A customizable software program was developed for Ponemah to assess the internal physiological state of animals in real-time, providing valuable insights into mechanisms of neuropsychiatric diseases.
To further understand mechanisms of neuropsychiatric disease(s) and their impact on physiological systems, improved pre-clinical models and innovative methodology are needed to assess the internal physiological state of the animal in real-time. To address this challenge we developed a customizable software-based program for Ponemah (TM) that takes into account the animals diurnal and resting cardiovascular state in a home-cage environment. Using an integrated Pavlovian fear conditioning and cardiovascular telemetry approach in mice, we demonstrate for the first time a novel software add-on application that can remotely trigger a conditioned stimulus (CS) (i.e., audible tone) based on the animals instantaneous cardiovascular state while in its home-cage environment. This new software tool extends the ability to quantify integrated physiological correlates of learned threat and defensive behavior and may aid in further understanding mechanisms related to enhanced cardiovascular and autonomic arousal in anxiety-based disorders.
