New method proves long-held theory about dopamine modulation during decision-making processes

Mathematical computing techniques developed by Dr Emili Balaguer-Ballester at Bournemouth University, and a team of neuroscientists at Indiana Purdue University in US, the University of Heidelberg in Germany and British Columbia in Canada have been used to map the effects of neurotransmitters, such as dopamine, on neural activities and behaviour. This has enabled the team to prove a long-held assumption in computational neuroscience: that cognitive decisions seem to be represented by temporarily stable states of neural dynamics which are modulated by dopamine. Until the publication of a new study, based on the application of their method, this theory remained insufficiently evidenced. “The methodology takes techniques from functional analysis, machine learning and dynamical systems and applies them to areas such as neuroscience,” explains Dr Balaguer-Ballester. “By mixing up approaches from different…
