Local field potentials and single-neuron activity in the temporal cortex of a unanesthetized cat were synchronously averaged over its respiratory cycle. Differential recordings were performed using paired microelectrodes placed in the primary auditory area and in two secondary areas located anterior and posterior to it. The respiratory rhythm was most clearly represented in the anterior secondary auditory area, presumably situated within the anterior ectosylvian sulcus. In most recording sites within this area, pronounced changes in local potential amplitude occurred near the moment of maximal diaphragmatic displacement during inspiration. The activity of some neurons responsive to sound stimuli could also be modulated by the respiratory cycle. In the primary auditory area and in the posterior secondary zone, synchronization with respiration was considerably weaker and was usually manifested as a small deviation of the local potential from its mean level occurring near the point of maximal inspiration. In several cases, the polarity of this deviation changed with minor shifts of the recording site. The results suggest a possible role of interactions between exteroceptive and interoceptive processes in the cerebral cortex in the formation of primary consciousness.

Key words: local field potentials, respiration, brain–body interaction, consciousness, auditory cortex, neurons
