🧠Uncovering the secret to creative thinking
Congrats to Dr @C__OCallaghan A. Prof @jmacshine and Dr @eli_j_muller awarded $1,076,895 by @arc_gov_au to unlock the brain’s mechanisms of compositional cognition.

A very exciting episode out now — our very own @bethfisher_1 tells us all about optimism! Beth shares work on psilocybin administration in rats🍄 and how optimism shapes our engagement with the world.
We hope you enjoy listening as much as much as we enjoyed recording this one!

@LabLuthi uncovers a dual role of #locus @coeruleus in #sleep -> 1) its strict gatekeeper role for the sleep cycle 2) the partial brain-body arousals it generates. Powerful minds behind all this: @alejandrosoriof @GFoustoukos @CardisRomain

My paper is out!! 🎉
"Opponent control of reinforcement by striatal dopamine and serotonin", @Nature
Here, we show that dopamine and serotonin signals form a gas-brake system for reward in the mammalian brain 🧠

The Laurent group is back again working with the pogona. They found that light pulses can reset or entrain the alternation between REM and slow wave sleep. Through careful tests, they conclude that this ultradian rhythm works like a CPG. nature.com/articles/s41586-0…

Adult human brains have between 86-100 billion neurons and every single one is unique - like snowflakes! ❄️
In this 3D rendering by our #ElectronMicroscopy team, we see 3 different shapes incl. (from left to right) a basket cell, tufted excitatory cell, and a Martinotti cell.

Nice results. You can't understand cortex w/o the thalamus
Primate thalamic nuclei select abstract rules and shape prefrontal dynamics

They also find a spectrolaminar cortical motif like this study:

Our latest in @TrendsCognSci on embracing, rather than mitigating, variability in the search for biological mechanisms of psychiatric disorders
Available here: authors.elsevier.com/a/1k32t…
Thanks to the dream team (@AFornito, @JegTiego, @LindenParkes, @AvramHolmes, @amarquand)!
Concerned about standard case-control studies in psychiatry?

Born #OnThisDay in 1934 was astronomer, astrobiologist and science communicator Carl Sagan. As well as being one of the world's greatest science communicators, he worked on the Viking and Mariner missions. Listen to his famous 'Pale Blue Dot' monologue: bit.ly/2ANRX30

Our latest PP led by @IvaIlioska, in collab. w/ @NSB_Lab @DondersInst. We use normative modelling to characterise the inter-individual variability of FC alterations in people with autism from individual edges to macroscale networks:

Short lecture by Kurt Vonnegut on the 'simple shapes of stories.'
Or storytelling + data visualization + data visualization about storytelling = mind blown.
