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.
The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
Individual neurons can adjust the strength of their synapses by using spontaneous calcium influx through NMDA receptors to trigger the release of additional calcium from intracellular stores, which can in turn be used to regulate protein synthesis.
Computational model reveals how the fast exchange of neurotransmitter receptors between synapses induces a competition leading to a transient form of heterosynaptic plasticity and shaping the induction of homosynaptic plasticity.
Networks simulations and in vivo imaging suggest a stable backbone of stimulus representation formed by neurons with low population coupling, alongside a flexible substrate of neurons with high population coupling.
A large variety of spatial representations implied in rodent navigation could arise robustly and rapidly from inputs with a weak spatial structure, by an interaction of excitatory and inhibitory synaptic plasticity.
