Citation: Becchetti A and Wanke E (2015) Commentary: " Comparison of spike parameters from optically identified GABAergic and glutamatergic neurons in sparse cortical cultures. " Because of the increasing use of multi-site extracellular recording from neuronal networks, it would be extremely useful to determine reliable ways to distinguish with this method the main neuronal populations in vivo ...

Mond-Weir type duals for multiobjective variational problems are formulated. Under generalized vector variational type I invexity assumptions on the functions involved, sufficient optimality conditions, weak and strong duality theorems are proved efficient and properly efficient solutions of the primal and dual problems.
