gib65 Posted June 18, 2006 Posted June 18, 2006 What part of the brain is responsible for giving us the ability to write?
cpwmatthews Posted June 18, 2006 Posted June 18, 2006 Nice question, I would think it will be the frontal lobe as it takes in information from the eyes, the left and right parts of the brain would then dictate the 'colour' if you like of the words or symbals that are created.
gib65 Posted June 19, 2006 Author Posted June 19, 2006 That may be true for reading, but writing is what I'm wondering about. This probably is located somewhere in the frontal lobe, but if somebody knows a more specific location within the frontal lobe (or whatever lobe it is), I'd really like to know. Thanks
Genecks Posted June 19, 2006 Posted June 19, 2006 I'd assume the motor cortex, Wernicke's area, and the occipital lobe. However, it would probably go in a circle; a person would have to read or visualize what he or she was writing. The writing process may include other parts of the brain. Perhaps you could describe more about ability. Define ability within the context of your question.

scicop Posted June 19, 2006 Posted June 19, 2006 Well, when if comes to fine motor control, there is the involvement of dopamine from S.Nigra neurons that project to striatal nuclie involved in fine motor coordination, in particular the shell of the NuAcc. You want evidence? Parkinsons. DA neurons of the SN die. Therapy: dopamine replacement.
reor Posted June 19, 2006 Posted June 19, 2006 Isn't writing just like talking? Which parts are responsible for communication?
gib65 Posted June 19, 2006 Author Posted June 19, 2006 Isn't writing just like talking? Which parts are responsible for communication? Broca's. From Broca's area, the signals are sent to the motor cortex, which send signals to the larynx (there might be some intermediate neural centers). But I don't think it's as simple as saying that Broca's area must send signals to the part of the motor cortex responsible for our hand movements - that's not how the brain works. Broca's area would have to code the signals differently so that the hands get the right pattern of signals. The way the brain usually handles cases like this is that it either uses a different neural center other than Broca's or Broca's sends the signals to an intermediate neural center for converting the signals to the proper format, and then sends them to the motor cortex.
