The document provides an overview of the forebrain, highlighting its critical role as the processing center for perception, memory, and sensory data. It explains the forebrain's anatomy, including its main parts—the telencephalon and diencephalon—and their functions, such as regulating motor functions and managing hormonal responses. Additionally, it contrasts the roles of the forebrain, midbrain, and hindbrain to illustrate the evolutionary development and complexity of brain functions.

1. Superbrain: Everything You Need To
Know About Your Forebrain
Your brain is the most complex technology anywhere in the world. It’s made up of three major
parts: the forebrain, midbrain and hindbrain. These divisions allows us simplify and understand
the functions of the brain.
We’re going to take a closer look at the forebrain: the powerhouse supercomputer of the brain.
What Is The Function Of The Forebrain?
Each moment, your brain is processing data to make sense of your world. It takes just 2/10s of a
second for your brain to react.
As the the hindbrain and midbrain take care of our many subconscious functions, it frees the
forebrain for higher level processing. In fact, your primary forebrain function is to process
perception, memory and data from the senses. And it’s here that we make sense of everything.

2. The core of the forebrain is the cerebrum and cerebral cortex: the brain’s true powerhouses. The
cerebrum and cerebral cortex are the largest part of the brain. A complex web of grey matter that
makes up 85% of your brain’s weight. And within are housed 86 billion neurons which form
what many refer to as the “seat of consciousness.”
Next, let’s compare the functions of the hindbrain, midbrain and forebrain, starting from the
most primitive to most advanced.
What Is The Function Of The Forebrain, Midbrain And
Hindbrain?
During our lifetimes, our brains change radically. When you were just a baby, your brain grew.
First you had a spinal chord, then a hindbrain. Next, your midbrain formed. Finally, your
forebrain developed.
This is the same order the brain formed over millions of years of evolution. Our brains evolved
outwards from the spinal chord.
And this actually leaves us clues on the different functions of each of the part of the brain.
So, let’s see what’s going on under the hood:
Hindbrain
Getting its name for the Latin word for ‘bridge’, your hindbrain connects the spine to the higher
brain.
The hindbrain function is primarily a coordination hub sending and receiving signals between
the spine and brain. It helps handle more basic functions like facial movement, processing
sound, maintaining balance, speech and chewing.
Also located here is the medulla oblongata, which is the control center for the heart and lungs.
And it’s responsible for functions such as heart rate, blood pressure, breathing, swallowing and
sneezing.

3. Midbrain
Also known as mesencephalon, your midbrain connects to both the forebrain and hindbrain.
Together with the hindbrain, it forms the brainstem.
This is the part of your brain which connects to the spinal cord directly. Thus,
the primary midbrain function is to serve as your physical connection between the brain
and the rest of your body.
It controls movement and also processes vision and speech. Eye movement is handled here too.
And it also plays a role in motor and sensory functions like our body sensations and reflexes.
Forebrain
Sitting on top of the rest of the brain, your forebrain is the largest part of your brain. It takes
up 2/3 of your brain and comes in at roughly 1 pound in weight.
It’s also the most advanced part of your brain, handling executive higher functions such as
thinking, perceiving and language. It also helps in controlling motor functions and relaying
sensory data.
What Is Included In The Forebrain?

4. Now lets go further down the rabbit hole, and talk about the structure of the most advanced part
of your brain. The forebrain sits on and covers much of brain’s other structures. It has two
sections, known as the telencephalon and the diencephalon.
Telencephalon
The telencephalon contains the cerebral cortex. You use this each day for a variety of tasks,
including controlling motor functions, processing sensory data, and complex actions such as
reasoning and problem-solving. And this section can be further divided into four lobes which are
responsible for all kinds of functions from sight to decision making to touch.
If your brain has a “CPU” then this would be it. The cerebral cortex is where most data
processing occurs. It’s an intricate landscape of grey matter which includes peaks (gyri) and
valleys (fissures).
A wonder of evolution, every one of its six layers is different than the last. Each layer has a
different configuration of neurons and connections expertly suited to its many functions. It’s also
split into four lobes, all with specific tasks.
Diencephalon
As the second division of the forebrain, it relays sensory data and communicates with both the
endocrine system and nervous system. Here, autonomic and endocrine functions are performed.
The diencephalon also performs sensory and motor functions. Within the diencephalon are:
Thalamus: a network router and sorting station for your brain, sending, receiving and directing
data where it needs to go. It receives auditory, somatic, visceral, gustatory and visual data from
the lower centers. Then it shoots the information to the relevant departments for further
processing.
Here it’s decided which signals what needs conscious awareness and what should be ignored.
New data is compared with existing memory and you decide if your map of the world needs
updating. Not only that, but it’s also responsible for managing our circadian rhythm.

5. Hypothalamus: responsible for the fight or flight response, it has the ability to shut down the
rest of the brain when put in dangerous physical and emotional situations. It controls behavior
through regulating the release of hormones from the pituitary gland.
The pituitary gland hangs from the hypothalamus, and is known as the ‘master gland’ of the
endocrine system, It’s also the control center for breathing, blood pressure and body temperature.
This area secretes hormones that act upon the pituitary gland to regulate metabolism,
reproduction and growth.
Pineal Gland: known in spiritual circles as the “third eye”. This is known as our perceptual
center. It converts nerve signals to hormone signals. Thus, it’s our link between the nervous and
endocrine systems. It also produces melatonin, which is essential for your sleep-wake cycle.
Growing Your Superbrain
If lifelong learning is the key to a healthy brain, perhaps learning to learn faster could be your
superpower! And if that sounds good to you, perhaps learning about your brain is a great way to
start.
Because as Jim Kwik, Author of Mindvalley’s Superbrain Program, suggests, “We need to
understand how our minds work so we can work out minds better.”
