Researchers report successful transplantation of human brains into baby rats
| To test wether or not the brain tissue modulated rat behaviour, we placed animals into a behavioural testing chamber and applied randomly interleaved presentations of blue and red laser stimulations. Animals received a water reward if they licked during the blue light stimulation, but not if they licked during the red light stimulation.
| On the first day of training, animals showed no difference in their licking behaviour during either blue or red light stimulation. However, on day 15, animals who recieved the transplant showed increased licking during blue light stimulation compared with red light stimulation. These changes in licking behaviour were not observed in control animals. These data suggest that transplanted cells can activate rat neurons to drive reward-seeking behaviours.
| To explore what rat neural circuits might be engaged to drive these changes in behaviour, we optogenetically activated the transplanted tissue in trained animals which revealed expression of the activity-dependent protein FOS in several brain regions implicated in motivated behaviours, including the medial prefrontal cortex, the mediodorsal thalamus and the periaqueductal grey.

| There is no indication that the headline was slightly altered for clickbait purposes nor is there any indication that OP is a rat with a giant-ass human brain transplanted in his head. Any and all similar assumptions is fake news anti-kibology propaganda.

| The transplanted brain tissue appeared highly functional, to mature and to integrate with the rest of the rat brain by making functional connections onto rat neurons and modulating behaviour.
