CRICKETS AND THEIR REACTION TO DIFFERENT STIMULI, LIGHT, SOUND, AND TOUCH

Introduction

According to Dorothea Kohstall-Schnell and Heribert Gras, Nicklaus, R found in his study most insects have fine hairs and/ or other structures for detecting movement such as wind and sound. (Activity of Giant Interneurones and other Wind-Sensitive Elements of the Terminal Ganglion in the Walking Cricket. Kohstall-Schnell, D. Gras, H. 1994).The cricket is equipped with these hair sensory structures. According to Dorothea Kohstall-Schnell and Heribert Gras, Palka, J. and Olberg, R found these structures trigger sensory cells and the message then passes through neurons to reach the terminal ganglion. (Activity of Giant Interneurones and other Wind-Sensitive Elements of the Terminal Ganglion in the Walking Cricket. Kohstall-Schnell, D. Gras, H. 1994). Dingle and Fox (1966) recently demonstrated that light also has an effect on cricket’s brain responses. Crickets are an easy invertebrate to test; they are mobile and are known for jumping and their mating noises. The crickets will react to different stimuli, light, sound, and motion, when placed on ice. The cricket’s movement will gradually increase as another stimulus is added on, making the three stimuli the highest amount of movement. With the crickets being cooled down they will be less mobile, but the stimuli will still have an effect on them. This experiment was chosen because crickets are easily accessed, as well as the rest of the materials used in this lab. The experiment started out being a simple hot vs. cold experiment with crickets, then it was given stimuli to make the lab more thought-provoking.
