Prolonged JAR Graph Analysis

This graph shows us that after prolonged exposure to a similar frequency the Apteronotus albifrons returns to its original frequency. The fish?s original frequency is 950.12 Hz. After being exposed to an artificial frequency of 950 Hz for 5 hours the Apteronotus albifrons raised its frequency to 968.52. After we turned off the electrodes, the fish?s frequency oscillated between 965 Hz and 971 Hz. We believe that the oscillations are part of the fish?s natural process of returning to its original frequency. After 35 minutes the fish?s frequency began to decrease linearly at approximately 0.7 Hz per minute until it reached a frequency of 956.284 Hz after one hour. In 5 hours the fish?s frequency was 947.456 Hz. This shows us that after a prolonged exposure to a similar frequency, the Apteronotus albifrons gradually returns towards its original frequency. This response may be attributed to the anti-social nature of the fish.
