System Integration
What you can do now is look simultaneously at all 150-200 presynaptic neurons that give input to your postsynaptic neuron and what they do at a given moment. You can really start to analyse how the brain computes in real time.

Every FEMTO3D Atlas ships with the team behind it
Installation, training, and ongoing support are handled directly by Femtonics engineers, not a distributor. From first light to advanced experiments, the people who built the system are the ones helping you run it.
Control the FEMTO3D Atlas the way you actually work
Acquisition, scanning parameters, and real-time monitoring in one interface. Set your targets, run the experiment, and move straight into analysis without switching tools.
Add FEMTO3D Atlas to your experiment
