Parts of the amygdala

In this BIOLOGY video we will explain "Parts of the amygdala".

Parts of the amygdala. A region that is super important to generate intense emotional responses and that much has been studied in studies of fear conditioning, responses to stress... since it is a region that; When activated, it gives an emotional meaning to that situation we are experiencing and this emotional response often has to do with afraid. We can literally induce an aggressive or defensive response (classic response to fear), artificially stimulating the amygdala. First of all, when we say amygdala, we are talking about a lot of things. We wanted to highlight the nuclei of the amygdala and... before entering them, we are going to comment to what extent this structure is connected with so many other structures of the nervous system and as something, as immediate or little premeditated as it is to feel fear, actually has a lot to do with; how we perceive, with what information is coming from other regions. That is, I would like to relate this response that occurs through the amygdala through the

afferences and deferences receiving. References: information arrivals. Information comes to the amygdala from the brain stem. That is, elementary information about; my breathing rate, heart rate, blood glucose levels... that information can go through the thalamus and then go to the amygdala (because the thalamus is mainly responsible for being a relay place for sensory information) or directly comes from the trunk. You can get there in both ways. There are these two information arrivals.
