Male Specific Neurons In Flies Essay -- Biology Fly

Have you watched a fly chase a nonher fly all around the style and ever wonder how they manage to always be so penny-pinching to extendher even though the feed is trying its best to shake up away? Well, some scientists wondered. They were intrigued with this mating chase of the male fly later the female fly. You could say 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 pick out no much(prenominal) luck. This is due to the sexual dimorphism of the fly. The male fly has a superior optical system to the female which he can design to locate and knock the female fly in flight however, the female fly does not have this advantage. The male-specific neurons that control the flys superior optic system are compound and intricate.The history behind the convey of the flys neurons begins with a 19th Century scientist by the name of Cajal. He stu died neural systems and was the first to isolate affectionateness cells near the surface of the brain. His work led to a greater study of neurobiology and the passion for attempting to understand the workings of the nervous system. However, real progress in this field did not culminate until Land and Collett established a unique theoretical puzzle 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 eyes are even different to the females. When looking at the two side by side, one can readily think the differences. Even these outer physical differences attribute to the males superiority with his binocular fantasy and the ability to keep a target continually in his... ...y go out compensate, gawk, pitch, and thrust, to return the target image into the area of male specific neurons. This deportment is found only in male go, and while female flies are attr acted to flickering 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 tracking using yaw adjustments, relying on way. 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, based on the elevation of the targets image. Thrust relates to the distance amid the pursuer and the target. The relationship between target range and velocity is shown to be male-specific behavior.
