An anatomical and volumetric study on brain ventricles in sheep using different techniques

Area of Science:

• Veterinary Anatomy
• Neuroscience
• Comparative Morphology

Background:

• The ventricular system of the brain is crucial for cerebrospinal fluid circulation and brain homeostasis.
• Understanding species-specific neuroanatomy is vital for comparative studies and veterinary medicine.

Purpose of the Study:

• To conduct a detailed morphological and morphometric investigation of the brain's ventricular system in Akkaraman sheep.
• To establish breed-specific brain indices and morphometric data for Akkaraman sheep.

Main Methods:

• Utilized latex and acrylic injections with dissection and corrosion casting.
• Employed magnetic resonance imaging (MRI) for non-invasive visualization.
• Applied digital calipers, Archimedes' principle, Cavalieri's principle, and ITK-SNAP software for precise measurements.

Main Results:

• Detailed measurements of brain weight, volume, and dimensions were recorded.
• Identified a ventricle-like cavity in the olfactory bulb and a large cavity within the septum pellucidum.
• Quantified the total ventricular volume using multiple methods, yielding consistent results.

Conclusions:

• The study provides comprehensive morphometric data on the Akkaraman sheep brain's ventricular system.
• This research contributes valuable species and breed-specific anatomical information.
• Findings can serve as a reference for future neuroanatomical and comparative studies in sheep.
