Limbic Lobe

As I have already talked about the basics parts of our brain, this part named Limbic Lobe is located inside the Cerebrum.

The upper diagram the shows the Limbic Lobe also known as Limbic System. In this article, I will talk about several functions of their parts.

The first part I would like to talk about is Amygdala. The Amygdala is a part in our brain that is mostly involved in processing emotions. Mostly the emotions of fear that alert us. For Example, An experiment was performed on a mouse,in that experiment, the researchers surgically stopped Amygdala from working. The researchers then putted the mouse in the cage of  a hungry cat, and they found that the mouse got into the hands of the cat very easily and the mouse was still not afraid, that is a sign that the Amygdala plays an important role in processing the emotion of fear.

Now let's talk about Hippocampus, Hippocampus is a part in our brain that is involved in making memory. I have already talked about it in my previous post and you can read that post for getting information about it.

Next I will talk about The Thalamas. The Thalamas is like a gateway for the Cortex, very information that wants to visit the Cortex must first pass through here to be able to go to the Cortex. The Cortex here might even cancel the information and it might not allow the information to reach the Cortex. For Example, when you are in your school and your teacher teaches you a very important lesson, you might not hear the tick tick sound of the clock, this is because the Thalamas after sometime does not allow the sound to reach the Cortex because the Cortex is already involved in understanding the lesson.

The Cingulate Gyrus is the part of our brain that processes the autonomic nervous system that is this part of our brain adjusts the Blood Pressure, Pupil Size, Heart Rate and other things which are not in our control.

Hypothalamas and Pituitary Gland.
The Hypothalamas is located just below the Thalamas and is mostly involved in maintaining the internal environment of our body by increasing or decreasing the feeling of Hunger, Thirst etc. It also affects the rate of our growth by getting a control over the Pituitary Gland. The Pituitary Gland secretes the Growth Hormone and it only sends the Growth Hormone when it gets the signal from Hypothalamas.

Next, I would like to talk about Corpus Callosum, This part of our brain helps both the hemispheres of our brain to contact with each other. There are two hemispheres of our brain, they are left and right hemisphere and this both contact each other with the help of Corpus Callosum.

The Limbic Lobe can be said as the heart of our brain. We cannot have emotions without it.

This is all I wanted to include in this article.

Thanks for reading.
