The rhinencephalon, associated with the sense of smell, is the oldest part of the telencephalon. The embryonic forebrain becomes subdivided into the telencephalon anteriorly and the diencephalon posteriorly. The rock-dwelling species possess larger cerebra, or telencephala, perhaps to aid in navigating their complex environments. The brain & nervous system abducens nerve abducent nerve accessory nerve alexithymia allism glossopharyngeal nerve grey matter hemispheric hemispherical hindbrain neurofibrillary neurogenic neurogenically neuroglia neuroglial reinnervation reticular formation rhinencephalon rhombencephalon right brain Examples of telencephalontelencephalon The thalamus is the gateway for sensory and motor traffic into and out of the telencephalon.

There have been important disagreements as to which components of the non-mammalian telencephalon can be compared to the isocortex. Some data on the behavioral effects of lesions of the telencephalon in turtles may bear on the authors' hypotheses. The majority of larvae were recorded from the telencephalon and the cerebellum. The hypothesis is based on the overlap (mixture) of two neurogenetic territories during the early stages of anterior telencephalon development. Within the telencephalon, over 60% of the larvae were located in the corpus callosum. In the embryonic mammalian telencephalon, distinct markers for pallial and subpallial regions have been detected. Unfortunately, other sensory connections of the thalamus, including projections to the telencephalon, have not been investigated experimentally. They concluded that these cells modulate the visual information from the retina to the telencephalon during eye movements. These examples are from corpora and from sources on the web.
