Mechanisms underlying directional selectivity for frequency-modulated sweeps in the inferior colliculus revealed by in vivo whole-cell recordings.

12 Oct 2009 Auditory neurons in the inferior colliculus (IC) show remarkable selectively in that they can distinguish between complex sounds that have identical spectral energy but different temporal structure, such as frequency modulations (FMs) that sweep ... Read more...

Astrocytes are poised for lactate trafficking and release from activated brain and for supply of glucose to neurons.

11 Aug 2009 Brain is a highly-oxidative organ, but during activation, glycolytic flux is preferentially up-regulated even though oxygen supply is adequate. The biochemical and cellular basis of metabolic changes during brain activation and the fate of lactate ... Read more...

GABA shapes selectivity for the rate and direction of frequency-modulated sweeps in the auditory cortex.

22 Jun 2009 In the pallid bat auditory cortex and inferior colliculus (IC), the majority of neurons tuned in the echolocation range is selective for the direction and rate of frequency-modulated (FM) sweeps used in echolocation. Such selectivity is shaped ... Read more...
