Cuban Neurosciences Center

Cuban Neurosciences Center

The Cuban Neurosciencies Center (CNEURO) is located in Playa, Ciudad de la Habana province. It was founded in 1969 as one of the first groups in the world to use informatics for the analysis of the brain`s electrical activity. The Cuban Neuroscience Center was officially established in 1990 and it was considered as an independent unit on January 1,, 2005. Nowadays CNEURO is one of the institutions of the Scientific Pole devoted to the development of technology and the carry out of basic researches closely related and according to the main mental health problems of Cuban population.

CNEURO`s Main Achievements

1- Execution of several medical projects with high social impact (covering important population groups) related to disabilities caused by neural dysfunction such as:

  • Inclusion of methods for the early detection of hearing loss in children.
  • Introduction in Cuba, along with other institutions, of the cochlear implant technology to restore hearing to deaf and more recently to deaf-blind.
  • Inclusion of different methods to diagnose and carry out epidemiological studies on learning disabilities and behavior in school children.
  • Development of epidemiological studies on autism and other neurodevelopmental disorders.
  • Development of epidemiological studies and new early detection methods related to dementias and Alzheimer's disease.
  • Improvement of psychiatric diagnosis, along with the Cuban Public Health Ministry, with emphasis on schizophrenia, and at the same time development of other epidemiological studies about this disease.
  • Development of microorganism’s rapid typification methods for molecular epidemiology and the establishment of appropriate technology.

2 - Development of strategic cutting-edge researches on current neuroscience issues such as:

  • Acquisition of knowledge on the basic mechanisms underlying mental processes such as face recognition, selective attention, and emotions.
  • New neuroimages processing methods including brain electrical tomography, images fusion methods in different modalities (e.g. MRI and EEG) and different methods to study brain connectivity.
  • Characterization of the basic psychological and neural processes maturation in schoolchildren.
  • New methods to characterize the sensory auditory and visual processes.
  • Macromolecular biophysics.

3 – Development of products, medical equipments, specialized software and other resources for the neurophysiologic diagnostic. CNEURO licenses these products to NEURONIC SA. , that is responsible for the production and marketing of these products.

4 - Coordination of the National Program in Science and Technology for neurosciences and neurobiology emerging technologies.

5– Development of care for the country`s National Network of Clinical Neurophysiology Laboratories (57) and provision of technical assistance services. The network was created with technology developed by CNEURO.

6 - Functioning as the only unit authorized by the Ministry of Public Health for the Clinical Neurophysiology residency. In response to post grade`s requests from neurologists, neurophysiologists, psychiatrists, educators and defectologists it has also received post-doctoral students from Germany, Japan and Switzerland.

7- Development of a Neuroscience Master Program authorized by the Cuban Higher Education Ministry.

8 -Coordination of the National Cochlear Implant Program for deaf and deaf blind patients generated by our center and developed in collaboration with institutions of the Ministry of Public Health and the Ministry of Higher Education.

9- Generation of new knowledge and international contributions through a new patent portfolio in some countries such as, USA and South Africa. Furthermore, there is a great amount of scientific publications on high impact magazines which are registered in an international data base.
