Excited to share with you all the latest paper from @LabMirzaa : an intriguing (I might be biased) story on inverse brains growth phenotypes due to mutations in proximal vs distal regions of CCND2. #research #neuroscience #raredisorders…
We found that frameshift and nonsense variants in the proximal domain of CCND2 lead to microcephaly, short stature and mild intellectual impairment in three unrelated families.
Previous findings from our lab and other had associated missense variants in the distal region of CCND2 to MPPH, a complex phenotype with megalencephaly.

#NoEstimates, un mouvement hétérogène et controversé lancé en 2012 sur Twitter 🔮

Le sujet vu par @ddreptate dans un meetup organisé par @ByondSM 🧶 Image
—On est mauvais à estimer (+ c’est gros — on est précis)
—Processus fastidieux
—Détourne de la création de valeur (focus coût vs. valeur)
—Celle-ci vient de l’implication des personnes et de la capacité à apprendre rapidement dans un monde VUCA (rien de mécanique ou identique) Image
BIAIS COGNITIFS, une des raisons principales pour mal estimer

—Biais d’ancrage: on va tjrs rester figés sur une 1ere info, on sera influencés par ça
—Biais de confirmation: on donne + d’importance aux infos qui vont venir confirmer nos croyances

Neuroscience-inspired perception-action in robotics:
applying active inference for state estimation,
control and self-perception

🔎📚 Paper:
👨‍🎓 👩🏾‍🎓 Credit: Pablo Lanillos, Marcel van Gerven
Unlike robots, humans learn, adapt and perceive their bodies by interacting with the world.
Discovering how the brain represents the body and generates actions is of major importance for robotics and artificial intelligence.

Uyanık olduğumuz saatlerde beyin, neredeyse sabit bir duyusal sinyal akışı alır. Uzun yıllardır neden bazı sinyallerin bilinçli farkındalık oluşturup bazılarının oluşturmadığı tartışılıyor. Yeni bir çalışmada, araştırmacılar kortekste bilinçli farkındalığın kapısı gibi görünen
kilit bir alan belirlediler. Beyinde bilgi işlemenin iki boyutu vardır: çevrenin farkında olmadan duyusal işleme ve bir uyaran belirli bir önem düzeyine ulaştığında ve bilinçli farkındalığa girdiğinde ortaya çıkan diğer boyut. Araştırma ekibi bu değişimin beynin
anterior insular korteks adı verilen bölümünde gerçekleştiğini doğrulamaya çalıştı ve düşük seviyeli duyusal bilgi ile daha yüksek seviye farkındalık arasında bir tür geçit görevi gördüğünü buldular.

New preprint 📚🧠🧮🧒:
Oscillatory EEG Patterns of Arithmetic Problem Solving in Fourth Graders
We already have a pretty good idea how arithmetic problem solving is reflected in oscillatory EEG activity in adults:
Simple problems are usually solved by fact retrieval. In that case, we observe theta ERS (power increase). Hard problems need to be calculated, which is reflected in alpha ERD (power decrease).

Bonus: analisis ttg BRIN dan Babi Ngepet di bagian akhir slides (spt saya janjikan minggu lalu).😅

Soft Launching website baru UI.

Just finished a very intense 3 day @CFREF_APOGEE review of @Brains_CAN. So many positive and interesting discussions, and really good food for thought going forward. The present and future of #neuroscience @WesternU looks very bright to me.
The best part for me was seeing our @BrainsCAN @WesternU community engaging so enthusiastically in the process and really doing the business to show off the fantastic work going on here.
We have been working under extremely challenging conditions for over a year. We're all exhausted. Doing a review over webex is hard. But the brilliance and enthusiasm of our community shone through very clearly.

Here is why you can't STOP OVERTHINKING: A THREAD

Brain waves: Our brain produces 4 different types of waves depending on the activity-
Beta waves- When we are actively thinking
Alpha waves- When we are in a free flow of thought
Theta waves- When you are dreaming at night or daydreaming
Delta waves- When you are in a dreamless state
During Daytime: Our days are sometimes completely filled with activities and distractions such that we are always in a Beta wavelength.
This hardly gives our brain time to relax or go into any other wave state.

Check out my illustration on the course of the oculomotor nerve with its associated sites of injury!

Patients with an oculomotor (CN III) nerve palsy can present with binocular horizontal, vertical, or oblique diplopia and ptosis. (1/3)
In addition to extraocular muscle weakness, one may find a dilated pupils (mydriasis) due to unopposed sympathetic innervation to the pupil. Having an understanding of the course of the oculomotor nerve, and where injury can occur, leads to the production of a (2/3)
differential diagnosis, ordering appropriate diagnostic studies to confirm the cause of oculomotor nerve injury, and implementing appropriate management to best serve the patient. I hope you all enjoy it! (3/3).

Was #TheDarkKnight's Two-Face the product of brain injury? Harvey Dent was hospitalized after surviving the explosion and disfiguring burns that transformed him into the psychopathic villain, Two-Face. The background offers insight into the villain's psychological origins. (1/6)
A monitor shows a computed tomography (CT) scan of Dent's head, which reveals contusions (blood) in both frontal lobes of the brain. Such contusions are common after traumatic brain injury, resulting from the brain striking the front of the skull during sudden deceleration. (2/6)
The frontal lobes support higher-order cognition, such as planning, emotional regulation, and impulse control. The ventromedial prefrontal cortex (vmPFC), the frontal region most vulnerable to contusions, is important for moral judgement and emotional decision-making. (3/6)

I'm very much excited to share that our with Prof. @baths_veeky on Acoustic and Language-based deep learning approaches to Alzheimer's dementia detection from spontaneous speech has now been published at Frontiers in #Aging #Neuroscience @FrontNeurosci!…
Similar to how RNNs are trained on word embeddings and POS-tags for language based tasks, we propose recurrent stream which processes paralinguistic acoustic features and looks for temporal patterns relevant to early detection of dementia.
We show that enriching a recurrent feature processing stream with dementia specific features such as idea-density, disfluency, imageability and other psycholinguistic and interventional features helps improve performance in both natural and spoken language processing applications

"As QAnon influencers and their followers are pushed off mainstream platforms.... There, they may be exposed to more extremist content, like that of white supremacist and neo-Nazi groups."

So what is the right approach? No right answers.…
..soooo.. usually seek facts & ideas ...rather than go down rabbit holes of others’ 🤯

..but wow, some remaining QAnon-posting accounts are within 1-2 degrees of separation..

To FB’s credit, misinformation/disinformation posts get covered with a grey filter & this warning:
Since I am a Muslim woman on the highly armed alt right’s radar myself now

am curious to understand what kind of 👹 they perceive me to be - tho prefer to only a quick peek, not a deep dive

(Obviously @IlhanMN was not actually at any such training camp)…

Mice display empathy using the same brain structures as humans: Check out our paper in @ScienceMagazine about how distinct neuronal circuits are involved in empathy for companion mice who are experiencing pain or pain relief vs fear… Explainer THREAD 1/10
Rapid Social Transfer of Pain: Following only a 1h social interaction with a mouse experiencing pain, “bystander” mice acquire an aversive pain state. We believe this model demonstrates key components of empathy. #Neuroscience #SciTwitter #research #didyouknow 2/10
Rapid Social Transfer of Analgesia: We also found that after a 1h social interaction w/a mouse experiencing pain+morphine analgesia, “bystander” mice acquire pain relief in the absence of drug administration! Pain relief can be socially transmitted to a social partner! 3/10
