@engunimelb @nhmrc @davidgrayden @Bionics_Sejohn @UniMelbMDHS Congratulations to David, Sam and the team.

[Sagar @VidyasagarLab]

Congratulations @davidgrayden @Bionics_Sejohn and team for securing the grant!

[Sagar @VidyasagarLab]

Congratulations to Katya Levichkina
@sleep_volunteer and team for discovering how #somatosensory and #visceral signals are neatly separated in time in their transmission through #spinal_cord - one when awake and the other during #sleep!

[Frontiers - Network Physiology @FrontNetPhysiol]

🗨️ Check out this research from Dr. Levichkina:

"Solving a century old puzzle of somatovisceral convergence in the spinal cord: somatosensory information is transmitted mainly during wakefulness and visceral signals in sleep" 🛌

Paul Martin’s @Sydney_Uni lucid commentary on paper in @ScienceMagazine by Liu et al on how population of #melanopsin containing primate #retinal cells encode big range of irradiance. Regulate sleep, attention and brain's energy use. https://t.co/TpP4RNoyGY

Excited to share our review paper on neural mechanisms of error monitoring & origin of associated EEG biomarker. We see remarkable parallels between monkey & human results. Enjoyed working w/ @brooksfu_neuro @UeliRutishauser @LabSchall @stevenerrington.

@BRT_LungGuy @UniMelbMDHS Congratulations, Bruce. Great news.

Severe #COVID could cause markers of old age in the brain. This seems to happens even in younger people having severe disease. May explain cognitive deficts of long covid. So best to avoid the infection at any age. https://t.co/JZP0LhS9AC

This has the potential to be a real game changer in controlling #Covid by preventing transmission of #SARSCoV2. https://t.co/9enMXzmBtA

"If you think scrapping COVID isolation periods will get us back to work and past the pandemic, think again". Well said, @Globalbiosec @CrabbBrendan @enenbee. Very wise, expert advice. Not to heed will be to our peril. https://t.co/RMaXXP7gPx

Highly feasible suggestions from @TonyBlakely_PI for making NHMRC funding far less subject to statistical noise and assessor bias. Sorely needed to improve system, with funding in real terms falling for a decade. https://t.co/RTHiG9TcJa via @ConversationEDU

Parietal cortex is critical for both accumulating sensory evidence and also making decisions based upon that evidence. Article in @NatureComms by @yang_tianming & colleagues https://t.co/4hUvwxBobl

Why are we blind to data? Deaths, far more hospitalisations & long Covid are all overlooked. If govts don’t mandate, let’s lead ourselves with indoor masks and physical distancing. For how HCWs suffer & also light at the end of the tunnel: https://t.co/iaXthLKCzZ

[IPCC @IPCC_CH]

The latest #IPCC #ClimateReport shows that balanced, sustainable healthy diets such as those that include plant-based foods can help reduce emissions that contribute to #globalwarming. 🥦 🫘

New perspective piece on cognitive control with @CamdenMacDowell and @tafazolisina. We propose the brain uses a low-dimensional set of 'control states' to balance between precision of control with flexibility of learning. https://t.co/ZMvKvpYaKg

Congratulations to LaclanLo DaZhou @DrLaurenAyton @BangvBui @davidgrayden Morokoff @cephalad & @Bionics_Sejohn for providing proof-of-concept for developing a device to quickly & non-invasively gauge severity of head #trauma @UniMelbDOVS @UniMelbMDHS

[Luiz Pessoa @PessoaBrain]

Another 𝗻𝗲𝘂𝗿𝗼𝗮𝗻𝗮𝘁𝗼𝗺𝘆 𝗯𝗼𝗼𝗸 that I highly recommend is this really excellent book by Gerald Schneider: Brain Structure and Its Origins. Comprehensive treatment of brain anatomy from a strong evolutionary standpoint. Some of you will enjoy!

[Sagar @VidyasagarLab]

Covid behaviour seems unique: tunnelling into brain from nose, reaching cells w/out #ACE2 receptors! Do any other viruses do this? Experts warn of new variants more infectious & vaccine resistant. Masks & density limits work. So mandates needed till better vaccines & treatment.

[New Scientist @newscientist]

Covid-19 can cause brain fog and confusion in some cases, with new research suggesting the coronavirus enters the brain by building tiny tubes it shuttles through from nose cells https://t.co/75Pc4euwP3

Very useful and insightful review by @clairebradleyh @AbbeyNydam @PaulEDux @jbmattingley published in @NatRevNeurosci for understanding when to apply deep brain stimulation and why.

[Nature Mental Health @NatMentHealth]

The effects of neurostimulation depend on brain state. This has major implications for therapy and research. Find out why in this wonderful review by @clairebradleyh @AbbeyNydam @PaulEDux @jbmattingley published in @NatRevNeurosci
