title: Lingual projections to the dorsal pons of the rat, studied by the field potential analysis.
abstract: Electrical stimulation of the chorda tympani (CT) of a rat produced a negative field potential with a peak latency of 8 msec localized in the parabrachial nucleus (PB) which may correspond to the pontine taste area. In contrast, stimulation of the glossopharyngeal nerve (GL) gave rise to no detectable negative field potential around the brachium conjunctivum. Stimulation of the lingual nerve (L) produced a large negative field potential with a similar latency, whose focus was found located just lateral to the focus of the negative potentials produced by CT stimulation.
