You suffer from AGENESIS OF THE CORPUS CALLOSUM (ACC)
ACC is a congenital abnormality in which there is a partial or complete absence of the corpus callosum

One estimate comes from a survey of over 7000 MRI brain scans. Five cases of partial or complete agenesis were detected (0.069%).7 There was a 2:1 male to female ratio of adult cases in one survey and a 3:2 ratio in the children

The corpus callosum is the main transverse tract of fibers that connects the two cerebral hemispheres. The primary function of the corpus callosum is to integrate motor, sensory, and cognitive performances between then two hemispheres of the brain. The anterior portion of the corpus callosum is the genu, which curves ventrally and forms the rostrum. Continuing posteriorly the callosum becomes the body and end with the enlarged splenium. Once formed, the callosum thickens with increasing myelination, except during a period of axonal elimination near birth. Postnatally the corpus callosum undergoes a burst of growth during the first four years of life

The first symptoms of ACC are usually seizures, which may be followed by feeding problems and delays in holding the head erect, sitting, standing, and walking. The seizures may be caused by a very common disorder called infantile spasms, which is associated with ACC. There may be impairments in mental and physical development, hand-eye coordination, and visual and auditory memory. Hydrocephaly may also occur. In mild cases, symptoms such as seizures, repetitive speech, and/or headaches may not appear for years. Female children may also have a specific syndrome, Aicardi's syndrome, in addition to ACC and infantile spasms, in which there is severe mental retardation and chorioretinal lacunae (a space filled with calcified tissue). ACC may occur as an isolated condition or in combination with other cerebral anomalies including Arnold-Chiari malformation and Dandy-Walker syndrome, Andermann syndrome (with progressive neuropathy), schizencephaly, holoprosencephaly, and migrational anomalies. ACC is also associated with several chromosomal anomalies, including trisomy 13 and 18. There are non-nervous system malformations that may occur both with and without chromosomal aberrations such as midline facial defects

Treatment usually involves management of symptoms such as hydrocephaly and seizures. EI services may focus on oral motor problems, mobility training, and strengthening

Split-brain people can point to objects with their left hand (but not with their right hand) if visual information is presented from the left visual field to their right hemisphere. Information presented in the right visual field (thus going to the left hemisphere) allows patients to name or describe what they see.

The two hemispheres of a split-brain person can process information independently of each other. However, the brain eventually learns to use smaller connections between the left and right hemispheres to avoid conflicts between them.

What did your MD say? I think that is impossible because that is how your right and left brain talk to each other! Like, how are you functioning. Maybe you should request another test. It sounds like those machines were malfunctioning or maybe you misunderstood what the doc said.
