Research exists on craniopagus twins, maybe most notably Tatiana and Krista, who seem to share sensory input somewhat. I doubt that connective mechanisms such as this abnormal case would suffice to permit "compound cognition" in ways that would enhance cognitive ability similarly to your point about hominid evolution. Your relatively simple proposal for a ...

Mario Liotti and Don M. Tucker (Brain Asymmetry, MIT, 1996) attempt to explain that the 'corticolimbic architecture is not left/right, but dorsal/ventral". In their opinion, the reason for hemispheric asymmetries can be found in the asymmetries of the dorsal and ventral systems. They proposed that emotional behavior could be interpreted by analyzing the ...

Nick Stauner’s reply has some nice discussion about concrete existing work; we also discussed some more speculative possibilities in (Sotala & Valpola 2012), considering the possibility of merging together the minds of two distinct people so that they could share thoughts and skills. In particular, we considered the possibility of “exocortices”, neural ...

You may be interested in the FARS model from Fagg and Arbib (1999) that describes the interaction of the two visual streams in the primate brain during object grasping. The article What Puts the How in Where? Tool Use and the Divided Visual Streams Hypothesis (2007) makes use of the dorsal/ventral streams to explain our ability to use complex tool. As Frey ...

Henderson summarizes very well a number of approaches on human gaze control during real-world scenes and tasks. http://cvcl.mit.edu/iap05/henderson_03.pdf In a nutshell, our visual system combines knowledge about the task (e.g. color of the search target) and external audio/visual stimuli (saliency) to control our gaze inside a scene. Quite insightful about ...
