Answer:
amygdala
Step-by-step explanation:
The amygdala is part of the so-called deep brain, in which basic emotions such as anger or fear prevail and also the survival instinct. Basic, no doubt, for the evolution of any kind. The amygdala, this almond-shaped structure, belongs to all vertebrates and is located deep within the temporal lobes, forming part of the limbic system and processing everything related to our emotional reactions.
The amygdala is the part of the brain with dense connections to a variety of sensory areas; is critical to classical conditioning and to attaching emotional value to memory
It is the amygdala that warns us that darkness is a risk and that this approaching person is also a risk. Moreover, it creates new learning by deducing from fear that the next day we will not park the car on this street.
