Neuron Activity Simulator - Version v.2.01 Neuron activity simulator is oriented towards professional, students and researchers. It's designed to be intuitive (No learning curve), all what you need is on one screen. In just few mouse clicks you can specify your experiment head model and visualizes your Electric potential (graph or/and data). Nas is regularly updated with most recent algorithms from scientific publication and from experts feedback (researchers, students in biomedical engineering, neurosciences and for EEG and tMS/tDCS technicians). All future upgrades are free ! Features: 1- Nas displays in real times user's neural activity (dipole moment and position) and simulated electrical potential. Numerical values at each electrode can also be saved in text editable file 2-Inter-hemispheric view, slicing plans, zoom +/-, 3-Axis (Jean Talairach axis or Cartesian), Anatomic layers view (MG, CSF, Skull, and Scalp), 4-Sensors systems. 5-Algorithm uses you input in real time to: Calculate and display electric potential on you 3D head model. Display 10-20 electrode system and electric potential for each
