The Human Brain : The Three Parts Of The Human Brain

First of all, I thought it was very interesting to learn that there are 3 distinct parts of the human brain that have evolved over time. These three anatomical puzzle pieces each serve various purposes ranging in complexity. The brainstem is the oldest piece of our brain and it takes care of many functional aspects of our daily lives such as breathing, sleeping, and regulating heart beats. On top of our brain stem is our mammalian brain which all mammals have. It gives us all the basic instincts that we need for survival in the wild such as our sex drives, flee or fight instincts, and knowledge of when to eat and how to acquire food. Also apart of our mammalian brains is our amygdala which is what makes us to experience emotions, our hippocampus which allows us to process short-term memories into long-term memories, and our thalamus which is in charge of processing everything that can sense in our environment. As complex as our mammalian brain sounds, it is no match for our human brain that's folded atop of it called the cortex. The cortex is a complex layer of tissue that is in constant communication with other areas of the brain and body. Different sections of the cortex are responsible for different activities such as vision, speech, and memory. The cortex is the most sophisticated layer in our brain and is what separates us from other mammals. Only a few months after they are born, most animals are considered adults. Humans are not like this. Once humans are born, we
