Science shows yoga may protect your brain in old age

Scientists in Brazil have imaged elderly female yoga practitioners’ brains and found they have greater cortical thickness in the left prefrontal cortex, in brain areas associated with cognitive functions like attention and memory. The results suggest that yoga could be a way to protect against cognitive decline in old age.
As we age, the structure and functionality of our brains change and this often leads to cognitive decline, including impaired attention or memory. One such change in the brain involves the cerebral cortex becoming thinner, which scientists have shown is correlated with cognitive decline. So, how can we slow or reverse these changes?
You might think medication would be required, but surprisingly, the answer could lie in contemplative practices like yoga. Yoga practitioners consciously maintain postures, and perform breathing exercises and meditation.
“In the same way as muscles, the brain develops through training,” explains Elisa Kozasa of Hospital Israelita Albert Einstein in São Paulo, Brazil, a researcher involved in the study, which was recently published in Frontiers in Aging Neuroscience. “Like any contemplative practice, yoga has a cognitive component in which attention and concentration are important.”
Previous studies have suggested that yoga can have greater health benefits than similar aerobic exercises, and yoga practitioners have shown improved awareness, attention and memory. Older adults with mild cognitive impairment have also shown improvements after a short yoga training program.
But can practicing yoga over several years significantly shape your brain and if so, could it offset some of the changes that happen in the aging brain? The research team wanted to see if elderly long-term yoga practitioners had any differences in terms of brain structure compared with healthy elderly people who had never practiced yoga.
They recruited 21 female yoga practitioners (also known as yoginis) who had practiced yoga at least twice a week for a minimum of 8 years, although the group had an average of nearly 15 years of yoga practice. The researchers compared the yoginis with another group of 21 healthy women, who had never practiced yoga, meditation or any other contemplative practices, but who were well-matched to the yoginis in terms of their age (all the participants were 60 or over) and levels of physical activity. For more consistent results, the researchers only recruited women, and the participants completed surveys to see if there were any other factors at work that could affect brain structure, such as depression or level of formal education.
The researchers scanned the participants’ brains using magnetic resonance imaging to see if there were any differences in brain structure. “We found greater thickness in the left prefrontal cortex in the yoginis, in brain regions associated with cognitive functions such as attention and memory,” says Rui Afonso, another researcher involved in the study. As the groups were well-matched in terms of other factors that can change brain structure, such as education and levels of depression, yoga practice appears to underlie the yoginis’ different brain structure.

The results suggest that practicing yoga in the long-term can change the structure of your brain and could protect against cognitive decline in old age. However, the team plan to carry out more studies to see if these brain changes result in enhanced cognitive performance in elderly yoginis.
Another possibility is that people with these brain features are more likely to be attracted to yoga. “We have compared experienced yoginis with non-practitioners, so we do not know if the yoginis already had these differences before they started yoga,” explains Afonso. “This can only be confirmed by studying people for a few years from the time they start yoga.”

June 2015     Nikon Reviews   Nikon Lenses   All Reviews

Ideal Uses: Super-sharp normal lens for manual-focus and FX cameras in good light. Photography of fish in tanks. Nikon's least expensive used macro lens; and it will work on even the cheapest cameras like the D40 but you will have to guess at exposure.
Not for: For serious macro use, 105mm or 200mm lenses are much better ideas because they give you enough room between you and your subject. As a manual focus lens, I wouldn't use this for sports, kids or action since it's too hard to track focus by hand.
Ergonomics: (manual focus)

Introduction       top
Compatibility    History    Production    Pricing
Nikon uses the word "Micro" to mean the same thing as "macro." I'll use these words interchangeably.
The Nikon Micro-NIKKOR 55mm f/3.5 is an excellent manual-focus lens. It works perfectly on every manual-focus Nikon camera, and also works great on all better digital Nikons, especially the D3XD700 and other FX cameras. It won't meter with the cheaper DX digital or AF cameras like the D90; for these cameras, guess and use the LCD, or use the Gossen Digisix meter and hot-shoe adapter.
For manual focus cameras, the newer f/2.8 AI-s version is still made today, and used f/2.8 versions cost very little more. This f/3.5 is a great lens, but if I had my choice, I'd get the f/2.8. I only bought this one to archive here; I already have two f/2.8 AI-s 55mm lenses I bought new over the years.
For AF and digital cameras, I'd suggest getting the newest 60mm AFD instead. For the D40, you'll want the 60mm AF-S to have autofocus.
Even for manual focus cameras today, I'd suggest getting the 60mm AFD since it also will work perfectly on your AF cameras.
The optics of all of these lenses are superlative; it's the mechanics and ease of use with AF and digital cameras which varies.
Focus Scale, Nikon 55/3.5

Compatibility       back to intro     back to top
The manual-focus 55mm f/3.5 AI works great with most Nikon cameras, film and digital.
It works flawlessly with every manual focus Nikon ever made, from the F of 1959 through the FM3a and today's FM-10.
On the D3XD3D700D300D200D2 and F6, use the "Non-CPU Lens Data" menu option to set 55mm and f/3.5 to get full matrix metering, EXIF data and finder read-out of set aperture. It works great in aperture-preferred as well as manual modes on these cameras.
It works perfectly on every professional film camera (FF2F3F4F5F6), and adds Matrix metering on the FAF4 and F6.
The meters of cheaper digital (D80 and below) and cheaper film cameras (N80 and below) will not couple (or work at all) with this lens, so you'll be on your own guessing exposure using the rear LCD or an external meter, or get a tiny Gossen Digisix meter and hot shoe adapter to meter manually.
See Nikon Lens Compatibility for details on your camera. Read down the "AI, AI-s" column for this lens.
The earliest non-AI versions should be upgraded to AI, otherwise, they are compatible with much fewer cameras. If you have a non-AI lens, see Nikon Lens Compatibility and read down the "pre-AI" column.

