🧠 Cognitive Brain Dynamics Lab Seminar | Tomorrow at 12 PM!
We're thrilled to welcome Dr. Sarthak Chandra (ICTS & NCBS) for a talk on "Episodic and Associative Memory from Spatial Scaffolds in the Hippocampus."
Dr. Chandra is a Murty Science Fellow at @ictstifr and a Faculty Associate at the @NCBS_Bangalore and a former @MIT @mitbrainandcog researcher (w/Ila Fiete) @FieteGroup, working on the functional architecture of hippocampal circuits.
Open to all!

【起きたまま睡眠!?】眠らなくても、睡眠中と同じ脳活動パターンを人工的に作り出せば、あたかも睡眠をとったかのように脳がリフレッシュ（睡眠圧が低下し記憶力も回復）するそうです。マウスでの実証。今日の『ネイチャー神経科学』誌より→ nature.com/articles/s41593-0…

Ever notice emotions hit harder with age? Our lab's new brain-imaging study reveals that older adults handle suspense, fear & surprise less steadily than younger people. Thrilled to see it featured in @NatureInd 🧠 Grateful @sahanaghosh8 covered it. Wonderful article and aptly summarised our work👇

Topographic structure and function of locus coeruleus norepinephrine neurons
This preprint investigates the organization of locus coeruleus noradrenaline (LC-NE) neurons, which are traditionally viewed as a global brain-wide arousal system.
Using mice, the researchers combined:
anatomical tracing,
gene-expression analysis,
morphology reconstruction,
and neural activity recordings.
They found that LC-NE neurons are not homogeneous. Instead, neurons in different spatial regions of the LC showed:
distinct projection targets across the brain,
different molecular identities,
different cellular morphologies,
and different activity patterns during behavior.
Some subpopulations were more strongly linked to learning, behavioral flexibility, and context-dependent processing.
The study argues that the locus coeruleus is organized more like a structured functional map than a single diffuse neuromodulatory broadcaster. This suggests that noradrenaline signaling may provide targeted, specialized modulation to different brain systems depending on behavioral demands.

Recent studies have revealed the synchronization of neuromodulators including norepinephrine, serotonin, acetylcholine, dopamine, and histamine during sleep.
A new #ScienceReview explores what potential role the synchronization of these oscillations may play in health. scim.ag/4ve9ObR

7/8 The impactful finding: medial-frontal beta power during encoding was the key predictor of memory errors — but only in the externally focused group.
In the self-reflection group? Beta's protective effect on memory was completely disrupted.

8/8 TL;DR: When you're thinking about yourself — even briefly — your brain literally rewires how it encodes the world around you. Beta oscillations that normally protect working memory get overridden.
Next time you zone out in a meeting, now you know exactly which brain wave is responsible 😅

Part 9 - The Pattern Emerges (Figure 6, Part 2)
Think of it like blurred vision for emotions:
Increased uncertainty → Adjacent emotions blend (anger/fear), but distant ones stay separate (anger/happiness).
Neural volatility creates systematic distortions in emotional space—not random noise!

Part 10 - The Big Picture & Impact
🎯 TAKEAWAYS:
Neural volatility reveals aging signatures invisible to traditional measures
OFC shows heightened uncertainty in affective inference
This may be an ADAPTIVE response to aging
Naturalistic paradigms (movies!) unlock real-world brain dynamics

🧠 NEW PAPER ALERT in @CerebralCortex! from Cognitive Brain Dynamics Lab
@iitjodhpur @DBT_NBRC @DBTIndia @EduMinOfIndia @MoHFW_INDIA We discovered how aging changes emotional brain processing during movie-watching. Spoiler: It's not about average activity—it's about VOLATILITY.
Huge thanks to first author @gargi_4 this study part of her final PhD thesis work with amazing co-authors @FahdYazin, @ArpanBanerjee, and the entire team at NBRC & IIT Jodhpur!

Part 8 - Beyond Movies: Emotion Recognition (Figure 6, Part 1)
Does this extend to other tasks? We tested facial emotion recognition (Happy, Sad, Anger, Fear, Disgust, Surprise).
Older adults:
📊 Higher variability in accuracy (SD: 17.44 vs 11.08, P<0.0001)
🔀 "Spillover" between ADJACENT emotions (Fear↔Surprise, Anger↔Disgust)

Part 7 - Neural State Transitions (Figure 5, Part 2)
Model prediction: More uncertainty → More state transitions
We tested with Hidden Markov Models:
✅ Young: Stable OFC states
✅ Older: Rapid, frequent transitions
Predictions matched neural data! Control (visual cortex): No difference between groups.
