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.
Pyramidal cells of the subiculum, a major output cell type of the hippocampus, can be deconstructed into distinct subtypes that exhibit a patchwork-like organization in space.

Sensory deprivation suppresses cortical responsiveness through a selective remodeling of excitatory and inhibitory microcircuit motifs, by simultaneously amplifying feedforward and suppressing feedback excitation.
The learning rate for novel spatial environments in model networks of place cells is determined by the product of the window for plasticity and the auto-correlation of place-cell activity.
