#Mouse filmed tidying up man's shed every night. Despite being an avid #wildlifephotographer retired postman Rodney Holbrook never expected to capture a Ratatouille-style scene unfolding in his own shed. After regularly discovering that things from the night before had been mysteriously tidied, he set up a night vision camera on his workbench. It captured a mouse picking up clothes pegs, corks, nuts and bolts. He has since nicknamed the well-kept rodent Welsh Tidy Mouse. https://www.bbc.co.uk/news/uk-wales-67902966
In case you wanted some of the keyboard, mice and other devices that Microsoft discontinued, Incase will be bringing them back as "Incase Designed by Microsoft" later this year.
I wonder if they will include the Copliot key.
The Verge: Microsoft's keyboards and mice will live on under a unique new partnership
Stavo pensando: da ora che ho la tastiera più piccolina per il #PC, e mi sa che mi trovo parecchio meglio ad usare lo #smartphone come #touchpad (per certi versi più comodo del #mouse normale per me) rispetto a quando avevo quella grossa, potrei quasi quasi comprarlo un touchpad #USB… 😁️
E però oh, non si trovano a un prezzo decente, né su Amazon né su AliExpress, eccetto per uno micragnoso brutto minuscolo (che comunque per il #prezzo è un insulto eh)… #mannaggia!!! E persino da alcuni cinesi locali non ho trovato; forse dovrei cercare meglio in tutti, ma a questo punto neanche ho la certezza di trovare qualcosa, figuriamoci di bono. 😩️
Altrimenti, questa è forse la volta buona che trovo un utilizzo pratico per il mio vecchio #Huawei distrutto, che sta nel cassetto a marcire (il vetro c’ha lo #spacc, ma il #digitizer funziona, e al tatto non c’è problema perché c’è una pellicola intatta sopra)… perché certamente col telefono primario, che mi serve per altro ed è pure bello cicciotto non posso andare avanti così. Preferirei comunque un vero touchpad però perché #KDEConnect#lagga, a meno di trovare #app alternative (o forse mi basta collegare il #telefono al PC con il #tethering USB?) 🐁️
YouTube's systems are confused. Steamboat Willie entered public domain today (Mickey Mouse's first appearance). I uploaded it to my YouTube, and YouTube systems are still drunk from last night. Fun with copyright disputes!
Maria Tosches & Heather Lee summarize the newly reported, and massive, atlases of mouse brain transcriptomics that include as well partial projectomes.
This was my very first screenprint which I offered for sale. (I did do a gig poster before this but it was pretty much a printing disaster).
I made this 7 almost exactly years ago.
This is called Teasel and Hare. I used a technique I called "digital linocut" but it was not great. It is not my best work but shows a point in time where I was starting out. It was an edition of 22.
Either the batteries I'm using for my #WirelssMouse are the wrong type of batteries, or the on off switch is going a bit glitchy, or metal clips in the little bed place where the battery lies have gone a bit loose ...
Because occasionally when I turn my #mouse on, it decides not to work.
Why I was on the point of buying a trackball mouse but did not
Firstly, I would not have had to pay for the mouse, so money was not the deciding factor (my medical insurance gives me rewards for exercising along with a 20% discount which would have covered the full cost).
I liked the idea of the trackball mouse, mainl ...continues
Just a reminder that today — December 9, 2023 — is the 55th anniversary of “The Mother of All Demos,” the 1968 demonstration of technology that we all use today, but must have seemed like pure science fiction back then.
Periodic reminder of what fMRI's BOLD signal is measuring, and its temporal dynamics:
"blood oxygenation level–dependent (BOLD) contrast. [...] increased signal in a voxel measured with an EPI [echo planar imaging] sequence indicates recent neuronal activity because of the relative increase in local blood oxygenation that accompanies such activity. The temporal profile of this BOLD response, known as the hemodynamic response function, looks like a bell curve with a long tail, peaking around 4 to 5 seconds after local neural activity and returning to baseline after 12 to 15 seconds."
From "Principles of Neural Science", Kandel et al. 6th edition, page 115.
No matter how fast the EPI imaging is (~100 ms), the BOLD dynamics makes GCaMP look lighting fast. Temporally deconvolving BOLD is possible, to a point, but remember its spatial resolution is measured in millimetres, whereas neuronal somas measure ~0.025 millimetres.
... where they report "an additional and equally direct pathway for cortical motor control driven by the primary somatosensory cortex" in mice. This surprising result, breaking with Penfield's century-old division of labour between the motor cortex and the somatosensory cortex, is supported by voltage-sensitive dye (VSD) imaging of the whole mouse brain, showing widespread activity propagation with latencies of tens of milliseconds across most of the whole brain.
Suppose we were to attempt a similar measurement in humans with fMRI. What would we see with the very low pass filter in the temporal and spatial dimensions that we get from fMRI?
Perhaps this is indeed the wrong question, and in humans we ought to be asking different questions. But what questions? Matyas et al. highlights:
(1) how fast and wide signals spread across the whole mammalian brain;
(2) the inaccuracy of old neuroanatomical divisions of the brain;
(3) the fact that a much larger fraction of the brain is involved in any one behaviour than previously thought, larger than would have been ideal to make sense of the brain as a modular system when its activity is monitored with the low pass filter that is fMRI.
My question is: what kind of studies are sensible given fMRI's strengths and limitations? I have one example in the next post.
