Conclusions

  1. 1.

    For the first time, using the technique of thermovision and digital treatment of images through the unopened skull, we have investigated the background thermal fields and reactions to light in the cerebral cortex of rats at different times during the taking of the neurotransplant of visual cortex, amygdalum, or hippocampus into the visual cortex.

  2. 2.

    We have observed the appearance after the operation of significant thermal asymmetries in the cortex, which at different times (2-15 days) are dynamic but become stabilized after 5–5.5 months.

  3. 3.

    At later dates the region of the successfully taken transplant is indistinguishable against the background from the surrounding brain as regards temperature, but on resorption of the transplant and on pseudotransplantation (introduction of a physiological solution into the cortex) this region is cooled.

  4. 4.

    A thermal reaction differing from the normal develops in response to light stimulation in the region of the transplant, at early periods it being apparently associated with inflow of heat from the surrounding sections of the cortex.

  5. 5.

    The thermovision control of the taking and development of neurotransplants in the cerebral cortex is promising since it is highly sensitive, possesses good time and spatial resolution, does not involve contact, and is noninvasive.
