When a person falls in love, their brain experiences something similar to what occurs when gambling or consuming psychoactive drugs.
As the Spanish Neurology Society indicates, the neural processes that occur in the brain are what cause this feeling.
Advances in science and technology help determine the function of the brain circuits, neural structures and neurotransmitters that make people fall in love. As the Spanish Neurology Society explains, “When you fall in love, the different parts of the brain such as the hypothalamus, the prefrontal cortex, the amygdala, the nucleus accumbens (a group of neurons in the brain stem) and the ventral tegmental area play a big role.”
This is why feeling in-love causes neuronal changes in the areas of the brain related to perception, which explains why people who are in love see their partner as more unique than others.
