use-dependent plasticity in humans. Physiological interhemispheric inhibition (IHI) as examined by transcranial magnetic stimulation has been shown to be correlated with anatomical properties of the corpus callosum as indexed by fr...

Sexual Dimorphism and Age-Related Variations of Corpus Callosum Using Magnetic Resonance Imaging

Introduction: Despite technological advances and numerous published investigations, sexual dimorphism of Corpus Callosum (CC) remains a matter of ongoing controversy. In the present study on neurologically healthy Iranian adults, we investigated the possible gender- and age-related variations in anthropometric callosal measurements.  Methods: Our sample comprised 35 male and 35 female sub...
