In 1840 Baillarger was the first physician to discover that the [[cerebral cortex]] was divided into six layers of alternate white and grey laminae. His name is associated with the inner and outer [[Band of Baillarger|bands of Baillarger]], which are two layers of white fibers of the [[cerebral cortex]].

In the field of psychiatry, Baillarger did research on the involuntary nature of [[hallucinations]] and the dynamics of the [[hypnagogic state]] (the intermediary stage between sleep and wakefulness). In 1854 he provided a description of a [[bipolar disorder]] that he referred to as ''folie à double forme'' (dual-form insanity).
