Given this complexity, it shouldn’t be surprising that there are several ways to separate the portions of the brain. Brain parts can be separated on the basis of what they look like to the naked eye, under a microscope, or by what certain brain parts do. The brain and spinal cord make up the nerve system and all the nerves found in our body make up the peripheral nervous system.
Cortex can be divided into four main lobes
Whenever you see an image of the brain you probably think of a wrinkled gray blob. Well, the wrinkles are called cortex and it’s where the majority of brain cells or neurons reside. The cortex can be divided into four main lobes. The frontal lobe, where you do the heavy thinking, contemplating and planning your actions, temporal cortex, where it processes sounds and form memories, occipital cortex, where you process all the things which you see, and parietal cortex, where it integrates or makes sense of all of the different bits of info which are bombarding your brain. The Hindbrain – Having evolved hundreds of millions of years ago, the Hindbrain or the Reptilian Brain is the oldest part of the brain.
It is a piece of brain anatomy
As you may guess from it is a name, it is a piece of brain anatomy that we share with reptiles and is the most primitive. Similarly, it is in charge of our primary instincts and most basic functions. Things such as the instincts of survival, dominance, mating and the basic functions of respiration, heartbeat all come from this area of the brain. Based on the Hindbrain are The Spinal Cord – This is the information superhighway of the body. Also acts as a relay station for nerve signals going to\/from the brain – The Pons – Has roles in your level of excitement or consciousness and sleep.
Relays sensory information to\/from the brain. In addition, involved with controlling autonomic body functions. The Cerebellum – Mainly deals with movement. In addition, involved with learning movement. The Limbic System – The Limbic System sometimes called the emotional brain or Old Mammalian Brain is the next part of the brain to have evolved in the more primitive mammals about 150 million years ago. This is where our emotions reside, where memory begins and where both of these functions combine together to mark behaviors with negative or positive feelings. Based in the Limbic System is The Amygdala – It is name is Latin for almond which relates to its shape. Like the Memory in your computer, it processes and stores new and temporary memory for long term storage.
