Is there a mapping of Socionic Types on hemisphere predominance?
SFs use their genitals, not their brains
Its simple, right=P left=J. Just because a person is J doesn't mean they don't view things holistic and creatively. Same thing vice versa about analysis and J. Every person has both Right and Left brain functions. INTjs for example have -Ti/+Te left brain +Ne/-Ni right brained.

And in MBTT writings, for example Lenore Thomson's, you will also see that they correlate P with the right hemisphere and J with the left hemisphere.We think that the top part of our picture correlates with the RIGHT brain hemisphere, and the bottom part – with the LEFT brain hemisphere. However, this hypothesis needs to be researched further.
It has also been suggested somewhere that (in MBTT terminology) Si, Te, Ni, and Fi are left brain, and that Fe, Se, Ne, and Ti are right brain. But in that context we must keep in mind that in MBTT Ti is seen as holistic and non-linear and as the dominant function of P types, that Ni is seen as the dominant of the INTJ "system builders" (which is the same type as the LII), and that Si is also a clearly J function that they use to explain the behaviours and attitudes of ESIs (ISFJs) and LSIs (ISTJs).
Rational behaviour and attitude in general is left brain, irrational behaviour and attitude is right brain -- that is the overall picture.
There is also a slight controversy about autism. Some people say that people with Asperger's Syndrome are strongly left brained, but that is probably not true. The behaviour I described earlier is, in its extreme form, most clearly expressed in autistic savants, like for example Kim Peek. Their extraordinary abilities in certain areas, like exceptional memory for details, etc., can be caused by a low-functioning left hemisphere that is compensated by a more developed right hemisphere. Some scientists believe that this could be one of the keys to understanding creativity, a phenomenon that is traditionally supposed to be linked to the right hemisphere.
The left hemisphere functions, in many ways, as a filter of information, and a perfect example of that phenomenon is Expat and other rational types, who according to Socionics naturallly filter information at an earlier stage in the information gathering process than irrational types do.
Rational (J) behaviour is judging behaviour, it means interpreting and filtering the information according to preestablished critera, whereas savant/autistic/Asperger behaviour means not interpreting, not filtering, not judging the information -- at least not until much later in the infomration gathering process. This could explain why people with Asperger/autism think in unusual ways, and why Asperger is linked to ingenuity. Einstein, Wittgenstein, Newton, Mozart, Michelangelo, da Vinci have all had clear autistic traits, and at least the first two definitely had Asperger. It could be the absence of an "interpreting filter" that explains their creativity. They are able to see the world in a more direct way than normal people, without prejudices, and therefore they are able to see what normal people will overlook.
The brain is a three dimensional structure. It's probable that when people talks about right and left brain they are really talking about the neocortex and limbic systems instead.
One thing that I find very curious about the transcription of the video is that it describes the right brain both in terms of Ne (holistic) and Si (sensorial). It could be that my theory that sensing and intuition are not different modes of thinking like socionics proposes, but rather extremes of the same scale more in line with MBTI theory.
It would be something like this:
Te: limbic - Fi: cortex
Fe: limbic - Ti: cortex
Ne: limbic - Se: cortex
Si: limbic - Ni: cortex
Te - Fe scale (limbic)
Ti - Fi scale (cortex)
Ne - Si scale (limbic)
Se - Ni scale (cortex)
Dominants are people who rely on a single layer. Balanced are those who rely on both layers.

Limbic dominants (caregivers):
