Male Specific Neurons In Flies Essay -- Biology Fly

Have you watched a vaporize ensue another take flight all around the room and ever interrogate how they manage to always be so belt up together scour though the prey is trying its best to get away? Well, well-nigh scientists wondered. They were intrigued with this mating chase of the masculine fly after the young-bearing(prenominal) fly. You could feel out that the female was trying to play hard to get while the male lustily engages the pursuit.The male nearly always gets his prey. However, if the female fly tried to chase the male, she would have no such luck. This is due to the inner dimorphism of the fly. The male fly has a superior visual system to the female which he can use to locate and hold back the female fly in flight however, the female fly does not have this advantage. The male-specific neurons that reassure the flys superior visual system are complicated and intricate.The history butt the study of the flys neurons begins with a 19th Century scientist by the name of Cajal. He studied neural systems and was the first to isolate nerve cells near the appear of the brain. His work led to a greater study of neurobiology and the passion for attempting to realise the workings of the nervous system. However, real progress in this field did not culminate until Land and Collett established a remarkable theoretical pretense of the two part visual system of the flys brain.This model was incredibly close to the actual structure and function of the male flys visual system. The structure of the males eyeball are even disparate to the females. When looking at the two ramp by side, one can readily see the differences. Even these outmost physical differences attribute to the males superiority with his binocular vision and the ability to take note a charge continually in his... ...y will compensate, yaw, pitch, and hug, to return the target image into the area of male specific neurons. This behavior is found totally in male flies, and while f emale flies are attracted to move back and forth objects as males are, they do not use have a different system to control yaw torque as males do. The males employ a position- independent system of bring in using yaw adjustments, relying on direction. This allows the males to intercept a target or change direction in tracking without overshooting the target. Females are unable to do this. The males also use pitch and thrust to pursue other flies. The position of the target in the mid-sagittal plane drives the pitch, establish on the elevation of the targets image. Thrust relates to the distance between the pursuer and the target. The descent between target range and velocity is shown to be male-specific behavior.
