title: 2-Deoxyglucose accumulation parallels extracellularly recorded spike activity in the avian auditory neostriatum.
abstract: In a combined 2-deoxyglucose (2-DG) and electrophysiological study, the congruence between metabolic activity and extracellularly recorded spike activity patterns has been examined in the auditory cortex analogue, field L, of chicks. Using tone stimuli we demonstrate a match of stripes of 2-DG labeling to electrode tracks yielding neurons with the same best frequency. Since 2-DG activity is thought to reflect chiefly input activity of neurons there appears to be a close input-output link for tone responses in field L.
