Is connected to the right by the corpus callosum

Answer

**Step-by-Step Solution:**

1. **Understanding the Corpus Callosum**: The corpus callosum is a significant structure in the brain made up of white matter. It consists of nerve fibers that facilitate communication between the left and right cerebral hemispheres.

2. **Location of the Corpus Callosum**: The corpus callosum is located deep within the brain. It lies beneath the cingulate gyrus and above the fornix, which are other structures in the brain.

3. **Function of the Corpus Callosum**: Its primary function is to connect the left and right hemispheres of the brain, allowing for the transfer of information between them. This connection is crucial for coordinating activities and processing information that involves both sides of the brain.

4. **Presence in Mammals**: The corpus callosum is specifically found in placental mammals, which distinguishes it from some other types of mammals that may not have this structure.

5. **Conclusion**: Therefore, the statement "is connected to the right by the corpus callosum" refers to the role of the corpus callosum in linking the right cerebral hemisphere to the left, enabling inter-hemispheric communication.
