Olds and Milner located reward centers in the brain structure known as the A. hypothalamus.
In the 1950s, psychologist James Olds and physiologist Peter Milner conducted a series of experiments in rats that helped to identify the brain regions responsible for reward. They found that when electrodes were implanted in certain areas of the hypothalamus, rats would press a lever repeatedly to receive electrical stimulation, suggesting that this region of the brain was associated with reward and pleasure. The hypothalamus is a small, almond-shaped structure located at the base of the brain that is involved in regulating many important functions, including hunger, thirst, mood, and endocrine function. Olds and Milner's findings laid the foundation for further research into the brain's reward system and how it is involved in the development of drug addiction and other behavioral disorders.

The heart rate percentages used in determining target heart rate zones represent the intensity of exercise.
What do you mean by heart rate?
Heart rate is the number of times a person’s heart beats in a minute. It is an important indicator of a person’s health and is typically measured by counting the number of times the heart beats in one minute while at rest.
