Visible spectrum. Solar spectrum.
Dark patches are due to absorption by gases in the Sun. The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. The_sound_a_human_makes_by_logan_bier_sharelit.pdf. SSC: Key Concepts. In developing our workshops on sustainability (for example, MASH), SSC has emphasized connections at many levels: with each other, with what sustainability means, and to a larger context.
We have found information about the brain's anatomy and function offers an explanation of why these connections are so critical to our understanding as well as how we present them. Current research on the human brain by Dr. Paul MacLean, evolutionary neuroanatomist and senior research scientist at National Institutes of Mental Health, has revealed that the human brain consists of three parts which have distinct, but interrelated, functions. SSC: Key Concepts. Beta wave. Beta wave, or beta rhythm, is the term used to designate the frequency range of human brain activity between 12.5 and 30 Hz (12.5 to 30 transitions or cycles per second).
Beta waves are split into three sections: Low Beta Waves (12.5–16 Hz, "Beta 1 power"); Beta Waves (16.5–20 Hz, "Beta 2 power"); and High Beta Waves (20.5–28 Hz, "Beta 3 power"). Beta states are the states associated with normal waking consciousness. Function Low amplitude beta waves with multiple and varying frequencies are often associated with active, busy, or anxious thinking and active concentration. See also Neural oscillation. Linguistics 001. Over the past century or so, we've learned a lot about the mental processes of producing, perceiving and learning language.

When we diminish the brain rythm to alpha, we put ourselves in the ideal condition to learn new information, keep fact, data, perform elaborate tasks, learn languages, analyse complex situations. Beta wave. Beta Brain Waves Infographic - Transparent Corp. One of the most well researched and documented uses for brainwave stimulation is as an aid for those who have trouble focusing- particularly those diagnosed with ADD/ADHD.
A major study on this benefit of beta stimulation was conducted in 1996 by Dr. Alpha wave. Alpha waves are neural oscillations in the frequency range of 7.5–12.5 Hz arising from synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans.
They are also called Berger's wave in memory of the founder of EEG. Alpha waves are one type of brain waves detected either by electroencephalography (EEG) or magnetoencephalography (MEG) and predominantly originate from the occipital lobe during wakeful relaxation with closed eyes. Brainwave States. The audio tracks developed by the Immrama Institute use a specific type of brainwave technology to guide your brain into various states.
To recognize why this detail is significant, it’s important to understand how your brain contributes to your state of mind and level of consciousness. There are several different brainwave states. Your brain cycles through each of these brainwave states many times throughout the day and night. Alpha Brain Waves Infographic - Transparent Corp.
In March of 2006, a paper was published in BMC Neuroscience which outlined the effects that alpha brain wave stimulation had on a difficult memory task, showing very promising results.
The authors of this paper explain that their study was based on research correlating 10 Hz alpha wave rhythms with memory performance, and additional studies showing that alpha activity declines along with memory due to aging. During the test, the patients were presented with three letter words, and were given brief bursts of alpha photic stimulation, at various frequencies, as the words were presented. Later, the participants recognition of the words was tested, without any stimulation involved. The result was that the older participants who received photic stimulation around 10.2 Hz were able to perform just as well on the test as the much younger participants. Delta Brain Waves Infographic - Transparent Corp. This 2005 study was conducted to explore whether brain stimulation could be useful in reducing preoperative anxiety in patients, while still allowing them to be "street ready" after the operation- meaning their mobility and functionality would not be hindered. 108 patients who were scheduled to undergo general anaesthesia for elective surgery were recruited for this controlled study.
About an hour before their operation, the subjects were asked to complete a State-Trait Anxiety Inventory (STAI) questionnaire. The STAI is a well validated and widely used test for measuring subjective feelings of anxiety. Scores for the STAI range from 20 to 80, with a higher score corresponding to higher anxiety levels. Subjects were separated into one of three groups. At the end of the 30 minutes, participants completed the STAI questionnaire for a second time.

Keep in mind that the most fluent phrase we ever hear Tarman say in Return of the Living Dead is "Braaaaaains! " Tarman goes on a short lived speaking tour. Linguistics 001. Understanding Brainwaves to Expand our Consciousness. The human brain is a complex entity constantly at work, sending electrical signals, communicating, building new neural connections and so on. This electrical activity generated by the brain, also known as brainwaves, reflect our state of mind. Reality is not based on outside influences but is an internal process based on our thoughts, perception and emotions. Understanding Brainwaves to Expand our Consciousness. Traumatic Brain Injury Resource Guide - Frontal Lobes.
The frontal lobes are considered our emotional control center and home to our personality. There is no other part of the brain where lesions can cause such a wide variety of symptoms (Kolb & Wishaw, 1990). The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior. The frontal lobes are extremely vulnerable to injury due to their location at the front of the cranium, proximity to the sphenoid wing and their large size. MRI studies have shown that the frontal area is the most common region of injury following mild to moderate traumatic brain injury (Levin et al., 1987).
There are important asymmetrical differences in the frontal lobes.
