Resting-state capillary blood flow and oxygenation are more homogeneous in the deeper cortical layers, underpinning an important mechanism by which the microvascular network adapts to an increased local oxidative metabolism.
A potent and selective DYRK2 inhibitor has been developed and used as a chemical tool to reveal eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1) and stromal interaction molecule 1 (STIM1) are new substrates for DYRK2.
Well-controlled psychological experiments show that there is little overlap in how humans and convolutional networks classify adversarial images, highlighting the problem of using CNNs as models of human vision.
Dimensionality reduction approaches on functional MRI data reveal that human reward-based motor learning emerges from dynamic changes in functional brain network interactions among sensorimotor, attention, and default mode networks.
Hippocampal and prefrontal neuronal populations form slow behavioral-timescale (~seconds) and fast cognitive-timescale (~100 ms) sequential activity patterns as theta and replay sequences, which play distinct yet cooperative roles in memory-guided decision-making.
In astrocytes, there exists an intrinsic spatial threshold of subcellular calcium levels that triggers an astrocyte calcium surge throughout the cell, demonstrating cellular astrocyte calcium integration of time and space.

A novel FRET approach suggests that the intracellular termini of acid-sensing ion channel 1a do not form a complex at rest requiring a new hypothesis for ASIC1a involvement in stroke.
One hundred one high-quality drosophilid genomes are released, along with low-cost assembly workflows, as an open community resource for studying genetics, ecology, and evolution in this important model system.

A new analysis algorithm (DISC) enables accurate analysis of data from high-throughput single-molecule paradigms and reveals a non-cooperative binding mechanism of cyclic nucleotide-binding domains from HCN ion channels.
