Neuroscience
Explore how neurons, circuits and brain chemistry give rise to movement, memory and thought.
What this field studies
Your brain has around 86 billion neurons, each connected to thousands of others. Neuroscientists study how those connections form, strengthen and fade — and how that activity becomes perception, behaviour and memory.
Questions researchers are asking
- How does the brain physically change when you learn something new?
- What happens in the brain while we sleep, and why do we need it?
- How do neural circuits change with practice?
- What goes wrong in conditions such as Alzheimer's or Parkinson's disease?
