Synaptic scaling maintains motor output from the respiratory network of bullfrogs after months of inactivity in the winter, providing evidence for homeostatic plasticity in response to large ecologically relevant perturbations in neuronal activity.
Active dendritic processing enables an individual neuron to discriminate the spatial pattern of synaptic inputs, increasing neural and behavioral selectivity for escaping an impending threat.
Research in molecular ecology and evolution is increasingly utilizing the model plant Arabidopsis thaliana, placing a spotlight on its natural history.
In motor cortex pyramidal neurons, diverse task-related signals are distributed throughout the dendritic arbor and compartmentalized by dendritic distance and branching.
EphA signaling plays dual opposite roles on axon dynamics in neurons, so it inhibits and promotes axon growth through ligand binding and receptor processing, respectively.
RNAs enriched at cell protrusions are translated regardless of their location in the cytoplasm but are dynamically repressed in retracting protrusions and incorporated into heterogeneous RNA clusters.
Midbrain dopamine neurons use sophisticated secretory machinery to establish specialized sites for action potential-evoked release of dopamine from their cell bodies and dendrites.
Synaptophysins and gyrins dampen synaptic strength selectively at low frequencies, hinting that synaptic transmission may play a frequency filtering role in biological computation that is more general than currently envisioned.
