Pretend Chat 2.14

[Yvonne G]

My son-in-law came over bright and early to get my new mower going for me. You all know those battery operated little toy cars for young kids to drive? My great grandkids have a couple of them - a tractor, a motorcycle. Well, my new riding mower looks like one of those toy cars, only bigger size for an adult. The battery needed charging, so he didn't get it running today. But while he was here I had him cut the hole through the side of the garage and into the Aldabra shed for the extension cord, and give me a quick tutorial on how to use the new air compressor (another toy-sized object) he gave me for Christmas. The cactus cutting guy is coming tomorrow instead of today.

Of course, you know we MUST see pictures!!!!

It's not all that picture worthy yet . Just two hides and a water bowl . Right now they are sleeping away winter .

lets just see pics

 

[mike taylor]

I'll get some tomorrow .

 

[mike taylor]

Monica this one's for you .

 

[Cowboy_Ken]

working with the bacon equals madness haha.
How are you?

I'm well, thanks hon. I've been eating out a lot lately mainly due to laziness. I hate washing dishes and love to make dirty ones, sooo, easiest solution for me is to be served. And I'm a firm believer in tips,(To Insure Prompt Service), I tip Chefs when deserved.

 

[Elohi]

Monica this one's for you .

LMAO!!!

 

[Jacqui]

Seriously! Where are all the chatters?!?!
What's everyone doing on a Friday night?!?!
Watching a moving, eating out, drinking or curled up with a good book!?!

Sleeping.

 

[Jacqui]

Okay Mike, what are the new ones?

 

[Jacqui]

Good evening all!

 

[Jacqui]

So sorry! Throwing up is the worst!!!

I agree.

 

[gamera154]

Who knows who gamera is

 

[MPRC]

STILL naseous. STILL not sick though. Its driving me nuts.

Pregnant?

 

[Jacqui]

Who knows who gamera is

You or the large monster?

 

[Jacqui]

Good morning!

 

[Jacqui]

Was a beatiful 70 degree day here today. Was sweet having the window open, a cool breeze blowing across me and windchimes making music. Tomorrow (today) will be 10 degrees cooler and atleast another 10 mph on the wind. Snow by the middle of the week.

 

[Jacqui]

Once more, Jeff has spent several days in Nebraska, but I haven't gotten to see him.

 

[gamera154]

You or the large monster?

the monster

 

[Cowboy_Ken]

Does it matter if I post this entertaining and interesting (to me) stuff here? Say the word and it will never happen again…


How brain oscillations might respond to teleportation
25 Feb 2016, 10:57 AM

Subjects navigated an on-screen environment including teleportation while their brain waves are recorded from intracranial electrodes. Subjects were asked to find the grocery store located in a wide streetscape. (Lindsay Vass, UC Davis)
Technology may not have caught up to the teleportation devices of science fiction, but now we have some idea of how the brain handles "beaming up" from one location to another, thanks to research by neuroscientists at the University of California, Davis, involving some specially wired volunteers.

The work is published online Feb. 25, 2016 in the journal Neuron.

Arne Ekstrom, associate professor at the UC Davis Center for Neuroscience, wants to know how we memorize places and routes, and learn to find our way around. It's long been known that as a rat navigates a maze, its brain gives off a rhythmic oscillation, Ekstrom said. This also happens when humans travel around a virtual landscape on a computer screen. Most models of brain function assume that the oscillations, emanating from the hippocampus deep inside the brain, are at least partly driven by external inputs.

"There is this rhythmic firing in the brain during navigation and while remembering things, but we don't know if it is triggered by sensory input or by the learning process," Ekstrom said.

Ekstrom, postdoc Lindsay Vass and graduate student Milagros Copara were able to solve this problem by working with a group of patients being treated at UC Davis' Department of Neurological Surgery. These patients have a severe form of epilepsy, and surgeon and study coauthor Kia Shahlaie implanted electrodes on their brains, inside the skull, to find out where seizure activity begins and identify treatment options.

In between seizures, the electrodes recorded normal brain activity, and three patients volunteered to take part in the experiment. They were asked to navigate through a streetscape on a computer screen. At some points, they entered a teleporter and jumped to a different, known location in the map. During teleportation, the screen went black for a random period of time.

Teleportation did not interrupt the oscillations at all, but the rhythm did change with the distance travelled during teleportation, Ekstrom said.

The results show that these oscillations are driven entirely by memory and learning processes in the brain, and do not depend on external senses. They also show that the oscillation carries information about speed and distance travelled, even when that travel is virtual teleportation.

Additional coauthors on the study are Masud Seyal, Sarah Tomaszewski Farias and Peter Shen at the departments of neurology, neurological surgery and radiology, UC Davis Health System. The work was supported by the NIH.4
