1-20. (canceled)
An implant assembly for sensing neural activity of a subject, comprising:
- a hub member;
- a plurality of electrodes each having a proximal end connected to the hub member such that the proximal ends of at least a portion of the plurality of electrodes are at non-parallel angles to each another, and each having a distal end extending from the hub member;
- a connector attached to the hub member;
- and
- a plurality of electrical traces in communication with the connector, and extending through one or more portions of the hub member and at least a portion of the plurality of electrodes, wherein a portion of each electrical trace is exposed on one of the electrodes to form a transducer site that is adapted to convert sensed electro-chemical physical reactions present in the neural tissue of the subject into electrical signals, and wherein the electrical traces are adapted to transmit the electrical signals to the connector.

- and
- a plurality of electrical traces in communication with the connector, and extending through one or more portions of the hub member and at least a portion of the plurality of electrodes, wherein a portion of each electrical trace is exposed on one of the electrodes to form a transducer site that is adapted to convert sensed electro-chemical physical reactions present in the neural tissue of the subject into electrical signals, and wherein the electrical traces are adapted to transmit the electrical signals to the connector;
- implanting the implant assembly at the site such that the electrodes surround a tissue volume of interest;
- and
- connecting the implant assembly to a recording device configured to receive electrical signals from the transducer sites.
