چکیده
reflect this additional burden on syntactic processing in linguistic as compared to algebraic tasks. Concerning the algebraic reasoning task, does the absence of increased activity in IFGop and IFGtri imply an absence of involvement of linguistic syntax during algebraic reasoning? This would be true if the grammatical tasks did not require syntactic processing to be performed. Contrary to the authors’ claim, the grammatical evaluation of sentences cannot be considered a simple reading task, nature (linguistic or algebraic) of the reasoning process modulates the hemispheric contribution of parietal areas. On the whole, Monti et al.’s study does not demonstrate a strict dissociation between language and reasoning areas. Instead, to us, it suggests that algebraic reasoning could be supported by interactions between left hemisphere linguistic-syntax-related areas and right parietal arithmetic-related areas. Network analysis might be a fruitful method for further investigation of this question, by testing in the same individuals the variation of inter-hemispheric Spotlights Trends in Cognitive Sciences October 2012, Vol. 16, No. 10

Yes, There Is a Neural Dissociation between Language and Reasoning
In their commentary, Tzourio-Mazoyer and Zago (henceforth, TMZ) caution against the conclusion, presented in Monti et al (2012), that there exists a dissociation between algebraic and linguistic reasoning. In what follows we briefly summarize our experimental design and then show that TMZ's concerns spring from an inaccurate reading of our methods. In [1] we visually presented participants with...
متن کاملResponse Analysis of Neuronal Population with Synaptic Depression
In this paper, we aim at analyzing the characteristic of neuronal population responses to instantaneous or time-dependent inputs and the role of synapses in neural information processing. We have derived an evolution equation of the membrane potential density function with synaptic depression, and obtain the formulas for analytic computing the response of instantaneous re rate. Through a techni...
متن کاملA Comparison of Regression and Neural Network Based for Multiple Response Optimization in a Real Case Study of Gasoline Production Process
Most of existing researches for multi response optimization are based on regression analysis. However, the artificial neural network can be applied for the problem. In this paper, two approaches are proposed by consideration of both methods. In the first approach, regression model of the controllable factors and S/N ratio of each response has been achieved, then a fuzzy programming has been app...
