The essential error of the Cannon-Bard theory was to consider the existence of an initial "center" for emotions (the thalamus). Soon enough, though, in 1937, the neuroanatomist James Papez would demonstrate that emotion is not a function of any specific brain center but of a circuit that involves four basic structures, interconnected through several nervous bundles : the hypothalamus with its mamillary bodies, the anterior thalamic nucleus, the cingulate gyrus and the hippocampus. This circuit (Papez circuit), acting in an harmonic fashion, is responsible for the central functions of emotion (affect), as well as for its peripheral expressions (symptoms).
So, there we go. The hypothalamus alone IS NOT responsible for HUMAN emotions.
With regard to whether a reptile has little or no hypothalamus I have yet to discover, but this document shows that emotions IN HUMANS are not just processed by the hypothalamus.
Found what I was looking for. At long last.
Yes, you are correct that it is a scientific fact that reptiles cannot "love" their owner...
Although some signs of affection can be perceived in birds, the limbic system only began to evolve, in fact, after the first mammals, being practically non-existent in reptiles, amphibians and all other preceding species.
My input will be continued in the next post....
