Is it scientifically backed that sensory signals always go through limbic/emotional brain system? From the book Emotional Intelligence 2.0 by Travis Bradberry &amp; Jean Greaves:

The daily challenge of dealing effectively with emotions
is critical to the human condition because our brains are
hard- wired to give emotions the upper hand. Here’s how it
works: everything you see, smell, hear, taste and touch travels through your body in the form of electric signals. These
signals pass from cell to cell until they reach their ultimate
destination, your brain. They enter your brain at the base
near the spinal cord, but must travel to your frontal lobe
(behind your forehead) before reaching the place where rational, logical thinking takes place. The trouble is, they pass
through your limbic system along the way—the place where
emotions are produced. This journey ensures you experience
things emotionally before your reason can kick into gear.


Is the presented as fact that senses such as seeing/sight go through Emotional/Limbic system prior to reaching Rational neo-cortex layer. Is this the current scientific stance?
While it is true that emotional life is largely housed in the limbic system, the model seems to be over-simplistic to me. There are more complex emotions that are housed in the neocortex, not just the limbic system*. However, it can still be useful to teach for layman? Similarly to the triune brain model.
For a good introductory video course on emotion, see Human Emotion, host by June Gruber, prof in Yale.
* I believe I have this claim when watching this course, but I cannot find the particular video that make that statement.
