Its Greatest Mysteries

The human brain is one of the most complex structures known to science. Despite centuries of study, researchers are still uncovering new insights about how it works.

What Makes the Brain So Powerful?

The human brain contains approximately 86 billion neurons, all connected through trillions of synapses. These connections allow us to think, feel, remember, and make decisions.

How the Brain Communicates

Neurons communicate using:

• Electrical signals within cells
• Chemical signals (neurotransmitters) between cells

These tools allow scientists to study the brain without invasive procedures.

Brain Disorders and Scientific Progress

Brain research has improved understanding of conditions such as:

• Alzheimer’s disease
• Parkinson’s disease
• Depression and anxiety
• Epilepsy

New treatments, therapies, and medications continue to emerge from neuroscience research.

Can Science Fully Understand the Brain?

While progress is impressive, the brain remains partly mysterious. Consciousness, creativity, and emotions are still not fully explained. Scientists believe interdisciplinary research—combining biology, psychology, and AI—will unlock further answers.
