Which individual is associated with the study of heart rate changes in response to mechanical irritation in infants?

The individual associated with the study of heart rate changes in response to mechanical irritation in infants is Koch. His research focused on understanding how different physical stimuli could affect physiological responses, particularly heart rate, in infants. This work helped pave the way for recognizing the significance of mechanical irritation and neurological responses, which are foundational concepts within chiropractic practice.

In addition to this specific focus, Koch's research contributes significantly to the understanding of reflexes and their impact on health, which correlates with chiropractic theories surrounding the nervous system's role in overall well-being. By studying these responses, Koch highlighted the connection between the body’s physical condition and its neurological functions, a fundamental aspect of chiropractic principles.
