Scientific Research and Scientific Dissemination Projects

In Progress

2012 -

Walk Again Project

The primary mission of the Walk Again Project was the creation of the first human brain-controlled exoskeleton to restore gait in people with lower-limb paralysis.Result of the collaborative research of the Walk Again international consortium, the exoskeleton was successfully developed, presenting not only a brain-controlled interface but also a sensory substitution system that provides to the user the sensation that its foot touches the ground during the walk. The feasibility of the exoskeleton was publically demonstrated at the 2014 Word Cup opening ceremony in Brazil by one of the research volunteers that performed the inaugural kick (and felt the touch of the ball !).

Besides the development of the exoskeleton, the Walk Again Project had other two unprecedented results, of great scientific impact, and enormous potential to help people with spinal cord lesion: the creation of the Neurorehabilitation Protocol - a training routine combining the use of a brain-machine interface, virtual reality, and sensorial substitution that, when systematically applied, resulted in partial neurological improvement in paraplegic volunteers; and the brain-controlled muscle stimulation system – a technology that allows the paraplegic user to walk using brain control, and minimal assistance.

The first phase of the Walk Again Project was held from December 2012 to June 2019, with financial resources from FINEP (Financing Agency for Studies and Projects). A new phase is being implemented, still focusing on the application of brain-machine interfaces in neurorehabilitation.



Master's Program in Neuroengineering

The Master's program in Neuroengineering, recognized and recommended by the Technical and Scientific Council (CTC) of CAPES, was another initiative of AASDAP to strengthen scientific education, and it was the first graduate program in neuroengineering in Brazil. Since 2014, the coordination of this program has been carried out by the Santos Dumont Institute (ISD).


Brain-Machine Interface Institute of Science and Technology (INCeMaq).

Project under the Program of National Science and Technology Institutes of the National Council for Scientific and Technological Development (CNPq/MCT), focused on the research on the Brain-Machine Interface (BMI). The project was effective from 2009 to 2017 and had resources from CNPq and FAPERN.

The research lines developed in INCeMaq were: Brain-Machine Interface – development and biocompatibility of multielectrode matrices, decoding of the activity of neuronal populations and generation of commands for devices;

Spinal Cord Neuromodulation – development of epidural stimulation electrodes; behavioral, electrophysiological, and immunohistochemical evaluation of the effects of the stimulation.

Among the studies carried out under the INCeMaq, we can mention the first technological development activities of the Walk Again Project.

In addition to the basic and applied research on BMI, INCeMaq also had a program of scientific initiation for high school students of the public schools of Natal and Macaíba, named Scientists of the Future. The Program of Scientists of the Future provided activities with scientific content at the science frontier and allowed the insertion of 54 students in the practice of data collection and interpretation, in the discussion, and in the application of solutions in real challenges. The activities of the Project of Scientists of the Future are described in the photo book.

2003 - 2005

Implementation of the International Institute of Neuroscience of Natal

The International Institute of Neuroscience of Natal (IINN) was created based on the premise that countries investing in science achieve great social changes, reflected by the growth of their gross domestic product (GDP). Thus, investment in science could be the key to reducing the existing economic and social inequalities between Brazil and developed countries, but mainly for reducing existing inequalities within Brazil, between its geographic regions.

In this context, the IINN project's main objective was to establish a “Brain Campus” in a Brazilian region with a low human development index (HDI) and located outside the Rio-São Paulo axis of investments in Science and Technology (S&T). This campus - containing centers for scientific research, education, and health - would allow the science produced there to permeate and transform the local community through education, health care, and technological development.

The location chosen for the establishment of the IINN was the greater Natal, in northeastern Brazil. For the benefit of the nation's science and development, the IINN would attract resources to a region historically neglected not only in S&T investments but also in education and health.

The implementation of the IINN took place between 2003 and 2005, with fundraising and the establishment of partnerships, the creation of a legal organization for project management, and the definition of strategies for the beginning of the activities. The first resources for the IINN were obtained by Dr. Nicolelis from Duke University, Avina Foundation, Hospital Infantil Sabará, Hospital Sírio Libanês, and partnerships with the federal government. Additional funds were raised through the initiative of individual supporters. Important partnerships were also established with UFRN and the government of Macaíba city, resulting in the donation of land in Macaíba city (29km from Natal) to house the Brain Campus and a Health Center.

Due to its greatness and innovation, the IINN project received prominence in local, national, and international newspapers, including Nature and Science, two of the most important scientific journals in the world. In March 2004, during the 1st IINN Neuroscience Symposium, the project was officially launched, with the support of renowned neuroscientists from around the world.

Since the creation of the Alberto Santos Dumont Association for Research Support (AASDAP) in April 2004, the implementation of the IINN has moved forward with an alternative work proposal. Faced with the prospect of delaying the start of the works on the Brain Campus, AASDAP started the establishment of pilot IINN units. As a result, research, education, and health activities started respectively in 2005, 2007 and 2008, in Natal and Macaíba. Over the years, the establishment of partnerships and projects has enabled these units to become centers of reference, proving the viability of IINN, even in its “alternative” format.
