We also examine how this modulation is affected by aging and pharmacological manipulation.

[Utku Kaya @afimxat]

We show that hippocampal theta frequency is dynamically shaped by recent sleep history: sleep lowers waking theta frequency, whereas sleep deprivation maintains it at a higher level until recovery sleep.

📑This morning @SfNtweets, check out the poster by the Rothschild lab, presented by Utku Kaya. They show spatially-selective sensory information coding during navigation. Board U28

Excited to share my recent work, part of my PhD thesis under @SharpWaveRipple, on the effects of sleep loss on hippocampal function. Check it out here: https://t.co/HdN4Q5Ekzz.
Many thanks to @SharpWaveRipple and @TedAbelneuro for the opportunity to work on this project.

Very proud of @KouroshMaboudi for his conscientious work on https://t.co/KbZ8DtCA2G, where he developed and applied a new method to track the spatial tuning of hippocampal neurons during offline periods and found that they can change during ripples after maze exposure. 1/3

@burakkayaburak Ya da baska bir deyisle, zihnin soyutlanmasi mumkun degil. Soyutlandiginda hizli olmasi mumkun ama hizlanan seyit zihin oldugunu iddia etmek fazla hirsli olacaktir.

[Utku Kaya @afimxat]

@burakkayaburak Guzel soru. Insan zihnini veya zekasini computational bir modelle ele almaktan kaynaklanan bir yanilgi var. Genellikle survival mekanizmalarinin tumu evrimsel modellemenin ustaligi ile sekilleniyor, canli biyolojisi gerektiriyor. Aslinda temel sorun hiz degil, nitelik.

[Utku Kaya @afimxat]

@burakkayaburak Teoride biyolojiden soyutlanmis bir matematiksel modelin calismasi mumkun degil. Biyolojiyi dahil eden bir modelde zaman parametresini sikistirmak da cevre iletisiminde sorun yaratacak olmasindan kaynakli sorunlu.

Bizim için çok heyecan verici bir haberi paylaşmak istiyorum. Yeni çalışmamızda, insanlarda #Alzheimer riskini %71 azaltan bir #genetik değişimi ve bu değişimin etki mekanizmasını açığa çıkardık. Bu bulgu, milyonlarca insanı hastalıktan koruyabilir ve Alzheimer'ın önlenmesi ve tedavisinde yeni yollar sunabilir. @ColumbiaMed yapılan ve @Stanford , @Yale, @MayoClinic gibi enstitülerden araştırmacıların da dahil olduğu bu çalışma, hastalığı önleyebilecek genetik bir faktörün varlığını ortaya koyuyor. #Alzheimer #Bilim #Sağlık

2002 economic sciences laureate Daniel Kahneman has passed away aged 90.

He was awarded the prize for integrating insights from psychology into economics, especially human judgement and decision-making under uncertainty.

Have you wondered what the brain does while you’re daydreaming without sensory arousal? We found distinct neuronal ensembles distributed across 6 visual cortices that couple to ripples in either dorsal or intermediate hippocampus during these epochs. https://t.co/YulAREghVo 1/16

[@markandermann.bsky.social @andermann_mark]

Most studies characterize visual cortical neurons using stimulus-triggered responses, but the picture is quite different when you trigger on internally generated events such as hippocampal ripples.

Really fun collaboration with @HuijeongJeong, Min Whan Jung, and @vijay_mkn!

How does the brain select what to consolidate during sleep? New in @sciencemagazine , our work (https://t.co/9AqhbvNYc2) sheds light on the brain's mechanism for selective memory consolidation. 🧵👇1/n

We need to retain talented postdocs in academic science. I'm happy to say that @HHMINEWS has taken a big step forward this week.
$70,000
That's the new starting minimum salary for all postdocs employed in HHMI labs
