Introduction
The brain is a sensitive part of a human’s body; it is also the part that controls everything we do. According to (Carter, 2014) a brain is sensitive to different chemicals and can affect it negatively or positively. This is because it is a part of the nervous system that controls every part of our daily life. When eating a pizza the properties in the pizza itself interact with the brain, in lay mans terms is chemical dose from mouth to brain (Carter, 2014).
It affects the brains sensory nerves because there are many reactions before actually eating the Pizza. The smell of any type and the feeling in the mouth are the most crucial in making the experience pleasurable. In other words it is not necessarily due to energy homeostasis that we desire to eat (August, 1987).
The part that is involved with sensory and motor signal relay is called thalamus. In sense it is correct to indicate that most sensory processes such as eating involve thalamatic nucleus that receives sensory signal. It acts as a gateway that directs impulses to the cortex from the sub cortical nuclei. It does not play a major role in feeding as opposed to hypothalamus but it controls energy homeostasis. In pizza the fat in cheese and mushroom which contain fat actually helps gain more energy .Reason being the body burns curbs more quickly and this generates more energy (Carter, 2014).
The hypothalamus helps in regulating temperature, hunger, blood pressure, heart rate and thirst. It performs its function by navigating signals of the homeostatic mechanisms that it controls such as hunger and energy balance. As mentioned it helps our bodies maintain homeostasis especially when calories are low (Carter, 2014). This is why when an individual takes a bite of pizza it activates brain pleasure center that relays message to the entire body. The thing people understand as craving is actually a hunger hormone known as Ghrelin which increases lust before meals.
There is a nervous tissue located in the temporal lobe of the brain. It is responsible for the perception of emotions and acts as stimuli in survival. The activity that brings satisfaction to the brain on the different flavor of any pizza is formulated through the amygdala. It detects the flavor intensity of a particular food and acts as an emotional regulator especially cue on food. Through the connection from the hypothalamus and amygdala we essentially learn how to regulate food behavior. When an individual walks by a pizza outlet the cue for food intensifies. That is where the brain identifies intensity of flavor that determines the degree of hunger and desire. In order to control eating there is a median that is known as amygdalohypothalamic that controls.
The hippocampus acts a server for the brain as it stores memories of all past knowledge and experience. After eating a slice of Pizza the body feels relieved but the next day we desire some more. Thus the Hippocampus main role is to recall facts or events that the brain purposely wants to remember.
Conclusion
The brain requires all the above to process while eating a pizza .When consuming a pizza an individual salivates before even inserting the pizza in His or her mouth (Carter, 2014). The reason we enjoy foods with sprinkles, added ingredients and sauces is because they cover the taste buds causing us to salivate.
