Sending data from EEG sensor connected to Arduino over rf using radio head

The other question I have is if you think I would need to send both Brain.readErrors and readCSV.

You were sending the data to the serial port, in a way that made it impossible to distinguish one from the other. I have no idea what you saw, or how you distinguish one from the other. Therefore, I have no idea which data you want to send.

// RF Transmission container
char Brainmsg[1];

One? Why one? Surely you sent more than one character.

        for (i = 0; i < buflen; i++)
    {           
          // Fill Sensor1CharMsg Char array with corresponding
          // chars from buffer.   
          Brainmsg[i] = char(buf[i]);

You have just stomped all over memory you don't own.
