Summary
# High-Resolution Brain Mapping in Horses: Setting a New Standard for Neuroimaging Schmidt and colleagues have created the most detailed anatomical reference atlas of the equine brain to date, using 3Tesla MRI to acquire T2-weighted images at exceptionally fine 0.25 mm resolution in sagittal, dorsal and transverse planes, complemented by 3D reconstructions and correlated histological sections. This work addresses a significant gap in equine neuroanatomy, as previous imaging references have lacked the resolution necessary for detailed structural analysis or clinical diagnostic work. The resulting atlas will substantially improve veterinary practitioners' ability to interpret MRI findings in cases of neurological disease, head trauma or suspected intracranial pathology, whilst providing researchers with a robust foundation for future studies investigating in vivo brain structure and function in horses. For equine veterinarians with access to high-field MRI facilities, these reference images offer an essential tool for identifying anatomical variants, detecting lesions, and communicating imaging findings with greater precision. Beyond clinical application, this atlas creates possibilities for investigating breed differences, age-related changes and the neuroanatomical basis of behaviour and performance—questions of genuine interest to the broader equine professional community.

Practical Takeaways
- •Veterinarians can now reference detailed high-resolution equine brain imaging anatomy when interpreting clinical MRI scans for neurological cases
- •This atlas provides the anatomical foundation for identifying abnormal brain structures or lesions in living horses without needing to extrapolate from human/other species data
- •Future clinical applications will benefit from having validated equine-specific neuroanatomical reference, improving diagnostic accuracy for central nervous system conditions
Key Findings
- •High-field 3Tesla MRI with 0.25 mm resolution successfully generated detailed sagittal, dorsal, and transverse T2-weighted images of equine brain anatomy
- •3D reconstructed models of external brain morphology created from MRI data correlated well with histological validation
- •Detailed neuroanatomical atlas established as reference tool for in vivo MR image interpretation in horses
