Longitudinal bands of nervous tissue which connects the cerebral hemispheres with the pons are

Cerebral peduncles or crura cerebri connect the forebrain with the hind brain.

The cerebral peduncles are the two stalks that attach the cerebrum to the brainstem.[1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) nerve tracts that run to and from the cerebrum from the pons.

The cerebral peduncles are located on either side of the midbrain and are the front most part of the midbrain, and act as the connectors between the rest of the midbrain and the thalamic nuclei and the cerebrum.
