My dog Barley had a stroke a few months back and since then has been displaying signs of unilateral neglect. I've written about it more here: http://statisticallysignificantscience.wordpress.com/

This video shows only the last few seconds of her eating but seems to suggest she is 'unaware' of the left hand side of the bowl. This is strange as you'd imagine her olfactory sense would tell her there is still more food. If only she walked back to the bowl from the other side she'd have realised!

Please feel free to use this or any of the photos on the blog for lecture purposes.
Will probably upload a longer video soon.

  • Thanks for all the comments on this video, just to let people know watching in future Barley passed away (finally) a few months ago. Turns out she had advanced cancer, which was probably affecting her brain and causing/not helped by the strokes. She continued to just eat food from one side the whole time until she passed. Not convinced myself that it was a true case of unilateral neglect but it was definitely something like it. I guess we'll never know for sure. Hope it helps some lecturers. O

  • A neighbour of mine has a dog with the same problem.

  • @hanswatson How did you manage to complete this comment as a full sentence? Do you not see it but in a dactylographical way just know what you've written? I'm curious!

  • The problem isn't smell or sight or anything of the sort. Your mind actually neglects anything on that side. Your eyes still see the food but your brain does not process the image. I could only assume the same thing happens for smell. Her nose smells the food but her brain does not process that it is there. I'm very sorry for your loss!

  • @pussylumpessru I don't think smell has spacial discrimination (e.i. if you kept your head fixed and someone farted around you, you can't tell who the perpetrator is).

  • what about her sense of smell. Does her nose pick up the food to the right?

  • Cuuute dog !!

  • Would have been interesting to turn the dish around, or have the dog walk to the other side of the dish. If it is truly spatial neglect, Barley would have started to eat the "new" right side

  • very interesting

  • i dont understand why the other senses don't override the neglect (well in the case of food anyway)
