Therefore, "active Ca" plays a significant role in neural facilitation.

This can be explained by neuroscience in terms of neural facilitation and short term plasticity.

Neural facilitation may be involved in several neuronal tasks, including simple learning, information processing, and sound-source localization.

Neural facilitation in neuroscience, is the increase in postsynaptic potential evoked by a 2nd impulse.

Neural facilitation (Short-term plasticity)

Depending on the time scales over which it acts synaptic enhancement is classified as neural facilitation, synaptic augmentation or post-tetanic potentiation.

The mechanisms underlying neural facilitation are exclusively pre-synaptic; broadly speaking, PPF arises due to increased presynaptic Ca concentration leading to a greater release of neurotransmitter-containing synaptic vesicles.

The advantage for RT to combined visual-tactile stimuli over RT to the other types of stimulation could be accounted for by intersensory neural facilitation rather than by probability summation.
