“…Differences in the connectivity patterns between anterior and posterior areas are consistent with the presence of functionally distinct processing streams. Given the specificity with which visual cortical fields innervate the auditory cortex (Bizley et al, 2007a), it seems likely that, as in the monkey (Hackett et al, 1999; Romanski et al, 1999), distinct differences may exist in the projections from the ferret auditory cortex to prefrontal and parietal areas, although this remains to be tested. Finally, the convergence and divergence of connections found throughout the auditory cortex suggest that behaviorally relevant information can be processed in parallel, providing a potential substrate for compensatory plasticity when specific cortical fields are removed or inactivated for prolonged periods.…”

Despite numerous studies of auditory cortical processing in the ferret (Mustela putorius), very little is known about the connections between the different regions of the auditory cortex that have been characterized cytoarchitectonically and physiologically. We examined the distribution of retrograde and anterograde labeling after injecting tracers into one or more regions of ferret auditory cortex. Injections of different tracers at frequency‐matched locations in the core areas, the primary auditory cortex (A1) and anterior auditory field (AAF), of the same animal revealed the presence of reciprocal connections with overlapping projections to and from discrete regions within the posterior pseudosylvian and suprasylvian fields (PPF and PSF), suggesting that these connections are frequency specific. In contrast, projections from the primary areas to the anterior dorsal field (ADF) on the anterior ectosylvian gyrus were scattered and non‐overlapping, consistent with the non‐tonotopic organization of this field. The relative strength of the projections originating in each of the primary fields differed, with A1 predominantly targeting the posterior bank fields PPF and PSF, which in turn project to the ventral posterior field, whereas AAF projects more heavily to the ADF, which then projects to the anteroventral field and the pseudosylvian sulcal cortex. These findings suggest that parallel anterior and posterior processing networks may exist, although the connections between different areas often overlap and interactions were present at all levels.

“…In the present sample, ESM demonstrated SSMA (or supplementary negative motor area)-type responses in most of the frontal P50max-sites. None of these areas is strictly "sensory" in nature, but there is evidence from animals and humans that there are significant connections between auditory and lateral and medial frontal cortices that may become active within 100 ms after an auditory stimulus (Romanski, 1999;Barbas, 1999;Picton, 1999). As for the SSMA proper, this area is known for its mixed somatosensory and motor representations despite its frontal location (Lim, 1994).…”

The filtering of sensory information, also referred to as "sensory gating", is impaired in various neuropsychiatric diseases. In the auditory domain, sensory gating is investigated mainly as a response decrease of the auditory evoked potential component P50 from one click to the second in a double click paradigm. In order to relate deficient sensory gating to anatomy, it is essential to identify the cortical structures involved in the generation of P50. However, the exact cerebral topography of P50 gating has remained largely unknown as yet. In a group of 17 patients with drug-resistant focal epilepsy, P50 was recorded invasively via subdural electrodes, and the topography of functionally indispensable ("eloquent") cortices was obtained by electrical stimulation mapping. These eloquent areas were involved in language, motor, and sensory functions. P50 could be identified in 13 patients in either temporal (n = 8) or midfrontal sites (n = 5). There were 6 occurrences (in 5 patients) of overlap of sites with maximal P50 responses and eloquent areas. Those were auditory (n = 1), supplementary sensorimotor (n = 3), primary motor (n = 1), and supplementary negative motor (n = 1). Results suggest that the early stage of sensory gating already involves a top-down modulation of sensory input by frontal areas.

“…These connections are also suggested to be topographic in nature. In monkeys, the rostral and orbital PFC (areas 10, 12, 13, 46 rostral) are connected with rostral belt and parabelt auditory cortex, while the caudal prefrontal regions (areas 8a, 12, 46 caudal) receive connections from the caudal belt and parabelt auditory cortex [Plakke and Romanski, 2014; Romanski et al, 1999]. …”

“…There is, by contrast, a wealth of neuroimaging studies providing evidence that the human frontal lobe is active during general auditory tasks [Alain et al, 2001; Arnott et al, 2004; Gaab et al, 2003; Kiehl et al, 2001; Koelsch et al, 2009; Muller et al, 2001; Platel et al, 1997; Rämä et al, 2004]. Neurophysiological and neuroanatomical findings in non‐human primates show that both dorsolateral and ventral PFC is reciprocally interconnected with auditory regions in the temporal cortex [Hackett et al, 1999; Plakke and Romanski, 2014; Romanski et al, 1999]. The frontal reading activation overlaps the tonotopic maps in the region, perhaps for a similar reason as for the retinotopic map overlap (e.g., memory allocation using topological maps as pointer buffers).…”

Areas activated during naturalistic reading comprehension overlap topological visual, auditory, and somatotomotor maps

Cortical mapping techniques using fMRI have been instrumental in identifying the boundaries of topological (neighbor‐preserving) maps in early sensory areas. The presence of topological maps beyond early sensory areas raises the possibility that they might play a significant role in other cognitive systems, and that topological mapping might help to delineate areas involved in higher cognitive processes. In this study, we combine surface‐based visual, auditory, and somatomotor mapping methods with a naturalistic reading comprehension task in the same group of subjects to provide a qualitative and quantitative assessment of the cortical overlap between sensory‐motor maps in all major sensory modalities, and reading processing regions. Our results suggest that cortical activation during naturalistic reading comprehension overlaps more extensively with topological sensory‐motor maps than has been heretofore appreciated. Reading activation in regions adjacent to occipital lobe and inferior parietal lobe almost completely overlaps visual maps, whereas a significant portion of frontal activation for reading in dorsolateral and ventral prefrontal cortex overlaps both visual and auditory maps. Even classical language regions in superior temporal cortex are partially overlapped by topological visual and auditory maps. By contrast, the main overlap with somatomotor maps is restricted to a small region on the anterior bank of the central sulcus near the border between the face and hand representations of M‐I.
