“…The studies by van Dantzig et al (2008) and Vermeulen et al (2008) indicate the involvement of modality-specific sensory systems. Consistent with this claim is the finding in f MRI studies of activation of modality-specific brain areas while participants performed property verification or similar conceptual tasks (Goldberg et al, 2006;Martin et al, 1995).…”

“…This is in accordance with our previous findings, where the effect of BMI status was under consideration (Ghemulet et al, 2014). Semantic representations of taste-related words are closely related with certain brain regions responsible for gustatory processing and linked to activating taste domains (Barrós-Loscertales et al, 2012;Goldberg, Perfetti, & Schneider, 2006). It has been proposed that taste knowledge (words semantically related to taste) activate the orbitofrontal cortex (OFC).…”

Moderate alcohol consumption may be involved in cognitive feedback mechanisms (Hofmann & Friese, 2008), participants execute verbal fluency test (VFT) better (Cerhan et al., 1998) and there is positive association between sweet taste and excessive alcohol intake (Lange, Kampov-Polevoy, & Garbutt, 2010). We investigate the immediate pharmacological consequences of moderate to light alcohol consumption in verbal fluency and categorical sorting within the different taste domains (i.e. sweet, salty, sour and bitter). Our hypothesis is that subjects under the influence of light to moderate alcohol will produce more items in the sweet domain. 53 healthy adults had moderate alcohol consumption and were compared in two semantic tasks to 53 adults, who did not drink alcohol. Mann-Whitney U tests showed that the total number of clusters, switches, and repetitions were equal between the two groups in all taste domains (p-values: .211, .401, and .684 respectively). The number of responses in the alcohol group generated more disinhibiting intrusive words during the VFTs as compared to the control group (p-value: <.001). VFTs and the order of taste preference in the card-sorting task showed positive correlation and agreement. Light to moderate alcohol did not affect verbal fluency. However, participants under the influence of alcohol generated significantly more errors in the VFTs that were emotionally laden. This corroborates with research that certain emotions are innervated with taste domains. This leaves open question about the effects of alcohol on decision making in eating and executive functions as they relate to lexical representations.

“…This region contributes to the processing of complex sounds including human voices (Belin et al, 2000;Specht and Reul, 2003) and is activated during sound recognition (Lewis et al, 2004), episodic recall of sounds (Wheeler et al, 2000), and music imagery (Zatorre et al, 1996;Kraemer et al, 2005). Activity in pSTG/MTG was also observed for decisions on acoustic object attributes (Kellenbach et al, 2001;Goldberg et al, 2006) and during recognition of novel objects for which acoustic attributes were learned in a preceding training phase (James and Gauthier, 2003). Patients with a lesion in this area exhibit sound recognition deficits (Clarke et al, 2000).…”

Traditionally, concepts are conceived as abstract mental entities distinct from perceptual or motor brain systems. However, recent results let assume modality-specific representations of concepts. The ultimate test for grounding concepts in perception requires the fulfillment of the following four markers: conceptual processing during (1) an implicit task should activate (2) a perceptual region (3) rapidly and (4) selectively. Here, we show using functional magnetic resonance imaging and recordings of event-related potentials, that acoustic conceptual features recruit auditory brain areas even when implicitly presented through visual words. Fulfilling the four markers, the findings of our study unequivocally link the auditory and conceptual brain systems: recognition of words denoting objects, for which acoustic features are highly relevant (e.g.,"telephone"), ignited cell assemblies in posterior superior and middle temporal gyri (pSTG/ MTG) within 150 ms that were also activated by sound perception. Importantly, activity within a cluster of pSTG/MTG increased selectively as a function of acoustic, but not of visual and action-related feature relevance. The implicitness of the conceptual task, the selective modulation of left pSTG/MTG activity by acoustic feature relevance, the early onset of this activity at 150 ms and its anatomical overlap with perceptual sound processing are four markers for a modality-specific representation of auditory conceptual features in left pSTG/ MTG. Our results therefore provide the first direct evidence for a link between perceptual and conceptual acoustic processing. They demonstrate that access to concepts involves a partial reinstatement of brain activity during the perception of objects.
