The word "sulcus occipitotemporalis" refers to a groove in the brain that separates the occipital and temporal lobes. Its spelling may seem daunting, but the International Phonetic Alphabet (IPA) can help break it down. "Sulcus" is pronounced /ˈsʌlkəs/, "occipitotemporalis" is pronounced /ˌɒksɪpɪtəʊˌtɛmpəˈrɑːlɪs/. The "s" sound in "sulcus" is followed by a "u" sound, making "sul" pronounced as "sull." Additionally, "occipital" and "temporal" are pronounced as written. Mastering the IPA can make seemingly difficult words much more approachable.
The sulcus occipitotemporalis, also known as the occipitotemporal sulcus or the lateral occipitotemporal sulcus, is a major anatomical structure located in the human brain. It is a prominent groove that runs along the lateral surface of the brain, serving as a landmark for the separation of two important lobes, namely the occipital lobe and the temporal lobe.
This sulcus can be observed on the outer surface of the brain, starting from the posterior region in the occipital lobe and extending anteriorly towards the temporal lobe. It marks the boundary between these two lobes, and its depth and folding pattern can differ between individuals but usually shows a consistent location.
The sulcus occipitotemporalis serves as an important functional landmark in the brain, as it demarcates cortical regions that are involved in visual perception and object recognition. Specifically, the ventral fusiform gyrus – a key area associated with processing visual stimuli, faces, and word recognition – is typically located within this sulcus. It is involved in the neural mechanisms implicated in the perception and recognition of highly complex visual information, making it vital for various cognitive processes.
In conclusion, the sulcus occipitotemporalis is a significant groove in the human brain that separates the occipital and temporal lobes. It helps identify the boundary between these two regions and is important for understanding the neural processes involved in visual perception and object recognition.

The term "sulcus occipitotemporalis" originates from Latin.
- "Sulcus" comes from the Latin word "sulcus", which means "a furrow" or "a groove". It is commonly used in anatomy to refer to a depression or groove in an organ or tissue.
- "Occipito-" refers to the occipital bone, which is the bone located at the back and base of the skull. It gets its name from the Latin word "occiput", meaning "the back of the head".
- "-temporalis" is derived from the Latin word "temporalis", which means "pertaining to the temples" or "relating to the temples". It refers to the area of the skull located on the sides of the head, near the temples.
