Fujimoto et al. characterized the subcellular distribution of Kv4.2 potassium channels at synaptic level in the ventral division of the MGB (MGBv) of the mouse, since these channels may have an important role in shaping synaptic and spike waveforms while integrating the different temporal resolutions of inputs coming from the inferior colliculus (fast, high resolution responses) and auditory cortex (lower temporal resolution). [...]Alvarez-Munoz et al. reviewed the auditory efferent network, focusing on corticofugal and brainstem circuits involved in audition and cognition. The authors emphasize on behavioral studies performed in knock-out mice for the α9-nicotinic receptor subunit, which lacks cholinergic transmission between medial olivocochlear neurons and outer hair cells.
