Neural energy metabolism encodes directed communication across the human cortex

The paper uses energy metabolism to infer directed communication patterns in the human cortex, showing sensory systems drive higher-order networks and default mode networks act as receivers.

The blueprint of human functional architecture shifts from cognition to anatomy during perturbations of consciousness

This study shows that cognitive co-activation dominates fMRI synchrony in the awake brain but is replaced by anatomical and molecular constraints during consciousness perturbations.

Total cerebral blood volume changes drive macroscopic cerebrospinal fluid flux in humans

Comprehensive profiling of anaesthetised brain dynamics across phylogeny

This study profiles neural dynamics across species during anaesthesia, finding conserved dynamical changes and linking them to molecular mechanisms.

Region-specific uncoupling of oxygen and glucose metabolism in the human cortex during visual stimulation

This study uses combined PET/MR imaging to show that visual stimulation in humans increases glucose metabolism more than oxygen consumption in visual regions, while other cortical areas show oxidative downregulation.

An energy costly architecture of neuromodulators for human brain evolution and cognition

The paper investigates the energetic costs of neuromodulator signaling in the human brain and finds that evolutionarily novel connections have higher energetic costs than sensory-motor pathways.

General anaesthesia reduces the uniqueness of brain connectivity across individuals and across species

This study shows that general anaesthesia reduces the uniqueness of human brain connectivity both between individuals and across species.

Mapping Pharmacologically-induced Functional Reorganisation onto the Brain's Neurotransmitter Landscape

This study maps how pharmacological drugs alter brain function by linking neurotransmitter receptor distribution with drug-induced changes in functional MRI connectivity.

Spatial signatures of anesthesia-induced burst-suppression differ between primates and rodents

This study identifies species-specific fMRI signatures of anesthesia-induced burst-suppression in primates and rodents, showing differences in brain regions involved.
