Sleeping is a natural part of our daily life. It is a behavior that is displayed every day and is necessary for us to function. To be able to rest efficiently an animal, be it a human or another mammal, needs to fall asleep in a matter of seconds or minutes; but since a sleeping animals are more vulnerable to predation, it also needs to wake easily in case of threat. Those requirements show how well regulated the sleep-wake regulation has to be. Historically, sleep studies have been done by a combination of electroencephalography (EEG) and electromyography (EMG), the signals obtained allowed to define three sleep/wake stages(REF). The first one is displayed by awake animal, the EEG show a high frequency activity (beta waves) and the EMG signal is high, reflecting the motor activity of the animal. The second and third stages are present in sleeping animals, called respectively non-rapid eye movement sleep (NREM sleep) and rapid eye movement sleep (REM sleep). They are characterized by a slow EEG activity (delta waves) during the NREM sleep and a high frequency activity (theta waves) coupled with a…
The popular science article “You May Be Able to Train Your Brain to Be Fearless” published by The Huffington Post discusses the study “Limbic Activity Modulation Guided by Functional Magnetic Resonance Imaging–Inspired Electroencephalography Improves Implicit Emotion Regulation” conducted by Dr. Talma Hendler. I find that the pop science article doesn’t portray the information correctly. It fails to include terminology and key results; specifically, the downsides of the study. The article’s sole…
While on this planet we live on, we need to find things to occupy ourselves in our spare time. Some common things people do are athletics, playing video games, or simply catching up on missed sleep by napping. Some people branch out to poetry – a boring subject if taking only a superficial point of view. But certain individuals take it further, and it becomes their occupation or their profession. They find that skillful poetry can be used as an outlet to articulate their ideas and feelings with…
Following the introduction of the brain-disease model of addiction, proponents and opponents have emerged to argue for or against a neurocentric view of addiction and the importance of brain circuitry in treating addiction. The following discussion will discuss the societal pros and cons of labeling addiction a brain disease and evaluate whether brain circuitry is necessary for the treatment of addiction in order to illuminate the benefits and drawbacks of the brain-disease model for…
As previously mentioned, in addition to the structural priming paradigm, the proposed study will make use of the measurement of event-related potentials via EEG. In order to measure the potentials accurately, there needs to be a starting point for which to begin the EEG measurements. Peter Hagoort (2008) suggests that the EEG measurement for an experiment measuring the P600, such as the proposed study, should begin at the final word of the sentence. However, I disagree with this idea, and side…
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…
The pillow protector is considered as one of the most important bedding essential. The pillows are used in everyday life and the users it directly against the skin for at least 6-8 hours during the night. While the head is resting on the pillow the user is breathing whatever has been absorbed by the pillows. The pillows are also expensive and it is important to make sure that the pillows are kept clean because dirty pillows are not good for the health of the users. Make sure that the pillows are…
Parents all over the world love their children. Mothers will always be protective and fathers will always be the one cheering from the sidelines at a game. They will strive to see their child grow up to be successful in the world. Little Johnny will look up to his father and try hard to impress him, and Little Shelby will do the same thing with her mother, or vice versa. The parental figures in society expresses a type of love that will bug the child from time to time. Johnny will grow up…
There are few things I remember. I was painting, felt dizzy, the next thing I remember is talking to the paramedic as I was lying on the floor. I remember being in the hospital, but not going to the hospital. I remember talking to my friends in the hospital, then I remember talking to the doctors, them telling me I had had three seizures in the past two days. Three weeks later, I remember waking up on a Wednesday with a killer headache. The worst headache I had ever had, but I don’t remember how…
Psychology – Sleep Assignment Title: Snoozzzze before you losssse What is Sleep? Sleep is described as a non-waking state of consciousness that is characterised by general unresponsiveness to the environment and physical immobility. Sleep is when the nervous system of your body is inactive and the muscles are relaxed. Why do we sleep when we do? Humans tend to sleep 5-8 hours every night, and to do so in a pattern tied to the 24-hour light-darkness cycle. This cycle is called a circadian rhythm…
