Visual cortex is affected by sounds. Does this mean it is multisensory? Does it represent sounds?

Today in Nature #Neuroscience (doi.org/10.1038/s41593-022-012) Célian Bimbard and team find otherwise.

Sound-evoked activity in visual cortex was similar across neurons. Even neurons in hippocampus. It persisted after we cut fibers from auditory cortex!

This activity was predicted by… subtle body movements evoked by the sounds. It reflects brainwide state and behavior signals.

Our work on post-encoding memory reactivation is finally out in @JOCN_Journal@twitter.com: direct.mit.edu/jocn/article-ab

A huge thanks to all my co-authers: Xavi, @aya_benya@twitter.com, @BStaresina@twitter.com and @llfuentemilla@twitter.com, and also the reviewers who helped improve the paper to its final format!

Post-encoding Reactivation Is Related to Learning of Episodes in Humans

Abstract. Prior animal and human studies have shown that post-encoding reinstatement plays an important role in organizing the temporal sequence of unfolding episodes in memory. Here, we investigated whether post-encoding reinstatement serves to promote the encoding of “one-shot” episodic learning beyond the temporal structure in humans. In Experiment 1, participants encoded sequences of pictures depicting unique and meaningful episodic-like events. We used representational similarity analysis on scalp EEG recordings during encoding and found evidence of rapid picture-elicited EEG pattern reinstatement at episodic offset (around 500 msec post-episode). Memory reinstatement was not observed between successive elements within an episode, and the degree of memory reinstatement at episodic offset predicted later recall for that episode. In Experiment 2, participants encoded a shuffled version of the picture sequences from Experiment 1, rendering each episode meaningless to the participant but temporally structured as in Experiment 1, and we found no evidence of memory reinstatement at episodic offset. These results suggest that post-encoding memory reinstatement is akin to the rapid formation of unique and meaningful episodes that unfold over time.

@neurrito Thanks! Using Blender really opens up a whole new range of possibilities for scicom. When I started using it I had no experience with 3D animation. It took a few weekends to get into it, but def worth the effort, it's so much fun!

For reference, the average low temperature for Cambridge (UK) in January is ~2C and happens around 6-7 AM. We are 11 degrees Celsius above the average minimum temperature.

What will happen if we’ll RETHINK our street corners?

We'll realize that until now, we've made them too car-centric. Street corners are designed for fast driving, which means pedestrians have to risk their safety just to cross the street.

But if we’ll rethink our street corners we’ll get

■ More space for pedestrians
■ Shorter crossing distance and time
■ Greener spaces
■ Safer Streets
■ Beautiful street corners

A great example from PGAA Creative Design in Manila

When you’re three months into that side project you said would take a weekend.

@akundaje Thank you for sharing this, I find it very useful!

What's the carbon footprint of a Christmas tree? I don't know, but for those lucky enough to have a garden there is a carbon-negative alternative: a living Christmas tree!

A few years ago I planted a tiny Tannenbaum which has been eagerly growing ever since. For a few days every year It seems to enjoy the outfit.

@brendonowicz Thanks! Excellent question.. If that input from the amygdala (via direct or indirect connections) triggers an action potential burst, and DA is present then this could trigger this type of plasticity. We have shown it only for the hippocampus, but it may well also work like that in other brain areas..

@albertcardona Thanks, Albert, very happy you enjoyed the video. Blender really is an amazing tool providing a wide range of possibilities for all sorts of scicomm!

Welcome new Twitter migrators!

Somewhat new myself. Some insights you might appreciate:

➡️ It only appears “dead” here as long as you don’t follow a couple hundred people. Just follow, follow, follow… you can later be more selective!

➡️ There is no “algorithm” deciding what you see, so you need to boost toots to give them traction.

➡️ “Liking” is less of a thing here, so don’t be discouraged.

➡️ Ppl describe the content of attached images. I love this! It gives extra depth to your toot! See 👇👇👇
