However, being responsive to multiple sensory modalities does not guarantee that a neuron has actually engaged in integrating its multiple sensory inputs rather than simply responding to the most salient stimulus. A common response measure for both uni- and crossmodal stimulation is the mean, or the absolute number, of impulses (spikes) registered within a fixed time interval after stimulus presentation. The traditional criterion for identifying \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"multisensory enhancement\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\" is a statistically significant increase of the response measure elicited by a crossmodal stimulus compared to the value of the response measure to the most effective of the individual components. Here we propose a probabilistic foundation for a slightly modified criterion and argue that it is more powerful than the traditional criterion. }, note = {http://www.researchgate.net/publication/280574541} }
