Neuroscientists at Goethe University, Frankfurt have discovered a feedback loop that modulates the receptivity of the auditory cortex to incoming acoustic signals when bats emit echolocation calls. In a study published in the journal Nature Communications, the researchers show that information transfer in the neural circuits involved switched direction in the course of call production. It seems likely that this feedback prepares the auditory cortex for the expected echoes of the emitted calls. The researchers interpret their findings as indicating that the importance of feedback loops in the brain is currently still underestimated.
