Music and Wake Up Yoga With Mandy Ingber and Jennifer Aniston

It�s 4 a.m. in Miami and I�m in Jennifer Aniston�s hotel room. Atlantic Ocean views are hiding behind an early morning blanket of dark blue black. I�m there to run her through wake-up yoga before she gets to work on the set of her latest film, Marley and Me.

Now, Taoist meditators claim that the most potent energy of the day is the early morning energy at 4 a.m. I learned this like folklore from my father, the man who introduced me to yoga at age 6. That said, 4am in Miami is still 1 a.m. in L.A�.and I am exhausted. But I have a secret weapon that will get me, and Jen, through this workout. Music.

Where words fail me, music fills in. In my nearly 12 years as an exercise instructor, I try to tell a story with my classes. The music helps me take the class on a journey. Set the tone with the first song�.something hopeful and light. I allow myself to feel open�the music begins to move me. I find my breath syncopating with the rhythm of the music. We build into sun salutations to greet the day. Our bodies take over, and before you know it, we are harnessing that early morning energy.

Drums represent my heart, wind instruments my breath, guitar sounds like the feeling of that burn in my glutes when I sink into chair pose. Rhythm helps our breathing patterns and our movements fuse. I feel alive, and like I have accomplished a great feat, just by keeping up my regular physical practice, which I share with this other woman I see before me.

My yoga practice started when I was just a kid. In the �70�s, my dad practiced yoga in our stark living room to Elton John. In the late �80�s I found myself practicing yoga with Woody Harrelson and Laura Louie, chilling out in partner poses to Bob Marley. In the late �90�s I turned to the irreverence and sexuality of hip hop music: took my t-shirt off and got my Tupac on. But regardless of the genre of music that was the background, it helped me to connect my mind and body through my emotions. MUSIC MAKES ME FEEL.

And that�s what it did for us that day.

Twist, arch, fold, hold, lunge, extend, balance, rise. inhale, exhale, breathe, relax, salute, jump, sit, rest. As we breathed with the music, we allowed the music to guide and inform our movements. The sequence started to flow on its own and the yoga happened with little effort. By the end we saluted one another in namaste. She runs off to shower and readies herself for work. And I crawl back into my bed and close the black out shades. With the most potent energy of the day coursing through my body, I put myself right back to sleep. � Mandy Ingber

There is also a list of the music they listened to at the website which inculdes a song by john mayer.

Scientists discover single brain cell dedicated to Jennifer Aniston inside woman's head
By Fiona Macrae

It is a discovery that could explain the enduring appeal of Friends. Scientists have found brain cells devoted to Jennifer Aniston.

Fans of the actress, who played socialite Rachel Green in the Channel 4 sit-com, are likely to have at least one brain cell that springs into action each time they see a picture of her, research suggests.

Other brain cells are similarly encoded to store memories of individual celebrities, from actress Halle Berry to former US presidents Bill Clinton and Ronald Reagan.

Even Star Wars character Luke Skywalker has a cell of his own.

The Leicester University research, contradicts the popular theory that a large network of cells are involved in processing images of people.

Instead, it appears, our brains streamline the process by devoting individual cells to store memories of specific people or places.

Neuroscientist Rodrigo Quian Quiroga (CORR) made the finding after showing people being treated for epilepsy hundreds of pictures of famous people and of landmarks.

Tiny electrodes implanted as part of their treatment picked up the electrical activity or 'firing' of around 100 brain cells in each person.

Tests showed that one woman had a cell that specifically recognised pictures of Jennifer Aniston.

Another woman had a brain cell for pictures of Halle Berry, responding to drawings of her face and an image of just the words in her name.

Even a picture in which the Catwoman actress's face was almost covered by her costume made the cell fire.

Other celebrities exciting individual brain cells included Pamela Anderson, Oprah Winfrey and Tom Cruise. Famous landmarks also had their own cells.

The study also showed that the same person can have a number of cells devoted to different celebrities or landmarks.

Professor Quian Quiroga said: 'The patient with the Jennifer Aniston neuron had 19 other cells firing to different things.

'There was one firing to Pamela Anderson, another one was firing to the Tower of Pisa, another to Sydney Opera House and so on.'

Although the researchers only found one Jennifer Aniston or Halle Berry cell per person, they only sampled a fraction of the available brain cells.

This means each person's brain is likely to have a number cells devoted to their favourite celebrities.

It is likely we also have cells coded to recognise family members.

In further experiments, the researchers have shown it is possible to tell whether a person is looking at a picture of Jennifer Aniston or of Halle Berry simply by monitoring their brain cells.

Professor Quian Quiroga, who will give a lecture on his findings next week, said they could feed into research into the development of prosthetic limbs driven by the brain.

The work could also aid research into Alzheimer's disease, epilepsy, schizophrenia and other conditions which involve the area of the brain studied.
