Doggie MRI

dogs, pets, research

By placing dogs in an MRI scanner, researchers from Hungary found that the canine brain reacts to voices in the same way that the human brain does. Emotionally charged sounds, such as crying or laughter, also prompted similar responses, perhaps explaining why dogs are attuned to human emotions.

The work is published in the journal Current Biology. The full article is @ BBC.

Eleven pet dogs took part in the study; training them took some time. “We used positive reinforcement strategies – lots of praise,” said Dr Andics. “There were 12 sessions of preparatory training, then seven sessions in the scanner room, then these dogs were able to lie motionless for as long as eight minutes. Once they were trained, they were so happy, I wouldn’t have believed it if I didn’t see it.”

Science proves that you love your dog like a baby

Interesting article about pets and how humans react/respond to them. From the abstract:

Neural substrates underlying the human-pet relationship are largely unknown. We examined fMRI brain activation patterns as mothers viewed images of their own child and dog and an unfamiliar child and dog. There was a common network of brain regions involved in emotion, reward, affiliation, visual processing and social cognition when mothers viewed images of both their child and dog. Viewing images of their child resulted in brain

activity in the midbrain (ventral tegmental area/substantia nigra involved in reward/affiliation), while a more posterior cortical brain activation pattern involving fusiform gyrus (visual processing of faces and social cognition) characterized a mother’s response to her dog. Mothers also rated images of their child and dog as eliciting similar levels of excitement (arousal) and pleasantness (valence), although the difference in the own vs. unfamiliar child comparison was larger than the own vs. unfamiliar dog comparison for arousal. Valence ratings of their dog were also positively correlated with ratings of the attachment to their dog. Although there are similarities in the perceived emotional experience and brain function associated with the mother-child and mother-dog bond, there are also key differences that may reflect variance in the evolutionary course and function of these relationships.

A study of dog DNA has shown that our “best friend” in the animal world may also be our oldest one.

The analysis reveals that dog domestication can be traced back 11,000 years, to the end of the last Ice Age. Read the entire article @BBC

When the coronavirus pandemic emptied offices earlier this year, forcing millions of people to begin working remotely at home, some began to feel like they needed a new friend to replace the water cooler banter. Now at home all day and needing a happy distraction from the pressures of the precarious state of the world, they decided it was finally time to act on a long-held goal of adopting a pet.

The US Army has shown off augmented reality goggles for combat dogs, designed to let them receive orders at a distance.

The technology, made by a firm called Command Sight, is managed by the US Army Research Laboratory.

Military dogs can scout ahead for explosives and other hazards, but need instructions.

The goggles are designed to let their handlers direct them, safely out of harm’s way. READ ARTICLE AT THE BBC HERE
