Electrical stimulation of the SC can evoke motor behavior.

Electrical stimulation of the cat SC can evoke saccades.

Typically, these saccades go into that general direction in which natural stimuli would lead to activation in the area that was electrically stimulated.

The `foveation hypothesis' states that the SC elicits saccades which foveate the stimuli activating it for further examination.

Ablation of the superficial SC does not result in blindness or orienting deficiencies. Only when the deep SC is ablated do these deficiencies occur—a remarkable finding considering that the superficial SC is the main target of retinotectal projections.

The uni-sensory, multi-sensory and motor maps of the superior colliculus are in spatial register.

Maybe attention controls whether or not multi-sensory integration (MSI) happens at all (at least in SC)? That would be in line with findings that without input from AES and rLS, there's no MSI.

Are AES and rLS cat homologues to the regions cited by Santangelo and Macalluso as regions responsible for auditory and visual attention?

Multiplying probabilities is equivalent to adding their logs. Thus, working with log likelihoods, one can circumvent the necessity of neural multiplication when combining probabilities.

Multisensory integration, however, has been viewed as integration of information in exactly that sense, and it is well known that multisensory neurons respond super-additively to stimuli from different modalities.
