Rostral to midbrain are cerebral cortex, white matter, and basal ganglia {telencephalon}|. Cerebral cortex has frontal, parietal, temporal, occipital, insular, and limbic lobes.
evolution
In amphibians, dorsal telencephalon became dorsal cortex and hippocampus. Medial telencephalon became septum, which connects to hippocampus. Lateral telencephalon did nothing, because amphibians have no dorsal ventricular ridge. Ventral telencephalon became striatum, for muscle control.
In reptiles, dorsal telencephalon became dorsal cortex and hippocampus. Medial telencephalon became septum. Lateral telencephalon became dorsal ventricular ridge, for senses and/or emotions. Ventral telencephalon became striatum.
In birds, dorsal telencephalon became hyperstriatum with wulst. Medial telencephalon became septum. Lateral telencephalon became dorsal ventricular ridge. Ventral telencephalon became striatum.
In mammals, dorsal telencephalon became cerebrum, including neocortex and hippocampus. Medial telencephalon became septum. Lateral telencephalon became laterobasal amygdala for emotions. Ventral telencephalon became striatum.
