Enhanced Tactile Memory in the Blind
NCT00076700 · View on ClinicalTrials.gov ↗
Study Summary
This study will determine if the brain regions in blind people that would normally be involved in vision are used instead to remember touch. Blind people have an enhanced sense of touch compared to sighted people, and they also perform better on tests for certain kinds of memory. This study will examine and compare the results of a touch memory test in blind and sighted people to determine what brain areas are involved in responding to touch. Blind people and sighted volunteers between 18 and 80 years of age who have no psychiatric problems or neurological problems (other than blindness) may be eligible for this study. Candidates are screened with a medical interview and examination. Participants undergo one or both of the following procedures: Behavioral experiment Sighted participants are blindfolded during this experiment. Subjects sit comfortably in front of a table. They are presented with a number of surfaces placed on a table one at a time and are given 10 seconds to feel each surface with the index finger on their dominant hand. They must concentrate and memorize the surfaces as best they can. After a 15-minute break, they are again presented with a series of surfaces and given 10 seconds to feel each one. This time, they must say as quickly as possibly whether the surface is one they touched previously or is a new surface. Functional MRI MRI uses a strong magnetic field and radio waves to obtain images of body organs and tissues. In this study, subjects undergo MRI scanning of the brain while performing the same touch test described above. For the MRI, the subject lies on a table that slides into the scanner. The MRI machine detects change in the brain regions involved in performing the task.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00076700
The ClinicalTrials.gov registry entry for NCT00076700 describes a study currently listed as completed. It is categorized as an unspecified phase, 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 45 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 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 Blindness appearing as the primary indexed condition, and to 0 interventions. 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: NCT00076700 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. 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.
