I couldn't find a tool to plot different #neuroimaging data in one consistent style, so I made one! Meet yabplot (yet another brain plot) - a #Python package for (sub)cortex & tracts.🧠
- Simple API
- Built-in atlases
- Custom atlas support

6/ This pattern suggests that flatter aperiodic exponents may reflect a marker of decrement in age-related memory performance, whereas steeper exponents, potentially reflecting an optimised E/I balance within neural circuits, may index a protective mechanism against age-related memory decline.

5/ However, those with average or lower exponents showed the typical pattern of poorer memory performance with advancing age.

4/ What we found: The aperiodic exponent moderates the link between age and memory. For those with a higher (steeper) exponent, age wasn't significantly associated with episodic or visual short-term memory performance.

3/ Specifically, we looked at individual alpha peak frequency (IAF) and the "aperiodic exponent" - a measure of the brain's "background noise" often linked to the balance of excitation and inhibition (E/I) in neural circuits.

2/ We studied 99 healthy adults (ages 50-84) using computerised CANTAB tasks to measure episodic, working, and visual short-term memory. We wanted to see how resting-state EEG markers relate to these different memory systems and age.

1/ 🧠 Is there a "hidden" brain signal that protects against age-related memory decline? Our new paper in @neurobiology-aging.bsky.social explores how periodic (oscillatory) and aperiodic (non-oscillatory) EEG activity may be a key biomarker for cognitive resilience in older adults. 🧵

Pretty much. The argument is not really about the brain,
it’s about what you consider “significant variance” lol

Hemispheric asymmetry of tau pathology is related to asymmetric amyloid deposition in Alzheimer’s Disease - Nature Communications Asymmetrical distribution of tau pathology in Alzheimer’s disease is linked to asymmetrical amyloid-beta deposition, not reduced brain connectivity, suggesting regional vulnerability plays a key role ...

🚨New paper alert! Our study led by @teanijarv.bsky.social
investigated why some individuals with Alzheimer’s disease (AD) develop hemispheric asymmetry in tau pathology and what drives this phenomenon.
Out now in Nature Communications! 🔗Full article: doi.org/10.1038/s414...

Yooooo love love love. Amazing work as always and indeed VERY COOL! 🧠✨

🧠✨How do we rebuild our memories? In our new study, we show that hippocampal ripples kickstart a coordinated expansion of cortical activity that helps reconstruct past experiences.

We recorded iEEG from patients during memory retrieval... and found something really cool 👇(thread)

Optimal dietary patterns for healthy aging - Nature Medicine In two longitudinal cohorts followed for 30 years, the associations of eight different dietary patterns with healthy aging—encompassing cognitive, physical and mental health—were studied, identifying food constituents linked to greater or lesser odds of healthy aging.

Eating a diet high in specific types of nutrients — including fruits, vegetables, whole grains, unsaturated fats, nuts, legumes, and low-fat dairy products — is associated with improved physical and mental health in older age, according to a study in Nature Medicine. #medsky 🧪

New research out in Psychophysiology (doi.org/10.1111/psyp...). The EEG aperiodic slope, thought to reflect cortical excitatory/inhibitory balance, was linked to temperament traits (surgency, regulation) in infancy and moderated associations between maternal anxiety/depression and infant regulation.
