Abstract

Neuronal dendrites are not passive cables, but whether their excitability contributes to computation at the cell’s soma has been uncertain; by observing and interfering with dendritic ‘spikes’ during sensory stimulation, it is now shown that active dendritic processing enhances somatic orientation selectivity, a fundamental brain computation.
