Interactions between sensory pathways such as the visual and auditory systems are known to occur in the brain, but where they first occur is uncertain. Here, we show a novel multimodal interaction evident at the eardrum. Ear canal microphone measurements in humans (n = 19 ears in 16 subjects) and monkeys (n = 5 ears in 3 subjects) performing a sacc...

The inferior colliculus (IC) is a major processing center situated mid-way along both the ascending and descending auditory pathways of the brain stem. Although it is fundamentally an auditory area, the IC also receives anatomical input from non-auditory sources. Neurophysiological studies corroborate that non-auditory stimuli can modulate auditory...

... Gaze behavior is a form of active sensing; individuals shift their gaze 3-4 times per second both consciously and unconsciously to gain high resolution information about aspects of a visual scene [1], [2], [3], [4], [5]. Auditory stimuli and internal factors related to personal experience, such as memory, have also been shown to affect eye movements and visual perception [6], [7], [8], [9], [10]. Many researchers have analyzed gaze behaviors of individuals who identify as neurodivergent, and particularly with an autism spectrum condition (ASC) [11] noting differences in gaze behavior particularly in social settings [12], [13], [14], [15], [16], [17], [18]. ...
... Groh and Sparks,30 1992; Boucher et al., 2001;Metzger et al., 2004). Most previous work about how eye 31 movement information is incorporated into auditory processing has focused on cortical 32 and subcortical brain structures Sparks, 1984, 1987a, b;Russo and Bruce, 33 1994; Hartline et al., 1995;Stricanne et al., 1996;Cohen and Andersen, 2000;Groh et 34 al., 2001;Zella et al., 2001;Werner-Reiss et al., 2003;Fu et al., 2004;Populin et al., 35 3 2012; Caruso et al., 2021), but the recent discovery of eye-movement related eardrum 38 oscillations (EMREOs) (Gruters et al., 2018) suggests that the process might be 39 manifest much earlier in the auditory periphery. EMREOs can be thought of as a 40 biomarker of underlying efferent information impacting the internal structures of the ear 41 in association with eye movements. ...
... Nevertheless, consequences of hearing loss on executive functions and brain regions subserving executive function, such as the prefrontal cortex (PFC), have been suggested (Galloway et al., 2008;Ball et al., 2011;Kronenberger et al., 2013Kronenberger et al., , 2014Kral et al., 2016;Marschark et al., 2017). In this context, also the inferior colliculus (IC) of the auditory pathway is interesting, since this region is highly interconnected with sensory, motor, and cognitive networks (Gruters and Groh, 2012;Melo-Thomas and Thomas, 2015;Olthof et al., 2019;Cauzzo et al., 2022). ...
