Most studies ask what #oxytocin does by giving it from the outside. But what happens when the brain releases its own? The answer: not a single "oxytocin circuit" but a profound reorganization of brain network dynamics (fMRI + ePhys) favoring salience-related states! 👉 tinyurl.com/mryc8rp6

How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation.

How are energy #metabolism pathways distributed across the #cortex? @alaindagher.bsky.social &co map five pathways in the human #brain, linking metabolic organization with brain structural & functional properties, as well as developmental dynamics @plosbiology.org 🧪 plos.io/4c1JVp8
Left:  Pathways involved in brain energy metabolism. Energy metabolism refers to processes involved in energy production from nutrient molecules. Glucose is the main energy source in the brain under normal physiological conditions. Glucose entering brain cells can be utilized in three parallel pathways. It can be processed through glycolysis to produce 2 ATP and 2 pyruvate molecules (blue). Lactate dehydrogenases catalyze the interconversion of lactate and pyruvate (purple). Pyruvate is transported into mitochondria, where it enters the TCA cycle to generate high-energy electron carriers NADH and FADH2 (green), driving the complete oxidation of glucose through the mitochondrial electron transport chain (red). Glucose entering the brain can also enter the PPP. PPP is an anabolic pathway that uses glucose to produce 5-carbon sugars and NADPH, an essential co-factor used in nucleotide and lipid biosynthesis (yellow). Glucose can also be stored in the form of glycogen via glycogen synthase, a process mainly active in astrocytes. Right: Energy pathway maps. Colors show z-scored mean expression values across all genes in each pathway. ppp, pentose phosphate pathway; tca, tricarboxylic acid cycle; oxphos, oxidative phosphorylation; lactate, lactate metabolism and transport.
