abstract = {Mechanical stimulation is a promising means to
non-invasively excite and modulate neuronal networks with a
high spatial resolution. Despite the thorough
characterization of the initiation mechanism, whether or how
mechanical responses disperse into non-target areas remains
to be discovered. Our in vitro study demonstrates that a
single-neuron deformation evokes responses that propagate to
about a third of the untouched neighbors. The responses
develop via calcium influx through mechanosensitive channels
and regeneratively propagate through the neuronal ensemble
via gap junctions. Although independent of action potentials
and synapses, mechanical responses reliably evoke membrane
depolarizations capable of inducing action potentials both
in the target and neighbors. Finally, we show that
mechanical stimulation transiently potentiates the
responding assembly for further inputs, as both gain and
excitability are transiently increased exclusively in
neurons that respond to a neighbor’s mechanical
stimulation. The findings indicate a biological component
affecting the spatial resolution of mechanostimulation and
point to a cross-talk in broad-network mechanical
stimulations. Since giga-seal formation in patch-clamp
produces a similar mechanical stimulus on the neuron, our
findings inform which neuroscientific questions could be
reliably tackled with patch-clamp and what recovery
post-gigaseal formation is necessary.},
