Resumen
Objective: Callosal structural and functional alterations have been demonstrated in a range of neuropsychiatric illnesses, including bipolar disorder, but no study has examined regional callosal thickness in this phenotype. The aim of the present study was therefore to examine callosal size and shape in a well-defined group of bipolar affective disorder patients and controls. Methods: The participants included 24 patients with DSM-IV bipolar I disorder and 24 matched healthy controls. The corpus callosum was extracted from mid-callosal images from T1-weighted magnetic resonance imaging scans o

Resumen
Shape analysis provides a unique insight into biological processes. This paper evaluates the properties, performance, and utility of elliptical Fourier (eFourier) analysis to operationalise global shape, focussing on the human corpus callosum. 8000 simulated corpus callosum contours were generated, systematically varying in terms of global shape (midbody arch, splenium size), local complexity (surface smoothness), and nonshape characteristics (e.g., rotation). 2088 real corpus callosum contours were manually traced from the PATH study. Performance of eFourier was benchmarked in terms of its ca

Resumen
Fitch & Denenberg have shown that manipulations of ovarian and testicular hormones early in development can influence the adult size of the corpus callosum in the rat. The human corpus callosum is highly variable in size and shape, but data are only now beginning to emerge on whether sex steroids influence callosal differentiation in humans. I describe recent data from our own laboratory and suggest avenues for future research.

The corpus callosum is the largest white matter structure in the brain, which connects the two cerebral hemispheres and facilitates the inter-hemispheric communication. Abnormal anatomy of corpus callosum has been revealed for various brain related diseases. Being an important biomarker, Magnetic Resonance Imaging of the brain followed by corpus callosum segmentation and feature extraction has found to be important for the diagnosis of many neurological diseases.

Resumen
The importance of accurate diagnostics of autism that severely affects personal behavior and communication skills cannot be overstated. Neuropathological studies have revealed an abnormal anatomy of the Corpus Callosum (CC) in autistic brains. This chapter proposes a new approach to quantitative analyses of three-dimensional (3D) Magnetic Resonance Images (MRI) of the brain that ensures a more accurate quantification of the anatomical differences between the CC of autistic and normal subjects. It consists of three main processing steps: (1) segmenting the CC from a given 3D MRI using the learn

Resumen
Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that is characterized by abnormalities in behavior and higher cognitive functions. The corpus callosum (CC) is the largest fiber bundle that connects the left and the right cerebral hemispheres of the human brain. Several studies have revealed an abnormal anatomy of the CC in the brains of autistic individuals that associates this neurodevelopmental condition with impaired communication between the hemispheres. In this chapter, we develop a framework to analyze the CC of autistic individuals in order to provide a diagnosti

This chapter examines facial emotion recognition, a vital skill for social interaction and emotional development, from evolutionary, developmental, and neurological perspectives. It explores how children's ability to recognize emotions develops through social experiences, brain maturation, and lateralization. Key milestones, such as the shift from featural to holistic facial processing and sensitivity to emotional intensity, are discussed alongside insights into the right hemisphere's dominance in emotion recognition. The chapter also highlights sex differences, the role of the corpus callosum
