The brain’s #dynamics have been explained by a critically tuned model, but these miss rare reconfigurations. Audrey Sederberg explores a new @PLOSBiology.org study showing that modulation near a critical point can account for these events. #criticality Article plos.io/4yg9jzr Primer plos.io/4ygwABb
A schematic illustration of functional connectivity (FC) dynamics and modulation of global coupling strength.
A: synthetic activity over time representing seven regions of interest (ROI) from a hypothetical fMRI recording. Dot locations are for illustration only. B: the FC matrix estimated within limited time windows. The structure of the FC matrix changes over time, sometimes with high speeds (first two transitions) and sometimes low (third transition). C: the anatomical connectivity of this network is fixed but can be scaled up or down. Thicker lines represent stronger interactions. At smaller G, noise can cause the network to move between activity modes, generating different FC matrices and higher speeds between successive FCs. For high G, activity will collapse into one of the available network activity patterns, and FC changes more slowly. By construction in this example, the structural connectivity supports two patterns: one, with ROI (1, 2, 3) anti-correlated with ROI (4, 5, 6, 7); the other, with ROI (1, 3, 5, 7) anti-correlated with ROIs (2, 4, 6). Neuroimaging datasets have 10s to 100s of ROIs in typical parcellations and support many more stable FCs.

The DOGE firings have nothing to do with “efficiency” or “cutting waste.” They’re a direct push to weaken federal agencies perceived as liberal. This was evident from the start, and now the data confirms it: targeted agencies overwhelmingly those seen as more left-leaning. 🧵⬇️
Scatterplot titled “Empirical Evidence of Ideological Targeting in Federal Layoffs: Agencies seen as liberal are significantly more likely to face DOGE layoffs.”
	•	The x-axis represents Perceived Ideological Leaning of federal agencies, ranging from -2 (Most Liberal) to +2 (Most Conservative), based on survey responses from over 1,500 federal executives.
	•	The y-axis shows Agency Size (Number of Staff) on a logarithmic scale from 1,000 to 1,000,000.

Each point represents a federal agency:
	•	Red dots indicate agencies that experienced DOGE layoffs.
	•	Gray dots indicate agencies with no layoffs.

Key Observations:
	•	Liberal-leaning agencies (left side of the plot) are disproportionately represented among red dots, indicating higher layoff rates.
	•	Notable targeted agencies include:
	•	HHS (Health & Human Services)
	•	EPA (Environmental Protection Agency)
	•	NIH (National Institutes of Health)
	•	CFPB (Consumer Financial Protection Bureau)
	•	Dept. of Education
	•	USAID (U.S. Agency for International Development)
	•	The National Nuclear Security Administration (DOE), despite its conservative leaning (+1 on the scale), is an exception among targeted agencies.
	•	A notable outlier: the Department of Veterans Affairs (moderately conservative) also faced layoffs despite its size.

Takeaway:

The figure visually demonstrates that DOGE layoffs disproportionately targeted liberal-leaning agencies, supporting claims of ideological bias. The pattern reveals that layoffs were not driven by agency size or budget alone but were strongly associated with perceived ideology.
