Your brain is the processor that allows your perception of the world. We’re in a constant cycle of figuring things out. Every moment, your mind is processing data. Taking in new information. Mapping out reality. Understanding what’s going on in the world.
Every day, in each moment, we consider whether or not its vital to update our internal map of reality. And it’s the largest part of the brain that’s doing most of this work.
Which Part Of The Brain Is The Largest Part And What Is Its Function?
The most advanced contraption in the known universe is found in the 3.3 pound blob of jello-like material swashing around in your head. And at 80% of your overall brain volume, your cerebrum is the largest part of this. So, it’s the cerebrum that is both the largest and smartest part of your superbrain.
At 85% of the entire brain’s weight, this supercomputer is an efficient network made mostly of grey matter.
The cerebrum is home to many of the 86 billion neurons found in the grey matter of our brains. Known to many as the “seat of consciousness,” it’s where your perception, memory and data from the senses come together to make sense of everything.
Structurally, the cerebrum, the biggest part of the forebrain, can be split into 2 hemispheres. And each of these 2 hemisphere’s are further divides into 4 lobes.
The four lobes of the brain are the frontal, parietal, occipital and temporal lobes:
1. Frontal Lobe
Responsible for: movement and speech.
Here’s the hub of your personality, planning and decision making.
You can find the frontal lobe at the front of the brain, and it’s the largest of all of the lobes. As well as attention, impulse control and problem solving, it handles memory, motor skills and speech.
Without it you’d have no inhibitions or moral compass.
2. Parietal Lobe
Responsible for: sensing, touch.
Positioned just behind the frontal lobe, the parietal lobe helps interpret sensory data from the other parts of the brain. Contained here is the somatosensory cortex, which processes touch and body sensations.
3. Occipital Lobe
Responsible for: visual processing.
This is your visual processing center. Located in the back of the brain, the occipital lobe is involved in reading, color recognition, and other visual information from the retina. Visual memory is also processed here.
4. Temporal Lobe
Responsible for: hearing, memory.
The temporal lobe handles visual and verbal memory as well as interpreting reactions and emotions. The temporal lobe allows you to recognize faces, process language and speech. It’s home to structures of the limbic system such as the amygdala, and hippocampus. These also organize impulses and aid in auditory perception.
What Is The Difference Between The Cerebrum And The Cerebral Cortex?
The outer crust of the cerebrum is the cerebral cortex.
It’s a 2-4mm layer of grey matter that holds 10% of all the neurons of your brain. Here, sensory and motor data is processed to enable our sense of consciousness. And at over 10 billion nerve cells, the peaks and valleys of the cerebral cortex are the processing powerhouse of your cerebrum.
What Is The Largest And Most Complex Part Of The Human Brain?
Your brain’s work is never complete. Each moment it’s processing data to make sense of your world. Within 2/10s of a second, your brain reacts. Each moment we receive data through our senses. And much of this data gets processed in the largest part of your brain, the cerebrum.
Knowing how to grow the powerhouse of your brain is a big responsibility. But through learning something new each day, your Superbrain grows itself.
As Jim Kwik, Author of Mindvalley’s Superbrain Program, explains, “Great things always begin from inside.”
And sometimes, it’s as simple as just taking the next step of your journey.
