Corpus Callosum - Coggle Diagram
Corpus Callosum
Function
connecting two cerebral hemispheres (hill, 2021
made of white matter and 200million heavily myelinated nerve fibers (Goldstein et al., 2020)
transfers information between hemispheres (Goldstein et al., 2020)
topographical organization in transferring visual, auditory, and somatosensory information in posterior regions, and higher cognition is processing anteriorly (Goldstein et al., 2020)
in maturation plays crucial role in refining motor movements and cognitive functions (Goldstein et al., 2020)

Development
Cerebral commissures connect areas of the cerebral hemispheres (Moore et al., 2020)
Initially the corpus callosum lies in the lamina terminalis (Moore et al., 2020)
as the cortex enlarges, it extends beyond the lamina terminalis (Moore et al., 2020)
Between 19-21 weeks is the maximum increase in thickness (Hill, 2021)
At birth the corpus callosum extends over the roof of the diencephalon (Moore et al., 2020)
74 days gestation callosal axons appear (Hill, 2021)
84 days- subdivisions of the genu and splenium can be identified (Hill, 2021)
115 days adult morphology seen (Hill, 2021)
