The Biology Project. How to Wake Up Feeling Totally Alert. Your alarm goes off at 5am, and you immediately get out of bed without a second thought. As you orient yourself to the waking world, you can barely detect any lingering grogginess, even if you look for it. You stand up and stretch, feeling totally alert, fully conscious, and eager to start your day. The thought of going back to bed to get some extra sleep seems completely alien to you. It feels great to be up early, and you know you’ll put those early morning hours to good use. Maintaining this habit is easy for you. If this scenario closely matches your current daily reality, you can stop reading now. Waking up groggy During my teen years and well into my 20s, I would usually wake up feeling very groggy in the morning.
I wasn’t much good during those morning hours. From grog monster to early riser Fast forward to the present, and I’m a habitual early riser. If you’re so groggy you can’t get up before drifting back to sleep, you don’t need a new alarm clock. Experiment. Fix your diet. Cool Science. Better information. Better health. Science.

The things that make me want to get up in the morning are things that make normal people lose interest in the conversation, or giggle. These are things like lucid dreaming, artificial intelligence, utopian movements, and Esperanto. Be that as it may, I'm mostly fine with boring the normals and living in the Vibrant True World of Beauty with its other full-on dork denizens.
Amazingly, I've found that Esperantists seem to be anarcho-Taoists, that AI researchers tend to have experimented with lucid dreaming, and that other secret threads hold the seemingly disparate interests of Dorks Like Me together. I have countrymen. Just not yet my country. The other thing that holds my kinsmen together, though, is an unfortunate thing: they are all asses.
In case you're wondering if my sermon is directed to you, there are some common tropes in our oft-reenacted social suicide: We call someone's beliefs "idiotic.

Muscular System Anatomy, Diagram & Function. Without muscle, humans could not live. The primary job of muscle is to move the bones of the skeleton, but muscles also enable the heart to beat and constitute the walls of other important hollow organs. There are three types of muscle tissue: Skeletal muscle: This type of muscle creates movement in the body. There are more than 600 skeletal muscles, and they makes up about 40 percent of a person’s body weight. Muscle movement happens when neurological signals produce electrical changes in muscle cells. Muscle pain is a common issue that can signal numerous problems, even if it’s something as simple as overuse. Muscle pain Sprains and strains Bruising Cramping Myopathy Muscular dystrophy Parkinson’s disease Fibromyalgia Multiple sclerosis Proper nutrition and exercise is important to keeping all muscles healthy, whether they are cardiac, smooth, or skeletal.

Neurotransmitters-Serotonin: An Overview - Associated Content - A neurotransmitter is a chemical that is released from neurons in order for signals to be passed from one neuron to another.
These chemicals are stored in the terminal buttons of a neuron and are released into the synapse between two neurons in order to carry the signal from one to the other (Davis, S. & Palladino, J. (2007). The neurons terminal buttons do not touch each other but get near the dendrites of the neighboring neurons and pass the neurotransmitter signal to the next neuron. A neuron is electrically charged and when a neuron releases this energy this is called exciting the neuron. When enough energy is released to the dendrites of the neuron, biochemicals or neurotransmitters are released to the surrounding neurons. Lack of communication between neurons can lead to a number of physical and mental disorders such as arousal problems, depression, Alzheimer's disease, seizure disorders and epileptic seizures.

& Palladino, J. (2007). UpperSaddle: New Jersey. Feelings of Knowing : The Frontal Cortex. Clive Thompson has a wonderful article in the NY Times Magazine on Watson, the supercomputer programmed to excel at Jeopardy. Thompson delves into the clever heuristics used to generate singular answers to ambiguous questions. (Watson relies on massive amounts of parallel processing, so that “he” is running thousands of Google searches simultaneously.)
While Watson’s performance is certainly impressive, I thought the most interesting part of the story involved the failings of the machine. It’s easy to rhapsodize about the ever escalating speed of microchips, but it turns out that Watson is often too slow at ringing the buzzer: In more than 20 games I witnessed between Watson and former “Jeopardy!” Players, humans frequently beat Watson to the buzzer. This anecdote highlights one of the most impressive talents of the human mind. What’s interesting about this mental hiccup is that, even though the mind can’t remember the information, it’s convinced that it knows it.
