Re: Speech intelligibility and spatial information

Last week in Magdeburg, a neuroscientist explained that a single neuron
may respond to either auditory or visual stimuli. Why not imagine a
similar sharing of many neurons between sensory and motoric functionality?
However, if I interpret the presented physiological results correctly,
the switchover is rather sluggish.
BTW, sluggishness is not always unwelcome. It was the only way of pain
control when a surgeon removed an ulcer from the buttocks of the French king
Luis XIV by a few strikes with his scalpel.
Isn't the manual action of the blind supported by feeling instead of vision?
I guess, if we try and obstruct their feeling by thick gloves, their tuning
performance will decrease because they have to pay more attention to fine
