A simple model of active transport in neurons allows intracellular cargo to find sites of demand using only local signals, but predicts long delays in distributing cargo throughout a dendritic tree.

In mouse models of Huntington's disease, the subthalamic nucleus, which suppresses movements, also exhibits impaired glutamate homeostasis, NMDA receptor-dependent mitochondrial oxidant stress, firing disruption, and 30% neuronal loss.
Phase-locking of hippocampal theta and gamma waves has been proposed to support memory formation, but an analysis using robust statistical methods finds no convincing evidence for the phenomenon.

Connectomic analysis demonstrates that a brain circuit, that may be conserved between flies and mammals, uses both fast synaptic transmission as well as peptidergic neuromodulation to connect chemosensory and endocrine systems.
Synapse-specific genetic manipulations show that distinct GABAergic inputs are differentially recruited to encode motion direction in the retina in a stimulus-dependent manner.
Crystal structures of a mammalian P2X7 receptor and structure-based functional studies reveal a novel drug-binding site and subtype-specific conformational rearrangements required for channel opening.
Filamin, by recruiting a signaling complex to the postsynapse, orchestrates the correct formation and growth of postsynaptic membranes and localization of glutamate receptor subunits.

Structural, biophysical, and functional analyses reveal that mutations in TREM2 trigger either misfolding or reduced binding to cell-surface glycosaminoglycans, which segregate with neurodegenerative disease link and highlight a functional surface linked to the pathogenesis of Alzheimer's disease.
