Disclosed herein is a brain stimulation apparatus. The brain stimulation apparatus can comprise an electrode disposed on a scalp of a subject and configured to simultaneously stimulate and record from a same site of the scalp. The electrode can comprise a comb shape comprising a plurality of tube-like prongs, each of the plurality of prongs extending down to touch the scalp. The brain stimulation apparatus can comprise a first input to the electrode connecting a first subset of the plurality of prongs to a stimulator for driving a transcranial electrical stimulation (TES), and a second input to the electrode connecting to a second subset of the plurality of prongs to an Electroencephalograph (EEG) recorder. The first input and the second input can be disposed interleaved to enable direct noise cancellation.

This disclosure describes various modular electrode assemblies. For example, an implantable modular electrode assembly may include a hub including a plurality of electrical contacts configured to receive electrical signals from an implantable medical device, a first electrode module including a first substrate and a first plurality of electrodes on the first substrate, and a second electrode module including a second substrate and a second plurality of electrodes on the second substrate. The first and second electrode modules may be connectable to the hub, where the plurality of electrical contacts electrically communicate with the first and second plurality of electrodes.
Abstract:
An apparatus and method is provided for intraoperative tissue stimulation during port-based surgery. The apparatus includes an access port and electrical terminals attached to the access port for tissue stimulation. In an alternative embodiment, the apparatus may include an access port, with or without electrical terminals attached to the access port for tissue stimulation, and electrocorticography sensors attached to the access port. The method includes inserting an access port into a tissue, applying an electrical potential to the tissue using electrical terminals attached to the access port, and measuring consequent neural activity using electrocorticography sensors attached to the access port.
Abstract:
Systems and methods for providing neural stimulation and recording on a subject using flexible complementary CMOS probes are provided. Disclosed systems can include a flexible probe adapted for insertion into a portion of a brain of the subject, the flexible probe comprising a tail portion and a head portion. The tail portion can include a plurality of electrodes configured to be coupled to the brain and a plurality of front-end amplifiers. Each of the plurality of front-end amplifiers can be configured to amplify a signal received from a corresponding electrode of the plurality of electrodes. The head portion can include one or more inductors configured to enable two-way communication with a wireless reader through a near-field inductive link.
Abstract:
An electrical stimulation lead or lead extension includes a body having an outer surface, a proximal end, a proximal portion, at least one distal portion, an outer surface, a perimeter, and a longitudinal length, the body defining an alignment slit extending distally from the proximal end of the body and splitting the proximal portion of the body into two transversely space-apart sections; first contacts disposed along the distal portion of the body; segmented second contacts disposed along the proximal portion of the body, where each segmented second contact extends around less than the entire perimeter of the body and is separated from all other segmented second contacts by portions of the body or the alignment slit; and conductors electrically coupling the first contacts to the second contacts.
Abstract:
Systems and methods are disclosed for selectively reinforcing or weakening memory associations. At least one current generator provides an electrical current including a plurality of oscillating pulses with at least one predetermined frequency. A user interface includes at least one output device for delivering a sensory stimulus to a user and at least one user input device for registering a response to the stimulus. At least one processor determines from the response, based on at least one predetermined standard, whether an underlying memory association is desired or undesired and respectively sets the at least one predetermined frequency to be a beta or theta frequency. Consequently, the electrical current is generated and administered, via at least one electrode pair, thereby stimulating at least one specific portion of the user's brain so as to reinforce or weaken the underlying memory association.