History    back to intro     back to top
Nikon made this same optical design starting in 1961, and changed the cosmetics, mechanics and coatings as time progressed.
The version shown above is the newest AI version made from about 1975 - 1979.

Nikon first made the 55mm f/3.5 Micro for its rangefinder cameras.
God only knows how you focused or composed without through-the-lens viewing.
Nikon didn't make a lot of these; LEICA was the market leader in those days.

Nikon put the same optics from the rangefinder lens in an F (SLR) mount mount for its new Nikon F 35mm SLR.
THey made at least two different cosmetic versions of this SLR lens.
Nikon made about 100,000 of these early verisons.

Nikon changed the optics slighty to the version reviewed here. Nikon made several different cosmetic versions, both AI and non-AI with the same optics, both single and multi-coated.
THese versions are best iditfied by serial number, or more casually, by a rubber (not fluted aluminum) focus grip.
Nikon made about 500,000 of these later verisons; about 275,000 AI and 165,000 non-AI.

1979 - today
Nikon introduced the improved 55mm f/2.8 AI-s Micro-Nikkor which replaced this f/3.5 version.
This current f/2.8 version adds CRC, close-range-correction, for optimum performance at every distance.
Nikon has made about 600,000 of these — so far.

55mm f/2.8 AF, Nikon's first AF micro, used the same optics as the AI-s verison.
Nikon only made about 50,000 of these.

A completely new design, the 60mm f/2.8 AF comes out to replace the 55mm f/2.8 AF.
Nikon made about 150,000 of these non-D AF versions.

60mm f/2.8 AF-D, which is the same as the previous 60mm f/2.8 AF but adds the minor D feature.
Nikon made about 300,000 of the AF-D versions, or about 450,000 total 60mm f/2.8 AF — so far.

The newest version is the 60mm AF-S Micro, which replaces the 60mm AF-D Micro. The AF-S micro will not work on cameras older than about 1993, while all these other lenses are perfectly compatible with them.

Performance       top

Overall      back to Performance    back to top
The 55mm f/3.5 is a great lens. It just works, and always delivers sharp images.

Focus     back to Performance    back to top
Manual focus is easy.
Focus is as smooth as silk, perfectly damped with no play.
The D3D700F4F6 and most professional AF cameras have three very precise electronic manual focus indicators.
Lesser digital cameras, like the D300 and down, usually have just one "OK" focus dot, which is not as precise as two arrows and a dot.

Distortion    back to performance     back to top
The Nikon 55mm f/3.5 has no visible distortion.
For scientific use, plug 0.20 into Photoshop CS2's lens distortion filter for shots made at infinity on film or FX.

Falloff (darkened corners)    back to performance     back to top
Falloff on FX is negligible.
It won't be an issue at all on DX (see crop factor).
I've exaggerated this by shooting a gray field and placing these on a gray background.

Sharpness    back to Performance    back to top
With those caveats, the 55mm f/3.5 Micro-NIKKOR is super-sharp. It makes newer zooms like the awful 24-120mm VR look as bad as they are.

At infinity on a D3:
At f/3.5 and f/4
The center is super-sharp. The corners are sharp, but with a little less contrast.

At f/5.6
Everything is super-sharp side to side.

At f/8
Everything is super-sharp, and even the farthest corners are perfect. f/8 is optimum.

At f/11
As good as f/8.

At f/16

At f/22
Diffraction limits performance.

At f/32

Usage  back to top
It's easy, just focus and shoot.
If you need to get closer than 9-1/2," use the PK-13 extension tube to get to 1:1 (life-size at the sensor or film).

Exposure Compensation for external light meters
Nikon 55/3.5
Focus scale at close focus, Nikon 55/3.5. enlarge.
When focused closer, the lens extends away from the film or sensor. Since the mechanical diaphragm doesn't open to compensate, less light makes it to the film or sensor.
All modern Nikon cameras have their light meters built-in, so they automatically correct and use a slightly longer exposure time.
If you're using a hand-held meter (or non-TTL flash), here is the additional exposure needed as you get closer.
If you do this often, it's much handier to write these factors on a piece of removable white label attached to the focus ring. This way you can read the factor right off the lens as you focus. I simply put dots to mark how many third-stops are needed at the right spots on the front of the focus ring.
R = Reproduction Ratio.
Exposure Factor = (1 + R)2
Stops Compensation: Log2 (Exposure Factor)

Recommendations   back to top
The f/2.8 manual-focus 55mm lens is a tiny bit sharper in the corners wide-open at infinity, as are the other f/2.8 55mm and 60mm lenses. Then again, for $65 used, you can't do much better at any price for a lens better than this f/3.5. Stopped down to f/5.6 or f/8, nothing is sharper. Even at f/3.5, the resolving power in the center far exceeds the D3X; just peer through a Lens Scope Converter and you'll see far more detail than you will in a D3X file.
I prefer a 105mm lens or longer for my macro work to allow enough distance for my lighting, or to put little bugs at ease. Friends use this focal length for photographing fish in aquarium tanks. The short focal length allows one to get close to the glass and still be able to see a complete fish, unlike a 105mm.
If you want a macro for duplicating documents then this is a good choice. If you want to photograph little animals, then go instead for a 105mm macro.
The 55mm Micro works great in place of a faster normal lens. When I was younger and stupider I thought that it would not be very good when used at ordinary distances. Whoops, it's spectacular at all distances. Unless you need the extra stop or two offered by the other 50mm normal lenses, you can forget about needing a separate normal 50mm lens if you have this.
