Activity-dependent sensitivity of proprioceptive sensory neurons in the stick insect femoral chordotonal organ.

abstract：:The structure of dendritic spines is highly plastic and can be modified by neuronal activity. In addition, there is evidence that spine head size correlates with the synaptic α-amino-3-hydroxy-5-methylisoxazole propionic acid (AMPA) receptor (AMPAR) content, which suggests that they may be coregulated. Although there ...
