Happy Valentine’s Day!

Happy Valentine’s Day everyone! Here’s a brief look at some of the many neurotransmitters involved in the feeling of love.

  • Dopamine

Dopamine is associated with feelings of pleasure & satisfaction. It is also associated with addiction, movement, and motivation. The feelings of satisfaction caused by dopamine can become desired, and to satisfy this the person will repeat behaviours that lead to release of dopamine. These behaviours can be natural, as with eating and sex, or unnatural, as with drug addiction.

  • Serotonin

Serotonin is thought to be a contributor to feelings of well-being and happiness. It regulates the sleep cycle along with melatonin, and also regulates intestinal movements. Low levels of serotonin have been linked to depression, anxiety, and some mental disorders. Antidepressants work by increasing serotonin levels. Exercise and light levels can also both have positive effects on the levels of serotonin.

  • Adrenaline

Adrenaline, also known as epinephrine, is a hormone produced in high stress or exciting situations. It stimulates increased heart rate, contracts blood vessels, and dilates airways, to increase blood flow to the muscles & oxygen to the lungs. This leads to a physical boost, and heightened awareness. It contributes to the thrill of being in love.

Researchers have discovered a much faster way to learn new skills
How to level up twice as quickly.

“For skills to improve, we must update an existing memory with new information,” the researchers conclude. If you practice the exact same thing the exact same way every time, you’re not layering much new knowledge over what you already know.

Most animals have smooth brains. The brains of humans (and a handful of animals we consider pretty intelligent – dolphins, chimps, elephants, pigs) start out smooth in the early days of gestation and get more and more wrinkled through infancy.

A wrinkled brain makes sense - folding means you can have a really big cortex but the different parts of the brain won’t be as far apart. But how do brains become wrinkled? Is it programmed somehow - does some genetic code determine the pattern of folds?

A new study from Harvard says no - its just simple physics. They created a 3D model of a smooth fetal brain and coated it with an elastomer gel “cortex.” When they immersed this brain in a special solution, the gel swelled, mimicking brain growth.

Lo and behold, the brain began to buckle, creating folds similar to size, shape and location of a real brain.

Avoid some of the Main Brain Damaging Habits

1. No Breakfast – People who don’t eat breakfast have lower blood sugar levels. This can lead to an insufficient supply of nutrients to the brain (and to underperformance in terms of thinking, processing , retrieval and memory skills).
2. Overreacting – This can flood the brain with chemical which interferes with clear thinking, logical analysis and memory.
3. Smoking – This can cause a shrinkage in the brain, and possibly lead to Alzheimer’s disease.
4. High Sugar Consumption – Consuming too much sugar interferes with the absorption of proteins and nutrients. These are essential for healthy brain development.
5. Air Pollution – The brain is the largest oxygen consumer in our body. Inhaling polluted air decreases the supply of oxygen to the brain. Again, this can reduce and interfere with the brain’s healthy functioning.
6. Sleep Deprivation – Sleep allows our brain to rest and rejuvenate itself. Long term sleep deprivation accelerates the death of brain cells. It interferes with putting down new memory traces, effective problem solving and memory retention.
7. Exercising your Brain in Times of Illness – Working or studying during times of sickness can lead to a ineffective thinking, poor processing, and to poor memory and retention.
8. Lack of Stimulation – Thinking is the best way to train our brain. Lack of stimulation can prevent new neural pathways from forming. It can also prevent us from reaching our potential in terms of creative thinking and analytical thinking.

New brain implant could move paralyzed limbs with just a thought

It’s called a stent-electrode recording array, and it has been used for the last few years for neurological conditions, according to a paper by University of Melbourne researchers. But a 39-person team from 16 of the university’s departments think it could be used to make people walk again. But wait it gets even better.

Entire Rabbit Brain Successfully Frozen and Revived For First Time

Researchers from 21st Century Medicine (21CM) have for the first time successfully frozen and recovered an entire mammalian brain. This remarkable feat earned researchers the Small Mammal Brain Preservation Prize, awarded by the Brain Preservation Foundation.

The cryogenically preserved brain belonged to a rabbit, and using an innovative technique called Aldehyde-stabilized cryopreservation (ASC), researchers were able to return the animal’s brain to near-perfect condition.  

“Using a combination of ultrafast chemical fixation and cryogenic storage, it is the first demonstration that near­ perfect, long-term structural preservation of an intact mammalian brain is achievable,” the Brain Preservation Foundation wrote in a news release.

Their study was recently published in the journal Cryobiology.

There’s great news for people who prefer real books over e-readers

Naomi Baron, American University linguistics professor and author conducted a series of cross-cultural studies with her colleagues asking college students around the world if they preferred electronic or hardcopy books. A whopping 92% said they preferred the latter. Reading physical books affects the brain differently than reading digitally.
