Inhibition enhances the spatial specificity of high calcium influx for cooperatively stimulated synapses, suggesting that inhibitory inputs may regulate both synapse-specific and heterosynaptic plasticity to support learning and memory.

FIB-SEM is used to identify comprehensively and reconstruct 192 neurons and their complete connectome for glomerulus VA1v of the Drosophila antennal lobe, in particular to reconstruct its local interneurons.

Motor axons undergo dynamic branch-specific changes for weeks before complete neuronal degeneration in a model of amyotrophic lateral sclerosis, highlighting the importance of peripheral factors, intrinsic and extrinsic to motoneurons.

The transcription factor CrebB mediates long-term memory formation in different neurons within the mushroom body learning circuit, including mushroom body intrinsic and output neurons but not dopaminergic input neurons.
Whole-brain radiotherapy, but not glioma growth in distal region from the hippocampus, results in impaired recognition memory, which can be prevented by CSF-1R inhibitor-mediated microglia depletion.
Defects in synapse regeneration limit functional circuit recovery after nerve injury by misdirecting information via ectopic dendritic synapses, and also by functional and molecular deficits in reformed axonal synapses.

Local presynaptic protein synthesis occurring at established nerve terminals in the mammalian brain provides a mechanism for rapidly controlling or restoring presynaptic proteins that affect neurotransmitter release and presynaptic efficiency.
Serially remembered items are successively reactivated during memory maintenance in the human brain, and replay profiles, temporally compressed and reverse in order, are associated with recency effect in behavioral performance.
