These VMH and peripheral glucose metabolism effects of circadian‐timed bromocriptine may involve its known effect to reduce elevated VMH noradrenergic activity in insulin‐resistant states as local VMH administration of norepinephrine was observed to significantly inhibit VMH GE neuronal sensing of local hyperglycaemia in insulin‐sensitive animals on regular chow diet (52.4%). Here, INS is linked to Hyperglycemia.
