Sensory Motor Transformations in Human Cortex
NCT01964261 · View on ClinicalTrials.gov ↗
Study Summary
This research study is being conducted to develop a brain controlled medical device, called a brain-machine interface. The device will provide people with a spinal cord injury some ability to control an external device such as a computer cursor or robotic limb by using their thoughts along with sensory feedback. Development of a brain-machine interface is very difficult and currently only limited technology exists in this area of neuroscience. Other studies have shown that people with high spinal cord injury still have intact brain areas capable of planning movements and grasps, but are not able to execute the movement plans. The device in this study involves implanting very fine recording electrodes into areas of the brain that are known to create arm movement plans and provide hand grasping information and sense feeling in the hand and fingers. These movement and grasp plans would then normally be sent to other regions of the brain to execute the actual movements. By tying into those pathways and sending the movement plan signals to a computer instead, the investigators can translate the movement plans into actual movements by a computer cursor or robotic limb. A key part of this study is to electrically stimulate the brain by introducing a small amount of electrical current into the electrodes in the sensory area of the brain. This will result in the sensation of touch in the hand and/or fingers. This stimulation to the brain will occur when the robotic limb touches the object, thereby allowing the brain to "feel" what the robotic arm is touching. The device being used in this study is called the Neuroport Array and is surgically implanted in the brain. This device and the implantation procedure are experimental which means that it has not been approved by the Food and Drug Administration (FDA). One Neuroport Array consists of a small grid of electrodes that will be implanted in brain tissue and a small cable that runs from the electrode grid to a small hourgl

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01964261
The ClinicalTrials.gov registry entry for NCT01964261 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 5 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Richard A. Andersen, PhD, which has 29 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Quadriplegia appearing as the primary indexed condition, and to 1 intervention — of which Neural Prosthetic System 2 (NPS2) is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01964261 reports 4 study locations spanning 2 distinct geographic areas — top geographies include California, Colorado. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
