Age-dependent actions of dopamine on inhibitory synaptic transmission in superficial layers of mouse prefrontal cortex.

abstract：:In the cochlear nucleus (CN) of awake mustached bats, single- and two-tone stimuli were used to examine how responses in major CN subdivisions contribute to spectrotemporal integrative features in the inferior colliculus (IC). Across CN subdivisions, the proportional representation of frequencies differed. A striking ...
