Facts about your brain you didn't know until now. List of facts about the brain that will enlighten you further.
The average adult human brain weighs about 3 pounds and is roughly the size of a grapefruit.
How Big Is a Human Brain? Learn About Brain Size and Brain Weight
The brain uses about 20% of the body's total energy, even though it only makes up about 2% of the body's mass.
How Much Energy Does the Brain Use?
The brain is composed of grey matter (primarily neuron cell bodies) and white matter (primarily axons connecting neurons).
Grey Matter vs White Matter in the Brain
The human brain contains approximately 86 billion neurons, which are specialized cells that transmit information.
Brain Basics: The Life and Death of a Neuron
Neurons communicate with each other through trillions of connections called synapses.

The brain is remarkably plastic, meaning it can change and adapt throughout life in response to learning and experience. This is called neuroplasticity.
Neuroplasticity - StatPearls
The brain is divided into two hemispheres, the left and right, each with specialized functions. While there's some specialization, they work together.
Left Brain vs. Right Brain: What's the Difference?
The outer layer of the brain, the cerebral cortex, is responsible for higher-level cognitive functions like thinking, reasoning, and language.
Cerebral Cortex: What It Is, Function & Location
The cerebellum, located at the back of the brain, plays a crucial role in motor control, coordination, and balance.
Cerebellum: What It Is, Function & Anatomy
The brainstem connects the cerebrum and cerebellum to the spinal cord and controls essential life functions like breathing and heart rate.

Sleep is crucial for brain health, allowing it to consolidate memories and clear out waste products.
How the brain controls sleep
The brain receives a constant supply of oxygenated blood through a network of blood vessels.
Arterial Supply to the Brain - Carotid - Vertebral
The brain is protected by the skull, meninges (protective membranes), and cerebrospinal fluid.
Meninges: What They Are & Function
The brain generates its own electromagnetic fields, which can be measured using an EEG (electroencephalogram).
the possible role of brain electromagnetic fields (As a Potential ...
The speed at which the brain processes information is incredibly fast, measured in milliseconds.
Processing Speed: What It Is, Conditions & How To Improve It
Brain structure and function vary significantly between individuals.
