Is it possible for technologists to insert chips on our hearts to control our thoughts and emotions?

It may be possible to put chips on our hearts to control our heart rate, but I doubt they could do much about thoughts and emotions from a heart-bound chip.

You could simulate an adrenalin rush by rapidly increasing the heart rate - this could lead to panic, fear etc.  But more subtle mood changes would require interfering with the brain, both chemically and electrically, which is a bit more complicated.

Isn't that the wrong way round? I thought adrenalin caused an increase in heart rate not vice versa.

Sorry, simulate an adrenalin rush by increasing the heart rate, not stimulate an adrenalin rush.

I'm still not convinced. Adrenalin does more than just increase the heart rate. It can also cause a temporary override of muscular inhibition which would allow increased speed when running, greater strength, and even make the person braver. Simply increasing the heart rate would not cause those other effects.
