Sleep Physiology

Sleep is a condition of reduced muscle movement in the body. Awareness about the surroundings is reduced at the time of sleep. The body stays mildly responsive or non-responsive to external stimuli. The sleep-wake cycle is controlled by the circadian rhythm that produces a resting phase for the body.

After recovering from his TTX poisoning, Dr. Marshall Westwood decided to take a vacation. An avid birder, he decided to go to Papua New Guinea with Bill Whitlatch, an ornithologist friend of his from Montana Technical Institute. Three days into their trip, Bill netted a bird with an orange body and black wings and head for closer study. Dr. Westwood was very curious and asked Bill if he could have a closer look at the bird. After handling the bird and later touching his mouth with his hand, Dr. Westwood noticed that his fingers and lips were going numb. His mind immediately flashed back to the disastrous trip to Indonesia and he began to panic. Luckily, the symptoms faded before they progressed into anything more serious. His friend Bill used a key to identify the animal as a ‘pitohui.’ The pitohui are small, social songbirds that live in Papua New Guinea. They are generally about 23 centimeters long with strong legs and a powerful beak. Their encounter was the first time anyone had…

In an investigation of fruit fly behavior, an enclosed choice chamber was used to test whether the spatial distribution of flies is affected by the presence of a substance placed at one end of the chamber. To test the flies’ preference for different substances, 50 flies were introduced into the choice chamber. A piece of ripe banana was placed at the end of the chamber on side A and a piece of unripe banana was placed at the end of the chamber on side B (Figure 1). The positions of the flies were observed and recorded at the start of the experiment and after 10 minutes (Table 1).
