Our paper is now in print in Nature @nature.com. If you're interested in local field potentials, especially #high-gamma activity, and/or #spikes, check it out! TL;DR: High gamma is not mainly filtered spikes, but mainly summed nearby PSPs. www.nature.com/articles/s41...

Active dissociation of intracortical spiking and high gamma activity - Nature

A brain–machine interface is used in monkeys to investigate the biophysical underpinnings of cortical high gamma-band activity, a signal that is often studied in the context of many brain functions.

Mental imagery and perception overlap within transmodal association networks

Anderson et al. map brain activity during cued imagination with individual-level precision fMRI and show that imagined scenes and inner speech recruit distinct networks whose engagement tracks self-reported vividness. Overlap with perception was mainly in association networks, rather than nearby sensory networks, suggesting that transmodal brain systems support mental imagery.

Thrilled and grateful to share our paper out today in @nature.com (rdcu.be/fbd7J). We used a brain machine interface (brain computer interface, #BCI) to causally test the origin of the high-gamma band of local field potentials #LFP. Results impact how we interpret many studies of #brain function

Widespread layoffs @ key federal health agencies like HHS, FDA, &NIH could delay progress on critical medical research, including Alzheimer's & cancer treatments. This puts future drug approvals & patient care at risk. The impact on public health is serious for you & your family. #HealthPolicy

1900 National Academy scientists sound the alarm: The current administration’s mismanagement and funding cuts to HHS and NIH will cost countless lives. Critical research into Alzheimer’s, cancer, and other diseases is being stalled, leaving you and your families to bear the devastating consequences.

The horror show continues at NIH I am hearing (reliably) that RIFs have started with entire institute Communication branches being terminated since their jobs not longer exist (reduction in force). But that is not all...

Analog computing with waves works—and it's vastly more energy-efficient than digital. Here, it's done with light, but all waves apply. Biology exploits useful things. Our brains constantly generate electric field waves. www.science.org/doi/10.1126/...

Enabling Optical Analog Computing with Metamaterials

The manipulation of light with structured materials could allow mathematical operations to be performed with compact optics. [Also see Report by Silva et al.]

NIH is effectively facing a cut. While the reduction is modest (0.6%: $280m CURES Act), inflation turns it into a ~5.6% real cut ($2.67b) compared to FY 2024’s purchasing power. The NIH would face reduced operational capacity unless offset by future adjustments or efficiencies.

IDC rates of 50-60% are not excessive; they reflect the real cost of supporting research. The new NIH proposal to cap IDCs at 15% would force institutions to either cut support services, subsidize from other sources, or reduce research activities—ending US leadership in healthcare R&D.

The NIH overhead cut doesn't just hurt universities. It's deadly to the US economy. The US is a world leader in tech due to the ecosystem that NIH and NSF propel. It drives innovation for tech transfer, creates a highly-skilled sci/tech workforce, and fosters academic/industry crossfertilization.

2. While NSF and NIH indeed have a mission to fund specific research innovations via grantmaking, they do a lot more than that. Their principal role is support a scientific ecosystem in the United States, that includes everything from education and training to infrastructure and communication.
