The lateral ventricles communicate with the third ventricle through the Foramen of Monro, also known as the interventricular foramen. This opening serves as a vital conduit allowing the flow of cerebrospinal fluid (CSF) between the two lateral ventricles and the third ventricle. Each of the lateral ventricles has one Foramen of Monro, facilitating the equal and regulated exchange of CSF, which is crucial for maintaining intracranial pressure and overall brain health.

In contrast, the other options refer to different anatomical structures involved in the brain's ventricular system. The Aqueduct of Sylvius connects the third ventricle to the fourth ventricle, while the Foramen of Luschka represents exits of CSF from the fourth ventricle into the subarachnoid space. The Central Canal is a narrow channel that runs down the spinal cord and does not play a role in the communication between the lateral and third ventricles. Thus, the Foramen of Monro stands out as the correct answer for this specific communication pathway.
