“…Multisensory convergence clearly does occur in numerous subcortical structures, including superior colliculus (Stein and Meredith, 1993), inferior colliculus , dorsal cochlear nucleus (Kanold and Young, 2001), and the reticular formation (Amassian and Devito, 1954;Bell et al, 1964). However, there remains a longstanding view that multisensory convergence in the neocortex is essentially a higher-order process, deferred until each unisensory bit is thoroughly processed through its specific sensory hierarchy (Jones and Powell, 1970).…”

Auditory Cortical Neurons Respond to Somatosensory Stimulation

The prevailing hierarchical model of cortical sensory processing holds that early processing is specific to individual modalities and that combination of information from different modalities is deferred until higher-order stages of processing. In this paper, we present physiological evidence of multisensory convergence at an early stage of cortical auditory processing. We used multi-neuron cluster recordings, along with a limited sample of single-unit recordings, to determine whether neurons in the macaque auditory cortex respond to cutaneous stimulation. We found coextensive cutaneous and auditory responses in caudomedial auditory cortex, an area lying adjacent to A1, and at the second stage of the auditory cortical hierarchy. Somatosensory-auditory convergence in auditory cortex may underlie effects observed in human studies. Convergence of inputs from different sensory modalities at very early stages of cortical sensory processing has important implications for both our developing understanding of multisensory processing and established views of unisensory processing.

“…Comparison with other mid-brain studies Other workers (Amassian & de Vito, 1954;Amassian & Waller, 1958;Bell et al 1954;Scheibel et al 1955) have estimated receptive fields and noted heterosensory convergence in the region to which the present article is devoted, though most of them have pooled results from anatomically less well defined areas of larger extent. Above all, it must be emphasized that different anaesthetic effects and experimental conditions (e.g.…”

“…The mid-brain reticular formation has been previously studied by a large number of workers (Amassian & de Vito, 1954;Amassian & Waller, 1958;Bell, Sierra, Buendia & Segundo, 1964;Bremer & Terzuelo, 1952; Mancia, Mechelse & Mollica, 1957; Morin, 1953, Scheibel, Scheibel, Mollica & Moruzzi, 1955;Starzl, Taylor & Magoun, 1951). We have chosen to examine it again under exactly the same conditions as those used in our previous study of the gigantocellular bulbar reticular formation (GC) (Bowsher, Mallart, Petit & Albe-Fessard, 1968), so as to be able to make valid comparisons between the two regions.…”
