Though the two hemispheres in the brain have separate functions, there is typically no overall dominant side — both constantly work together to help us complete daily tasks.

Learning something new doesn’t generate new brain cells, but continued learning does create stronger connections between neurons. Here’s how.

Neural circuits link several brain regions together — shaping our behaviors, actions, thoughts, and emotions. Habits are formed when certain circuits are repeatedly activated and strengthened.

Various types of tics affect millions of people. A buildup of neurotransmitters in parts of the brain responsible for movement may be behind this neurological condition.

Seizures common in epilepsy disrupt the neural symphony orchestra performing in your brain. New advances in AI can help reveal novel treatments for the disorder.

Conspiracy theories take advantage of our pattern-seeking brains by grabbing attention, triggering strong emotions, and giving meaning to random events. Researchers think dopamine could be to blame when people forgo the facts for fiction.

Are you really in control of the decisions you make?

Chronic loneliness harms our brains and bodies.

Specific damage to the brain can prevent you from producing intelligible speech.

Much like neural networks in the brain, artificial neural networks adjust the strength of their connections with repeated exposure to data to perform certain functions.
