1. A microsurgical tool, comprising:
- an endoscopically deliverable elongate structure configured so as to extend from an entry site within a body to a vicinity of an organ; and
at least one sensing tip electrically and mechanically coupled to the elongate structure, the at least one sensing tip being configured;
to interface with tissues in the vicinity of the organ;
to measure local neural activity associated with the tissues in the vicinity of the organ; and
to convey one or more electrophysiological signals associated with an electrophysiological activity;
wherein the at least one sensing tip comprises a clamp structure having an inner surface configured to contact the tissues in the vicinity of the organ and an outer surface opposite the inner surface; and
wherein the at least one sensing tip comprises;
a plurality of electrodes arranged on the inner surface of the clamp, the plurality of electrodes comprising one or more sensing electrodes configured to measure the local neural activity associated with the tissues in the vicinity of the organ; and
one or more additional electrodes arranged on the outer surface of the clamp, the one or more additional electrodes arranged on the outer surface of the clamp being configured to determine a reference signal used by the at least one sensing tip to cancel out ambient environmental action potentials and noise from measurements of the local neural activity by the one or more sensing electrodes on the inner surface of the clamp; and
wherein the clamp structure comprises a self-wrapping tool.
