Verified step by step guidance

Step 1: Understand the anatomy of the brain's surface. The brain has various structures, including grooves and ridges, which are important for its function and organization.

Step 2: Define the key terms: A 'lobe' refers to a larger division of the brain, such as the frontal, parietal, temporal, or occipital lobes. A 'fissure' is a deep groove that separates large regions of the brain. A 'gyrus' is a ridge or fold on the brain's surface. A 'sulcus' is a shallow groove on the brain's surface.

Step 3: Compare the definitions to the question. The question specifically asks for the term that describes a shallow groove on the brain's surface.

Step 4: Eliminate incorrect options based on their definitions. A lobe is not a groove, a fissure is a deep groove, and a gyrus is a ridge. This leaves 'sulcus' as the correct term for a shallow groove.

Step 5: Confirm the answer by recalling that sulci (plural of sulcus) are commonly found between gyri on the brain's surface, helping to increase the brain's surface area and accommodate more neurons.
