About the Department of Developmental Neurobiology
The human brain is by far the most complex structure on Earth. Consider that it contains a thousand billion neurons, of a thousand or more different, individual types, and that each neuron is wired up to as many as five hundred other neurons; this allows the possibility for a really vast number of alternative wiring configurations - more, it has been estimated, than there are molecules in the universe. Yet the elaborate pattern of connectional networks between neurons that constitutes the machinery for sensation, movement, emotion and thought, is remarkably similar between individuals. Indeed, the basic plan of the brain - the layout of its command and control centres and all but the smallest details of its wiring diagram - appears to be virtually identical between individual humans and recognisably similar between human and mouse.
Furthermore, this 'ground plan' of the brain is genetically determined, or 'hard wired', leaving only the fine details of network construction to be influenced by the electrical activity of circuits and environmental experience. Such is the complexity of the brain's construction, however, that neurobiologists are still far from a complete structural and functional understanding of its basic operations, such as those we have in common with chickens and mice, let alone even beginning to understand the nature of the higher functions - such as thought and consciousness - of which possibly only the human brain is capable.
It is our goal to further the understanding of this structure through our research programmes:
- Building brains: animal models and tissue engineering
- Assembly and Plasticity of Neural Circuits
- Neurodevelopmental Disorders
