Tu perro sí entiende lo que le dices y cómo se lo dices

Tu perro reacciona a cada vez que pronuncias su nombre, pero a veces pareciera que entiende perfecto cuando le das una orden en particular o cuando le estás diciendo palabras de amor. ¿Será que su cerebro entiende los sonidos de tu voz?

Cuando alguna persona te habla, algunos sonidos de su voz se combinan para formar palabras y otros más transmiten emociones. Tu hemisferio izquierdo es el encargado de procesar el primer tipo de sonidos, mientras que el hemisferio derecho se especializa en los segundos. Los perros tienen el mismo tipo de funcionamiento cerebral cuando se trata de sonidos perrunos, pero quedaba poco claro si era así con sonidos humanos.

Para responder a esta pregunta, un equipo de investigadores británicos les hicieron escuchar a un grupo de perros una orden grabada –ven- y luego observaron hacia dónde se dirigieron los animales. 

Los resultados mostraron que cuando los perros escucharon palabras individuales con un énfasis fuerte, voltearon a la derecha, lo que indicó que su hemisferio izquierdo estaba comprometido. Por otro lado, cuando escucharon grabaciones con entonaciones exageradas, voltearon a la izquierda en tanto que su hemisferio derecho estaba respondiendo.

El análisis muestra que los perros procesan los elementos del lenguaje de los humanos de una manera similar a como nosotros lo hacemos. Los investigadores mencionan que nuestros perros sí ponen particular atención a quién lo dice, cómo lo dice y, más importante, qué dice.

Yes, why not? :-)

Our brain has us locked in strict rules that can’t be bent. Or so we are thought to believe…

And prob one of the reasons why we find this funny. If you remove the animals, and replace them with humans the ad is “nothing”.

We are always interested by things regarded as impossible, but the rules of impossible are only fabrications made by our brain.

I still regard that “nothing” is impossible…

Hope you all have a great weekend!!!

Hurtling Hurdlers

Reactions are never quite ‘lightning quick’ because impulses flashing along nerve channels must hurdle the tiny gaps, or synapses, between neurons. Chemical messengers – neurotransmitters – are stored at synapses in tiny pods called vesicles, some of which are primed to release their cargo in an instant to speed an arriving impulse across the gap. Recent advances in 3D microscopy have enabled this hair-trigger mechanism to be studied in detail. Scientists used this picture of a section of mouse’s brain to locate the position of synapses, then looked inside them to observe vesicles fusing with neuron membranes and breaking open. Further experiments identified several proteins controlling this process. This research is important to the understanding of a range of illnesses associated with the malfunction of synapses, including Parkinson’s disease.

What Matters to Me


These last few weeks I’ve had to think through some tough decisions on where my life was heading. Although I haven’t settled on something just yet, I became a lot more comfortable with the possible outcomes—after thinking about the things that really mattered to me in life.

It wasn’t easy thinking about these things. Looking back at my life, things that I thought would be good opportunities for me could turn into the opposite. They actually hurt my sense of self and what I wanted to do in the world. Taking a new life direction just for things like the money or a shiny promise of ‘being better’ weren’t things I set out to do, but it’s hard to say ‘no’ to opportunities like that if that’s what your career direction is *supposed* to go in.

I’m trying to shift myself away from the template that I was following. It’s not just because I want to do something different—it’s because I don’t feel like the person I know I want to be. Part of this shift involves figuring out what I really want in life, and I’ve tried to be as specific as I can—without limiting myself to these things. I found that there weren’t too many things that I couldn’t live without, but they’re not small things by any means. They take a lot of time and care to make up the inspiration for things in my life.

Love & support
I wouldn’t have gotten this far in my life without the love and support of my family, friends, and my wife—who’s there to walk me through my issues almost every day. It’s so important to have as much of these people around me as possible, and keeping a healthy relationship with them. I’m constantly amazed with how talking to these amazing people about my problems can make the whole day better.

Although it helps to have digital stuff to communicate with them when they’re not close, I still prefer being with them in-person. Being able to travel to these people within a day makes such a difference, and you can do things like sharing a meal or coffee over conversation. I love experiencing wonderful things with equally wonderful people.

A place I can respect
I’m a huge believer in positive people inspiring other people, and especially when it’s on a city-wide scale. No city is without it’s problems. But I’ve become a big fan of Vancouver, where I’ve been living for the past 6 years. It’s grown into a city with some amazing community programs and initiatives—which I’ve grown to be a part of in the past few years. Things like the Gordon Neighbourhood House, the Vancouver Bienniale, Neighbourhood Small Grants, and VIVA Vancouver have completely transformed my idea of what this city is. They show that people really care about their communities and want to make them even better than they are now. Apart from it’s beautiful spot perched between mountains and the ocean, these things make the city a place I really respect. A place I’d like to keep growing in. It makes me excited to see what kinds of things will happen in the near future.

Making an impact in my community
Over the last few years, I’ve become much more aware of the place I’m living in and the responsibility that comes with that. Especially in a larger city, the things we do on a personal scale have effects on the shared buildings we live and work in. These could be things that prevent bad stuff from happening, like recycling or garbage collecting to keep litter off the streets. Or they could be celebrations of being together, like having a potluck or barbecue to meet your neighbours. But as long as I have a chance to get involved in things like these, I’m happy.

During a hike with some friends last week, I went a bit off the trail and into a thick patch of trees for a bit. As far as I could see, there were mossy trees everywhere. Although there was no clear path or organization to them, but they seemed to be aware of their space between each other. I didn’t see many trees growing right up against another, invading another’s space. Each tree seemed to work with the space it had, and grew to be these amazingly lush, tall things.

After sitting on the things that matter most to me, that’s the more of what I want to achieve. Working with what I have, where I’m at, and staying true to the things I care about. That way, I hope I can keep growing into something grand like those trees.



Brain scans reveal what dogs really think of us

 Thanks to recent developments in brain imaging technology, we’re starting to get a better picture of the happenings inside the canine cranium.

That’s right — scientists are actually studying the brains of dogs. And what the studies show is welcome news for all dog owners: Not only do dogs seem to love us back, they actually see us as their family. It turns out that dogs rely on humans more than they do their own kind for affection, protection and everything in between.

Did you know that gray matter, which makes up 40% of the brain, doesn’t turn gray until after death? A living brain has a more pinkish hue, and, according to scientists, feels similar to tofu.

More interesting brain facts can be found at Mic, where we’re partnering to share the latest advances in brain research and technology with a one-month series exploring the universe in our heads.
