“…The literature suggests that the neural signals from the auditory pathway are significantly modulated by the visual system and the somatosensory system. Additional investigations showed that this modulation occurs at a minimum of three different locations in the ascending auditory pathway: Inferior colliculus, Medial Geniculate Body and Auditory Cortex [45]. A hallmark investigation concurring with past research showed that Cross-modal mapping of low luminescence to low pitch sounds and high luminescence to high pitch sounds may have evolved before humans.…”

Humans have the ability to think in abstract ways. Experiments over the last 90 years have shown that stimuli from the external world can be evaluated on an abstract spectrum with 'Kiki' on one end and 'Bouba' on the other. People are in concordance with each other with respect to calling a jagged-edgysharp bordered two dimensional shape 'Kiki' and a curvy-smooth-round two dimensional shape 'Bouba'.. The proclivity of this correspondence is ubiquitous. Moreover, the Kiki-Bouba phenomenon seems to represent a non-arbitrary abstract connection between 2 or more stimuli. Studies have shown that crossmodal associations between and withinaudioception, opthalmoception, tactioception and gustatoception can be demonstrated by using Kiki-Bouba as a cognitive 'convergence point'. This review includes a critical assessment of the methods, findings, limitations, plausible explanations and future directions involving the Kiki-Bouba effect. Applications include creatingtreatments and training methods to compensate for poor abstract thinking abilities caused by disorders like schizophrenia and autism, for example. Continuing research in this area would help building a universal model of consciousness that fully incorporates cross-sensory perception at the biological and cognitive levels.

“…Integration of auditory and somatosensory afferent projections occurs in peripheral brain structures as early as the CN, where projections from the AN and trigeminal and dorsal column ganglia and brain stem nuclei converge [95, 96]. These projection neurons terminate primarily on the CN granule cells, whose parallel-fiber axons terminate on the apical dendrites of DCN fusiform cells [97–99].…”

Maladaptive plasticity in tinnitus — triggers, mechanisms and treatment

Tinnitus is a phantom auditory sensation that reduces quality of life for millions worldwide and for which there is no medical cure. Most cases are associated with hearing loss caused by the aging process or noise exposure. Because exposure to loud recreational sound is common among youthful populations, young persons are at increasing risk. Head or neck injuries can also trigger the development of tinnitus, as altered somatosensory input can affect auditory pathways and lead to tinnitus or modulate its intensity. Emotional and attentional state may play a role in tinnitus development and maintenance via top-down mechanisms. Thus, military in combat are particularly at risk due to combined hearing loss, somatosensory system disturbances and emotional stress. Neuroscience research has identified neural changes related to tinnitus that commence at the cochlear nucleus and extend to the auditory cortex and brain regions beyond. Maladaptive neural plasticity appears to underlie these neural changes, as it results in increased spontaneous firing rates and synchrony among neurons in central auditory structures that may generate the phantom percept. This review highlights the links between animal and human studies, including several therapeutic approaches that have been developed, which aim to target the neuroplastic changes underlying tinnitus.

“…This type of tinnitus derives from complex somatosensory-auditory interactions and cross-modal mechanisms that mainly arise from musculoskeletal anatomical regions such as the temporomandibular joint (TMJ), craniocervical junction, cervical vertebrae, and neck and shoulder muscles (NECK) [Chan and Reade, 1994;Levine et al, 2003;Abel and Levine, 2004;Tullberg and Ernberg, 2006;Björne, 2007;Bernhardt et al, 2011;Vielsmeier et al, 2012;Buergers et al, 2014]. Animal studies have shown that projections from the auditory nerve and trigeminal and dorsal column ganglia and brainstem nuclei integrate in the cochlear dorsal nucleus [Haenggeli et al, 2005;Zhan et al, 2006;Dehmel et al, 2008;Wu et al, 2014]; furthermore, nonacoustic stimulation can modulate both the firing rates and temporal response patterns to the acoustic stimulation in the inferior colliculus, which receives inputs from the dorsal cochlear nucleus and the somatosensory nuclei [Zhou and Shore, 2006].…”

Somatosensory Tinnitus: Correlation between Cranio-Cervico-Mandibular Disorder History and Somatic Modulation

et al. 2016

In a subpopulation of patients, tinnitus can be modulated by movements of the jaw or head and neck due to complex somatosensory-auditory interactions. In some of these subjects, tinnitus could be related to an underlying temporomandibular (TMJ) or craniocervical (NECK) dysfunction that, if correctly identified, could streamline treatment and increase chances of tinnitus improvement. However, it is still unclear whether somatic modulation of tinnitus could be used as a screening tool for identifying such patients. In this study, we included 310 tinnitus patients with normal hearing, no psychiatric comorbidities, and a positive history of TMJ and/or NECK dysfunction and/or a positive modulation of tinnitus to evaluate the characteristics of somatic modulation, investigate the relationship between positive history and positive modulation, and identify factors most strongly associated with somatic modulation. Tinnitus modulation was present in 79.67% of the patients. We found a significant association within the same subjects between a positive history and a positive tinnitus modulation for the same region, mainly for TMJ in unilateral tinnitus patients and for TMJ + NECK in bilateral tinnitus patients. A strong correlation between history and modulation in the same somatic region within the same subgroups of subjects was also identified. Most TMJ maneuvers resulted in an increased loudness, while NECK maneuvers showed an increase in tinnitus loudness in about 59% of cases. High-pitched tinnitus and male gender were associated with a higher prevalence of modulation; no differences were found for tinnitus onset, Tinnitus Handicap Inventory score, and age. In this paper, we report a strong association between history and modulation for the same regions within the same patients; such an association should always be investigated to improve chances of a correct diagnosis of somatosensory tinnitus.
