**2.1 Analyzed areas**

Lateral geniculate body and prefrontal cortex: attraction for appearance. The appearance of food is more important than taste in many cases, even when food is prepared with the same ingredients and cooking methods. When we see something we shouldn't be eating, the brain sends an alarm. You can be fooled by stimuli of the smell of good food and the sound of frying, for example, which stimulate the production of ghrelin.

Accumbens Core: Food generates dopamines and serotonins and the tastier the better (our brain tends to prefer foods with more fat). It is related to pleasure.

Olfactory cortex: smell is one of the oldest senses and its stimulus is received in the olfactory bulb that directs the stimulus to the olfactory cortex, limbic system, motor cortex and others.

Visual cortex: related memory and visual processing.

Prefrontal cortex: related to planning complex behaviors and thoughts, expression of personality, decision making and modulation of social behavior.
