If there is a discrepancy between the actual and expected stimuli (ie, novelty or uncertainty), or if the predicted stimuli are aversive, the bis is activated, arousal and attention to novel environmental stimuli is increased, and ongoing behaviors arc inhibited. Significant decrease in mean heart rate (hr) and increases in sdnn (standard deviation of the normal-to-normal (nn) intervals), rmsdd (square root of the mean squared differences of successive nn intervals), and hf (high frequency) of spectral powers analysis after lavender inhalation were observed in the 4th and 12th weeks of aromatherapy.

Heart rate variability, the change in the time intervals between adjacent heartbeats, is directly related to the body's interdependent regulatory systems and ultimately, their efficiency and health an optimal level of hrv within an organism reflects healthy function and an inherent self-regulatory capacity, adaptability, or resilience. However, it must be understood that fig-2, which shows the relationship between the two, is based on a pacinian corpuscle from the cat mesentery and does not represent all types of receptors mathematical attempts have been made to predict the receptor potential from the strength of the stimulus but have thus far been inaccurate when applied to.
