Justo Gonzalo RodrĂguez-Leal (March 2, 1910 – September 28, 1986) was a Spanish neuroscientist, who described and interpreted what he called "central syndrome of the cortex" which is a multisensory disorder with bilateral symmetry, due to a unilateral parieto-occipital cortical lesion.
In relation to this syndrome, the author described, among other disorders, the inverted perception disorder (visual, tactile and auditive) and the multisensory and motor facilitation.
This phenomenon consists on the improvement of the perception of a given stimulus by the presence of another different stimulus of the same or another sensory system (crossmodal), and particularly by means of muscular activity or effort.
He interpreted this syndrome by developing a model of brain dynamics based on neurophysiological studies of brain injury cases and biological principles of growth.The model emphasizes the functional unity of the cortex and offers a dynamic solution for the functional specializations of the brain by means of functional gradients through the cortex, and scaling laws.
He received awards from the Spanish National Research Council (Consejo Superior de Investigaciones CientĂficas) (1941), the Spanish Royal Academy of Medicine (Real Academia de Medicina) (1950), and the Spanish Society of Psychology (Sociedad Española de PsicologĂa) (1958).
