From the Research
The collateral sulcus is a crucial anatomical landmark located on the inferior surface of the temporal lobe, playing a significant role in brain organization and cognitive functions, as evident from the most recent study in 2018 1. The collateral sulcus is a prominent groove that runs parallel to the hippocampal sulcus, separating the parahippocampal gyrus medially from the fusiform gyrus laterally.
- It extends anteriorly from the occipital lobe toward the temporal pole, typically measuring about 7-8 cm in length.
- The depth and exact configuration of the collateral sulcus can vary between individuals, but it remains a consistent feature in neuroanatomy.
- The sulcus contains cerebrospinal fluid and small blood vessels that supply the surrounding cortical regions.
- Understanding the location of the collateral sulcus is important for neurosurgeons when planning temporal lobe procedures and for neurologists when interpreting brain imaging studies, as highlighted in the study published in 2018 1. Key points to consider:
- The collateral sulcus is divided into three segments: the rhinal sulcus, the collateral sulcus proper, and the occipital extent of the collateral sulcus, as described in the study published in 2012 2.
- The topographic anatomy of the collateral sulcus with its surrounding structures is detailed in the study published in 2018 1, which provides valuable information for neurosurgeons and neurologists.
- The study published in 2014 3 also highlights the importance of understanding the sulcal and gyral anatomy of the basal occipital-temporal lobe, including the collateral sulcus, for accurate interpretation of radiological and intraoperative findings.
