Do you mean that, if brain is for movement, then what are the neurones in the heart for ?
Like all neurones they transmit and process a signal. I don't know what the neurons in the heart do exactly.
But if I had to guess :
the brain send signals to the heart to control its frequency and things like that.
Maybe (probably) there is sensory neurons in the heart that measure various physiological factors, and this information is taken into account when the brain says to accelarate or decelerate.
Because the heart is not like some pump that makes n rotation by minute. So knowing how much it should increase/descrease its frequency maybe isn't enough for him, it need more data.
It's not like it just have to flip a single cursor, it has to manipulate several processes so that in the end, it translate into beats per minute, volume ejected, etc..
For example, all the muscle cells don't get contracted at the same time, different zones get contracted/relaxed at different times. Because the heart is not like a linear piston going up and down,
Muscle cells conctraction is triggered by a nervous signal. A important factor is the conductivity and speed of that signal through the nerves.
I'm not sure but I think regulating the conductivity of the nervous stimuli is how frequency get changed.
And to accurately control this probably requires lot of sensory neurons to obtain data, and this data needs to be processed so that effector neurons do the right thing
