Auditory Suppression

Behavioral disorders were a prominent clinical feature after the surgical treatment of an anterior communicating artery aneurysm rupture in a 44-year-old man. Callosal apraxia was associated with an alien hand. The latter remained 1 year after surgery while diagonistic apraxia disappeared after 3 months. Other callosal signs included left agraphia, tactile anomia and auditory suppression. MRI revealed posterior callosal infarction and a right frontal infarct. The association of diagonistic apraxia and alien hand is rarely reported.

The Brain

Songbirds use auditory feedback to maintain their own songs. Juveniles also memorize a tutor song and use memory as a template to make up their own songs through auditory feedback. A recent electrophysiological study revealed that HVC neurons respond to BOS playback only in low arousal, sleeping, or anesthetized conditions. One outstanding question is how does auditory suppression occur in the brain? Here, we determined how arousal affects auditory responses simultaneously in the whole brain and over the song neural circuit in Bengalese finches, using the immediate early gene egr-1 as a marker of neural activity. Our results showed that auditory responses in the low-arousal state were less susceptible to gating, which was also confirmed by gene expression, and that the suppression may be weaker than observed in previous zebra finch studies. This may be because the Bengalese finch is a domesticated species. In addition, our results suggest that information may flow from the MLd.I of the midbrain to higher auditory regions. Altogether, this study presents a new attempt to explore the auditory suppression network by simultaneously investigating the whole brain using molecular biology methods.

Normal Speech

A number of individuals complain of difficulties with speech recognition in noise in spite of normal hearing. This has prompted a search for disruptions in other areas of auditory processing that may account for these deficits. Two processes that may be related to speech recognition, auditory suppression and auditory enhancement, were evaluated in five listeners with normal speech recognition in noise (NSRN) and five listeners with reduced speech recognition in noise (RSRN). Although differences between the two groups were not observed for enhanced forward masking, significant differences were observed in two-tone suppression when the duration of the suppressor was varied. Those with RSRN showed greater suppression than those with NSRN when the suppressor onset preceded the masker onset.

Stimulation Of

Electrical stimulation of the auditory system results in auditory perception as well as auditory suppression. Historically, this is well documented. The recent application of advances of high technology and microsurgery of the ear have allowed basic science and clinical investigation to have access to electrical stimulation of the auditory system and its response. It is historically of great interest that such investigation in the past always involved attempts for evaluation and treatment for either auditory stimulation and/or auditory suppression. I believe the work of Aran (1981) reawakened recent interest in electrical stimulation of the auditory system for tinnitus suppression as well as auditory stimulation. Briefly, in his investigation of a deaf patient, he observed the following: (a) negative currents were more effective than positive currents for auditory stimulation; (b) positive current pulses reduced (suppressed) the intensity of tinnitus; (c) electrical stimulation in deaf patients by negative currents resulted in some sound perception. (In the congenitally deaf patients, it is difficult to evaluate the sensation produced); (d) the intensity of positive pulses necessary to suppress tinnitus is always higher than that of negative pulses resulting in auditory perception; (e) for positive pulses, the range between the threshold of tinnitus suppression and auditory perception when pulses of intermediate intensity are used, without inducing auditory perception, is wide enough to achieve total tinnitus suppression. (In other words, the current effective for electrical stimulation suppressing tinnitus is at a strength well below that producing auditory sensation); (f) negative electrical pulses can produce two different sounds-tinnitus and an auditory sensation; (g) electrical stimulation via the promontory and/or round window can be used both for auditory stimulation as well as for auditory suppression.
