                         recently proposed informational quantity, the causal mutual 
                         information, employed with an appropriate methodology, can be used 
                         not only to correctly infer the direction of the underlying 
                         physical synapses, but also to identify their excitatory or 
                         inhibitory nature, considering easy to handle and measure 
                         bivariate time series. The success of our approach relies on a 
                         surprising property found in neuronal networks by which 
                         nonadjacent neurons do understand each other (positive mutual 
                         information), however, this exchange of information is not capable 
                         of causing effect (zero transfer entropy). Remarkably, inhibitory 
                         connections, responsible for enhancing synchronization, transfer 
                         more information than excitatory connections, known to enhance 
                         entropy in the network. We also demonstrate that our methodology 
                         can be used to correctly infer directionality of synapses even in 
                         the presence of dynamic and observational Gaussian noise, and is
