Neurophysics


    • Extracellular recording from dissociated neuronal cultures, from retinas and from hippocampal slices. Recordings performed at very high spatial (7.4 µm) and temporal resolution (6-40 kHz).
    • Electrical stimulation of single neurons and of neural tissue (retina)
    • Investigations of cellular damage
    • Characterization of contact properties of neural tissue interfaced to substrate-integrated planar electrodes

      Techniques, methods, equipment
