“…Neurophysiological studies using EEG and MEG have helped to clarify the temporal dynamics of the tongue SI (Ishiko et al, 1980; Altenmüller et al, 1990; Karhu et al, 1991; Nakamura et al, 1998; Maloney et al, 2000; Disbrow et al, 2003; Nakahara et al, 2004). The evaluation of time-locked EEG and MEG following somatosensory stimulation (i.e., somatosensory-evoked potentials, SEPs; somatosensory-evoked magnetic fields, SEFs) constitutes one of the most useful methods for investigating the human somatosensory system.…”

“…However, the response time to stimulation of the tongue ranges widely from 10 to 55 ms (Table 1). In addition, some studies reported activity in SI contralateral to the stimulation (Nakamura et al, 1998; Maloney et al, 2000; Nakahara et al, 2004), whereas others found activity in both SIs (Ishiko et al, 1980; Altenmüller et al, 1990; Karhu et al, 1991; Disbrow et al, 2003; Maezawa et al, 2008; Sakamoto et al, 2008a; Tamura et al, 2008). …”

“…Maloney et al (2000) used pairs of thin, stainless steel disk electrodes on modified mandibular or maxillary acrylic splints, similar to orthodontic retainers. The Mandibular splint electrodes were oriented to make contact with the under surface of the tongue along the course of the right and left lingual nerves and the maxillary splint electrodes were oriented to make contact with the hard palate bilaterally along the course of the palatine nerves.…”

We review research on somatosensory (tactile) processing of the tongue based on data obtained using non-invasive neurophysiological and neuroimaging methods. Technical difficulties in stimulating the tongue, due to the noise elicited by the stimulator, the fixation of the stimulator, and the vomiting reflex, have necessitated the development of specialized devices. In this article, we show the brain activity relating to somatosensory processing of the tongue evoked by such devices. More recently, the postero-lateral part of the tongue has been stimulated, and the brain response compared with that on stimulation of the antero-lateral part of the tongue. It is likely that a difference existed in somatosensory processing of the tongue, particularly around primary somatosensory cortex, Brodmann area 40, and the anterior cingulate cortex.

“…These experimental conditions were based on previous studies. [7][8][9][10] The patch was applied to the canine gingivobuccal fold for 5 minutes (Figure 2). After removal of the patch, the area was dried fully with air, an electrode was immediately placed on the area, and TSEP was measured.…”

We analyzed trigeminal somatosensory evoked potentials (TSEP) to the alveolar mucosa to investigate the efficacy of an amide local anesthetic, 2% lidocaine hydrochloride with 12.5 lg/mL epinephrine (Lido treatment) as a topical anesthetic. Eighteen consenting healthy adult volunteers were enrolled. A volume of 0.06 mL of Lido, 0.06 g of 20% benzocaine, or 0.06 mL of physiological saline (control) was instilled onto a hemostatic adhesive patch, which was then applied to the alveolar mucosa at the maxillary right canine for 5 minutes. An electrical stimulus approximately 5 times that of the sensory threshold was applied using a surface stimulation electrode. The trigeminal somatosensory evoked potential was recorded immediately, 5 minutes, and 10 minutes after removal of the patch. Positive P125 and P310 peaks and negative N100 and N340 peaks were observed as a result of the electrical stimulation. A significant decrease in the percentage change in amplitude of N100-P125 was observed in the Lido treatment immediately, 5 minutes, and 10 minutes after patch removal. In the Lido treatment, trigeminal somatosensory evoked potential amplitude at N100-P125 decreased significantly, suggesting that topical anesthesia produced by an amide local anesthetic may have a topical anesthetic effect as potent as that produced by an ester local anesthetic.

“…This method has high temporal resolution and allows for the scalp recording of neuronal activity that is time-locked to a sensory stimulus, yielding the sensory evoked potential. It has been shown that electrical and mechanical stimuli applied to the lips, buccal cavities, tongue, faucial arches, soft palate, nasal cavity, and nasopharynx will evoke a cortical sensory response (Fujiu et al, 1994; Maloney et al, 2000; Hummel et al, 2002; Gow et al, 2004; Nakahara et al, 2004; Yoshida et al, 2006). We have recently shown that air puffs applied to the posterior oropharyngeal wall will elicit a sensory evoked potential, termed the PSEP (pharyngeal sensory evoked potential), that is characterized by four component peaks: P1, N1, P2, N2, named for their polarity (positive or negative) and relative order (Wheeler-Hegland et al, in press).…”

Somatosensory evoked potentials provide a measure of cortical neuronal activation in response to various types of sensory stimuli. In order to prevent flooding of the cortex with redundant information various sensory stimuli are gated cortically such that response to stimulus 2 (S2) is significantly reduced in amplitude compared to stimulus 1 (S1). Upper airway protective mechanisms, such as swallowing and cough, are dependent on sensory input for triggering and modifying their motor output. Thus, it was hypothesized that central neural gating would be absent for paired-air puff stimuli applied to the oropharynx. Twenty-three healthy adults (18–35 years) served as research participants. Pharyngeal sensory evoked potentials (PSEPs) were measured via 32-electrode cap (10–20 system) connected to SynAmps2 Neuroscan EEG System. Paired-pulse air puffs were delivered with an inter-stimulus interval of 500 ms to the oropharynx using a thin polyethylene tube connected to a flexible laryngoscope. Data were analyzed using descriptive statistics and a repeated measures analysis of variance. There were no significant differences found for the amplitudes S1 and S2 for any of the four component PSEP peaks. Mean gating ratios were above 0.90 for each peak. Results supports our hypothesis that sensory central neural gating would be absent for component PSEP peaks with paired-pulse stimuli delivered to the oropharynx. This may be related to the need for constant sensory monitoring necessary for adequate airway protection associated with swallowing and coughing.
