Grossenbacher and Lovelace's (2001) 'Disinhibited-Feedback' Theory Proposes That

Grossenbacher and Lovelace's (2001) 'disinhibited-feedback' theory proposes that

A) connections between different sensory pathways exist in 'normal' brains, but are usually inhibited
B) connections between different sensory pathways do not exist in 'normal' brains, as they are inhibited at a young age
C) neural connections between different sensory pathways exist only in the brains of synaesthetes
D) connections between different sensory pathways are inhibited in cases of synaesthesia
