A presynaptic phosphosignaling hub for lasting homeostatic plasticity.

recommendations! Published in 2022 at "Cell reports"

DOI: 10.1016/j.celrep.2022.110696

Abstract: Stable function of networks requires that synapses adapt their strength to levels of neuronal activity, and failure to do so results in cognitive disorders. How such homeostatic regulation may be implemented in mammalian synapses remains… read more here.

DOI: 10.1016/j.clinph.2018.01.060

Abstract: OBJECTIVE Homeostatic plasticity mechanisms regulate synaptic plasticity in the human brain. Impaired homeostatic plasticity may contribute to maladaptive synaptic plasticity and symptom persistence in chronic musculoskeletal pain. METHODS We examined homeostatic plasticity in fifty individuals… read more here.

DOI: 10.1016/j.neuron.2020.06.013

Abstract: In this issue of Neuron, Orr et al. (2020) identify an evolutionarily conserved mechanism of presynaptic homeostatic plasticity induced by ALS-like motor neuron degeneration, which maintains excitatory potentials until a threshold of synaptic loss is reached.… read more here.

recommendations! Published in 2020 at "Neurobiology of Learning and Memory"

DOI: 10.1016/j.nlm.2019.01.005

Abstract: To support computation the activity of neurons must vary within a useful range, which highlights one potential value of homeostatic plasticity. The interconnectedness of the brain, however, introduces the possibility that combinations of homeostatic mechanisms… read more here.

DOI: 10.1038/s41598-017-12972-6

Abstract: Central sensitization and network hyperexcitability of the nociceptive system is a basic mechanism of neuropathic pain. We hypothesize that development of cortical hyperexcitability underlying neuropathic pain may involve homeostatic plasticity in response to lesion-induced somatosensory… read more here.

recommendations! Published in 2018 at "Physical Review X"

DOI: 10.1103/physrevx.8.031018

Abstract: In vitro and in vivo spiking activity clearly differ. Whereas networks in vitro develop strong bursts separated by periods of very little spiking activity, in vivo cortical networks show continuous activity. This is puzzling considering… read more here.

recommendations! Published in 2023 at "Epilepsia"

DOI: 10.1111/epi.17500

Abstract: Homeostatic plasticity allows neural circuits to maintain an average activity level while preserving the ability to learn new associations and efficiently transmit information. This dynamic process usually protects the brain from excessive activity, like seizures.… read more here.

DOI: 10.1186/s13041-021-00783-w

Abstract: Homeostatic plasticity is necessary for the construction and maintenance of functional neuronal networks, but principal molecular mechanisms required for or modified by homeostatic plasticity are not well understood. We recently reported that homeostatic plasticity induced… read more here.

DOI: 10.3389/fncel.2021.685838

Abstract: In nature, animals need to adapt to constant changes in their environment. Learning and memory are cognitive capabilities that allow this to happen. Extinction, the reduction of a certain behavior or learning previously established, refers… read more here.
