What is Neuroscience?

Neuroscience is the study of the nervous system, which is one of the last great frontiers of knowledge. Neuroscience research spans from molecules, through cells and pathways, all the way up to complex human behaviour. Neuroscience integrates physics, chemistry, and biology, with studies of anatomy, physiology, and behaviour including human emotional and cognitive functions.

Neuroscientific research may focus on:

  • understanding the human brain and how it regulates the body and behaviour, including giving rise to consciousness;
  • finding ways to prevent or cure neurological and psychiatric disorders.

Neuroscientists use tools such as:

  • antibodies and gene probes to identify proteins responsible for brain function;
  • fluorescent dyes to mark neurons and synapses with specific characteristics;
  • microelectrode arrays to study the activity of living neurons in real-time;
  • behavioural methods to study the processes underlying behaviour in humans and in animals;
  • computational models of neurons and their connections in the brain.
