Can Nicotine Help to Treat Schizophrenia?
Several studies have indicated that schizophrenic patients are likely to show high levels of nicotine dependence. Scientists from Higher School of Economics (HSE), Institut Pasteur, the CNRS, Inserm and the ENS employed a mouse model to elucidate how nicotine influences cells in the prefrontal cortex. They visualized how nicotine has a direct impact on the restoration of normal activity in nerve cells (neurons) involved in psychiatric disorders such as schizophrenia. These findings were published in a paper that appeared in the journal Nature Medicine.
Alcoholism May Be Caused by Dynamical Dopamine Imbalance
Researchers from the Higher School of Economics, Ecole Normale Supérieure, Paris, Indiana University and the Russian Academy of Sciences Nizhny Novgorod Institute of Applied Physics have identified potential alcoholism mechanisms, associated with altered dopaminergic neuron response to complex dynamics of prefrontal cortex neurones affecting dopamine release.
Motor Cortex Influences Word Comprehension
Researchers from HSE, Northumbria University, and Aarhus University have experimentally confirmed the hypothesis, whereby comprehension of a word’s meaning involves not only the ‘classic’ language brain centres but also the cortical regions responsible for the control of body muscles, such as hand movements. The resulting brain representations are, therefore, distributed across a network of locations involving both areas specialised for language processing and those responsible for the control of the associated action. The results have been published in the journal Neuropsychologia.
What to Expect from Science in 2017: Neurolinguistics
In 2017, we expect neurolinguisitcs to continue developing such applications as standardized tests for speech deficiencies. Furthermore, there should be further joint work among neurolinguists and surgeons, as well as new emerging neurolinguistics-oriented therapeutic studies with the application of various neurovisualizational methods.

HSE Researchers Expand on Neuroanatomical Model of Semantic Aphasia
For the last 70 years, it was largely believed that spatial processing disorders, including those seen in language, occurred when the temporal-parietal-occipital (TPO) junction of the brain’s left hemisphere was damaged. But according to researchers from the HSE Neurolinguistics Laboratory, it is the damages to the axonal fibers connected to this area of the brain that are most important.
Voluntary Health Insurance Serves the Healthy and Wealthy
Voluntary health insurance schemes tend to enhance access to healthcare for those who are not much in need.
Performance Motivating Factors Reported by Russian Doctors
Interesting work, the desire to help patients, and money – these are the three key factors which motivate Russian doctors to perform, while career ambitions remain a secondary consideration, according to HSE research.

HSE Researchers Help Treat Cancer in Children
Many people in Russia know about the Dima Rogachev Centre – particularly those who have faced the challenge of child cancer. The centre is Europe's largest pediatric cancer care facility and is named after a boy with advanced cancer who wrote a letter to President Putin inviting him to visit; the invitation was accepted, and after the visit, the decision was made to build a state-of-the-art Centre for Pediatric Hematology, Oncology and Immunology, based in the Research Institute of Pediatric Hematology. The new centre was named after Dmitry 'Dima' Rogachev who died two years later at the age of 12 while the centre was still under construction.
