How nerve cells flexibly adapt to acoustic signals
Nerve cells flexibly adapt to acoustic signals, research has shown. Depending on the input signal, neurons generate action potentials either near or far away from the cell body. Nerve cells ensure that the various kinds of input signals are optimally processed -- and thus allow us to perceive both small and large acoustic arrival time differences well, and thereby localize sounds in space.<img src="http://feeds.feedburner.com/~r/sciencedaily/~4/lA2Umz-bsEA" height="1" width="1"/>
