Hidden Brain - Making the world sparkle again.

Habituation and the hedonic treadmill

Look again - the power of noticing what was always there.

Dishabituation - a break from your routine makes you see your routine anew. Julie Roberts "resparkles" time with her family by returning after shooting a movie. 

Changing your environment primes your brain for taking in information differently and sparking creativity. But the effect only lasts 6 minutes. 

Experiences retain their intrigue far longer than material items. Experiences are recollected over and over, and you habituate slower. 

Giving is much more satisfying than receiving. The rate of habituation of feeling happy is much faster for things you get for yourself. 

Variety enhances psychological experiences. Variety prevents habituation. Variety by definition means there's change, so you can't habituate to it. 

Shorter vacations may be better - vacations peak in happiness at 43 hours. A few short vacations will be more exciting than longer ones. 

People who are asked say they prefer hearing a favorite song without interruption. But when tested, they enjoyed it now if it was interrupted. Same with massage. 

Conversely, distasteful experiences are best done without breaks, so you don't have to re-enter the habituation to the bad. 

People who have had depression returned to neutral emotion slower after bad news. 

Disastrous accidents often happen near the very end of an undertaking. The workers habituate to the danger and take less precautions at the end of the project.

Who was Kilroy?

Interesting history. 

Just Who Was Kilroy?

It is not clear just where the viral "Kilroy Was Here" tradition got started. Soon after WWII ended, the American Transit Association ran a contest to track down its origins. Scores stepped forward, to claim that they had been the originators. Ever since, there has been plenty of research on Kilroy. The likeliest theory traces the meme to James J. Kilroy, a Fore River Shipyard in Braintree, Massachusetts, inspector. That Kilroy supervised the work of riveters who were paid by the number of rivets installed. After they noted that number down, inspectors put chalk marks on the work done. However, some unscrupulous riveters erased the mark, in order to get paid twice for the same work. To avoid that, Kilroy wrote "Kilroy was here" in harder-to-erase crayon.

Kilroy's crayon marks would normally have been painted over. Wartime was hectic, however, and in WWII, that didn't always happen. Thousands of GIs came across "Kilroy was here" on ships built at Fore River Shipyard. None of them knew who Kilroy was, but they wondered, and that minor mystery birthed a viral meme tradition. The hardest to reach ship locations were the likeliest to go unpainted. The presence of the crayoned phrase in those spots enhanced Kilroy's reputation for getting into impossible-to-reach places. When they got off their ships, many servicemen continued the gag about the mysterious Kilroy. They ran with it, and tagged every available surface to let the world know that Kilroy had been there. Somebody at some point added an easy-to-imitate drawing of a big-nosed cartoon character to the gag. The phrase and drawing combination took Kilroy from a widespread meme to major viral history.

Reserve rides ahead of time at Disney world

Just in time before we have grandchildren, Disney is introducing reservations a week ahead for theme park rides, if you're staying at one of their hotels. 

"guests will be able to reserve rides and shows ahead of time...Guests staying at Disney World's resort hotels can make selections up to seven days in advance, all at once, for up to 14 days of their stay." 

Submarine diving and surfacing mechanics

https://youtu.be/XFJnWp1tAdU?si=nNdTrFYJ-p48quV-

8:51 A submarine's buoyancy is affected by the temperature and salinity of the water. Melting arctic ice gives areas of low salinity that have to be measured and accounted for. 

During surfacing, orientation in 3 dimensions is very critical, so that (23:20) "just the weight of one person walking from forward to aft of the ship will upset the balance," so an order is given to not walk around, just as they're surfacing. 

21:28 If the submarine has any momentum from a sideways current when surfacing through ice, and if the vertical "punch" through the ice isn't forceful enough, the submarine could violently roll rather than punch through, damaging tail planes and prop.

Chickadee - bird brains. The genius of birds.

Chris Templeton and his colleagues have found that chickadees use their calls like language, complete with syntax that can...convey their location or...news of a tasty treat... warn of predators - both the type and magnitude of the threat. A soft, high-pitched call signals a threat on the wing...the signature chickadee-dee-dee flags a stationary predator...the number of those skipping-stone "dees" indicates the predator's size. 

p.40, 'The Genius of Birds,' Jennifer Ackerman.

Mountain chickadees that live in the colder, snowier conditions of higher elevations have bigger hippocampi [the brain region vital for spatial learning and memory] than their lower-elevation peers... This makes sense. At higher elevations, where it stays cold longer, birds must store seeds and remember where they put them. Recovering caches is not so critical in milder climates, where food is available year-round. p. 53, 'The Genius of Birds,' Jennifer Ackerman.

War = escalating reciprocal retributions

Gazans Speak of Devastation After Israeli Hostage Rescue https://www.nytimes.com/live/2024/06/09/world/israel-gaza-war-hamas?smid=nytcore-android-share

War is so often a story of escalating reciprocal retributions, and this quotation says it all: 

"he saw the street covered in blood and bodies. Gazans there were cursing not just Israel, but Hamas as well, he said, blaming them for bringing this disaster upon them." 

This is so senseless to me. 

Electrical shocks to tongue to treat tinnitus

"The leading explanation for this link is that the loss of input from the ears causes the brain to compensate by becoming more sensitive — sometimes called the central gain theory."

"the nerve fibres that carry signals from hair cells to the brain... are at least three different types, letting us process sounds at different volumes: quiet, intermediate and loud. The ones that process loud sounds are most susceptible to damage."

"People who have [tinnitus] but have good hearing, according to the standard hearing test known as an audiogram, have long been a stumbling block for the central gain theory. However, if they had damage solely to their loud nerve fibres, this wouldn't show up as hearing loss in an audiogram, which only measures the quietest sounds"

"Niliksha Gunewardene at the Bionics Institute in Melbourne...recently shown that in animals, an injection of neurotrophin-3-loaded nanoparticles into the ear releases neurotrophin-3 in the inner ears of mice, which leads to synapse growth."

"the cochlear nucleus also has inputs from other parts of the body, including touch neurons from the face, jaw and neck, which may be to suppress sounds caused by movements of the body, such as chewing...Neuromod Devices [have produced a] device called Lenire, which... delivers electrical stimulation to the tongue at the same time as the person listens to sounds through headphones."

Birds at Risk of Extinction Due to Climate Change

I didn't know it was this dire: 

"a grim picture: a steady decline of nearly three billion North American birds since 1970, primarily as a result of human activities. Climate change will further exacerbate the challenges birds are already facing from human activity.  

In 2014, Audubon published its first Birds and Climate Change Report. The study showed that more than half of the bird species in North America could lose at least half of their current ranges by 2080 due to rising temperatures." 

-audobon.org

"Cats have contributed to the extinction of 63 species of birds, mammals, and reptiles in the wild...In the United States alone, outdoor cats kill approximately 2.4 billion birds every year."
