Rapid eye movement sleep

The four main evolutionary theories can be used to explain the function of sleep which consist of energy conservation, food requirements, predator avoidance and Meddis’ “waste of time” hypothesis. These theories attempt to explain sleep as an adaptive response which increases the chances of survival. Sleep can be used to conserve energy over long periods of time as metabolism and body temperature decreases. This can be observed in sleeping animals especially in those hibernating during the…

Q10. There are five different stages of sleep that a person goes through when they are sleeping. These stages are differentiated by the theta activity (slow wave sleep) that takes place in each stage. The first stage that takes place involved theta activity which means the firing of neurons in the neocortex has begun. During this level of sleep there is an EGG level of 3.5-7.5 HZ. The EEG level is the electrical activity that takes place within the brain, it is recorded through electrodes that…

The collars use were neck loop transmitters and body loop transmitters and were 5% or less of the quail’s body mass. Some birds were released in pairs, while other birds were released alone. Some birds were also kept overnight and released in a different location within a 24-hour period. All quail died within 16 days of the study. Factors contributing to quail fatality were predation, stress, and poor habitat condition. Montezuma Quail rely on cover to escape from predators, and poor habitat…

Delta waves (0.5-4Hz) are a characteristic of deep sleep and are generally not present during meditation or relaxation. Theta waves (4-8Hz) are strongest in the frontal and middle parts of the brain during meditation and most likely show the relaxed attention that arises as we focus on our inner experiences. Frequent Theta waves are more likely to occur in highly experienced meditation practitioners. Alpha waves (8-13Hz) are present during relaxation, daydreaming and light meditation and…

help people to see their sleep habits. After, they analyze their sleep habits, maybe they can change their ways. Case Study is an in-depth observation of one participant (Pastorino, E. & Doyle-Portillo, S. 2013). The benefits of a case study is that it keep up with document and report. Terese Analysis Terese sleep cycle is not in routine, its everywhere. Terese notices that she was not getting enough sleep but she was getting enough. Terese noticed that you do not sleep much on the weekdays,…

consequence of ventral brainstem damage as a result of vascular or traumatic lesions disconnecting corticospinal and corticobulbar tracts bilaterally” (Pistoia et al., 2016, p. 32). Locked-in syndrome causes complete paralysis with the exception of eye movement, however the patient is completely conscious and aware of surroundings (Pistoia et al., 2016). According to Pistoia et al., (2016), due to the disconnection of the cortex and spinal cord in…

Although the flytrap cannot literally consumer a full human body, I took artistic liberty in exaggerating the flytraps size in order to capture the viewer’s eye and interest the viewer in the flytrap’s actual abilities. I also drew a glow around the flytrap to highlight its abilities to draw in prey. Throughout this sketch, I felt as though I was creating an equal medium between my two original ideas, so I…

The Venus flytrap is a plant native to wetlands on the East Coast of the United States in North Carolina and South Carolina. The scientific name for the Venus Fly Trap is Dionaea Muscipula. It’s one of the most fascinating plants to have ever existed due to its omnivorous nature. Darwin noted, “‘I care more for Drosera than the origin of species ... it is a wonderful plant, or rather a most sagacious animal. I will stick up for Drosera to the day of my death.” The Venus flytrap reproduces by…

As many know, a Venus flytrap (or Dionaea muscipula seed) achieves its energy not only through photosynthesis, but through devouring its prey (dragon flies, mosquitoes, etc.). The Venus flytrap’s “mouth” (trapping mechanism) is very rough and is always green. This part of the organism’s body is also covered with a fragrant nectar that attracts its prey towards it. When the prey reaches the Venus flytrap, it begins to feed off of the nectar. Once touching its leaf, the prey sets off a twenty…

Dziegielewski and Wolfe used an ABA single subject design in their study. The subject, a 24 year-old Caucasian female who was referred to as Brandy, took a pretest of the Self-Esteem Rating Scale (SERS) developed by Nugent and Thomas (1993) and the Body Image Avoidance Questionnaire (BIAQ) by Rosen, Srebnik, Saltzberg, and Wendt (1991) before the baseline data was collected. Negative scores on the SERS, which ranged from -120 to +120, meant low self-esteem and the higher the scores on the BIAQ,…
