From the described experiment it is clear that the mere act of eating, the food even not reaching the stomach, determines the stimulation of the gastric glands.

If we could look through the skull into the brain of a consciously thinking person, and if the place of optimal excitability were luminous, then we should see playing over the cerebral surface, a bright spot with fantastic, waving borders constantly fluctuating in size and form, surrounded by a darkness more or less deep, covering the rest of the hemisphere.
Interpretation
What this quote means
The quote imagines visualizing the active thoughts in a person's brain as a radiant spot amid darkness, emphasizing the complexity of thought processes.
In this quote, Ivan Pavlov vividly describes the essence of conscious thought by using the metaphor of light and darkness within the brain. He imagines that if we could observe the inner workings of a thinking mind, we would see a bright, dynamic area representing active, fluctuating thoughts, surrounded by the quieter, less active regions of the brain. This illustrates the intricacies of mental activity and the contrast between active contemplation and background mental processes.
