Modular neuronal networks

This project concerns with a novel approach to pattern cultured neural networks into well defined modular structures. Using these modular networks we are studying the interplay between structure and form in neural networks. We observe that modularity allows neural networks to be connected in a contextual manner: Information is transferred only above a certain threshold in a particular direction. This contextual information transfer depends strongly on the balance between excitation and inhibition.

Carbon Nanotube Neural Interfaces

We are using nanotechnology, in particular carbon nanotube technology, to build interfaces for neuronal system. We use these inetrfaces both for basic investigations as well as to develop new electrodes for future neural implants. 


Nanorectennae: A new approach to rectify solar energy.

Neuronal Entanglement

Neurons appear to favor rough surfaces. The underlying mechanisms is not well understood and we are trying using various approaches to explore this effect. Using confocal flourescent imaging we were able to show how neurons and glia cells bind to three dimensional carbon nanotubes suggesting that neurons have an innate tendency to interwine into three dimensional support. 

Engineered Neural Circuits

Engineered neural networks are used to investigate the interplay between function and form in neuronal systems.

Neuronal Mechanics

Locust neurons are used to explore mechancial effects affecting neuronal development. We use micro suspended beams and carbon nanotube islands, to monitor the cells.

Mapping Neuronal Recording and Stimulation

Combined MEA and Ca recordings is used to explore to better understand micro neuronal recording and stimulations.

Flexible micro electrodes

We are using carbon nanotube technology to develop superior flexible electrodes for neuronal interfacing. These electrodes alllow not only simple fabrication scheme but also offer high durability, low stimulation threshold and simple integration with other advanced technologies.
