Which Side of the Brain Controls Memory?

The brain is one of the most complex organs. It is the main command center of the body, regulating how the rest of the body’s components function. It is the seat of information, interpreting the data obtained by your five basic senses. It also plays a key role in emotions and storage and retrieval of memories.

This organ is about 15 centimeters long and weighs around 3 pounds. However, it is made up of billions of nerve cells that communicate regularly to facilitate the brain’s functions. Overall, though, the brain has three major parts. These are the cerebellum, brainstem, and the cerebrum.

Cerebrum, Cortex, and Memories.

Of the three, the biggest is the cerebrum, where more than 65 percent of the nerve cells in the brain could be found. It is also responsible for a lot of functions from speech to mathematical analysis.

Serving as a cover for the cerebrum is the cortex, which is composed of 6 distinctive layers. The outermost surface looks like gray in color, and thus, it is commonly referred to as the gray matter. The cortex is composed of four lobes that traverse both hemispheres. These are occipital, parietal, temporal, and frontal.

Each of these lobes governs specific functions. For example, judgment, problem-solving, and the act of speaking occur in the frontal lobe, but it’s the parietal lobe that interprets language. However, all of them help create and retain memory.

The frontal lobe, which is at the front of both hemispheres and is above the temporal lobe, assists in processing short-term memories. It also stores non-task-based long-term memories. The temporal lobe, meanwhile, is the one responsible for processing data from your senses. As such, it is connected to the creation of long-term memory.

The inner part of it is called the medial and is related to the formation and retention of episodic memory. Within the medial is the hippocampus, which then converts short-term to long-term memory.
