“…Analysis of neural firing when rats revisited arms that they had already retrieved chocolate milk from showed an absence of the postencounter effect in most Such data suggest that the sensory or motor consequences of drinking may play an important role in the coding of postencounter neurons during this navigational task. Activity of amygdala neurons to food or liquid reward has been documented previously in the monkey (Nishijo et al, 1988b;Sanghera et al, 1979) and the rat (Muramoto et al, 1993) during sensory discrimination, and it is known that the amygdala receives extensive inputs from olfactory and gustatory sensory areas (for reviews, see Amaral, Price, Pitkanen, & Carmichael, 1992;De Olmos, Alheid, & Beltramino, 1985; see also Luskin & Price, 1983;Ottersen, 1982;Turner & Herkenham, 1991).…”

Previous research has shown that spatial, movement, and reward information is integrated within the ventral striatum (VS). The present study examined the possible contribution of the basolateral nuclei of the amygdala (BLA) to this interaction by examining behavioral correlates of BLA neurons while rats performed multiple memory trials on an 8-arm radial maze. Alternate arms consistently held 1 of 2 different amounts of reward. Recorded cells were correlated with motion, auditory input, space, and reward acquisition. Reward-related units were found that anticipated reward encounter, that responded during reward consumption, and that differentiated between high and low reward magnitude. This is consistent with the hypothesis that BLA neurons may provide the VS with reward-related information that could then be integrated with spatial information to ultimately affect goal-directed behavior. Past research into the role of the amygdala in animal behavior has demonstrated that it is an important substrate for the association of cues with their affective significance.

“…The insula receives afferents from nuclei within the basolateral complex of the amygdala and the insula projects to other amygdaloid areas such as the medial and central nuclei (Mufson et al, 1981;Amaral and Price, 1984;Nishijo et al, 1988). Given that the basolateral amygdala is involved in fear conditioning or the emotional labeling of an event (Olsson and Phelps, 2007;Davis et al, 2008), it might well be that the insula's connectivity with the amygdala serves to associate vocal communication sounds with emotions.…”

Human imaging studies implicate the insular cortex in processing complex sounds and vocal communication signals such as speech. In addition, lesions of the insula often manifest as deficits in sound or speech recognition (auditory agnosia) and speech production. While models of acoustic perception assign an important role to the insula, little is known about the underlying neuronal substrate. Studying a vocal primate, we identified a predominantly auditory region in the caudal insula and therein discovered a neural representation of conspecific communication sounds. When probed with natural sounds, insula neurons exhibited higher response selectivity than neurons in auditory cortex, and in contrast to these, responded preferentially to conspecific vocalizations. Importantly, insula neurons not only preferred conspecific vocalizations over a wide range of environmental sounds and other animal vocalizations, but also over acoustically manipulated versions of these, demonstrating that this preference for vocalizations arises both from spectral and temporal features of the sounds. In addition, individual insula neurons responded highly selectively to only a few vocalizations and allowed the decoding of sound identity from single-trial responses. These findings characterize the caudal insula as a selectively responding auditory region, possibly part of a processing stream involved in the representation of communication sounds. Importantly, our results provide a neural counterpart for the human imaging and lesion findings and uncover a basis for a supposed role of the insula in processing vocal communication sounds such as speech.

“…Chun, 1997;Narumoto, Okada, Sadato, Fukui, & Yonekura, 2001;Rotshtein, Malach, Hadar, Graif, & Hendler, 2001, for related literature on humans). Both areas, STS and IT, have strong reciprocal connections to the amygdala, suggesting the amygdala receives highly processed facial information pertaining to both facial identity and facial expression (Baylis, Rolls, & Leonard, 1987;Fukuda et al, 1987;Nishijo, Ono, & Nishino, 1988b;Rolls, 1992). For example, Rotshtein et al (2001) found that lateral occipital cortex in humans, which processes facial expressions, is concerned with the configuration for each expression, rather than with its affective value.…”

Affect and cognition have long been treated as independent entities, but in the current review we suggest that affect and cognition are in fact highly interdependent. We open the article by discussing three classic views for the independence of affect. These are (i) the affective independence hypothesis, that emotion is processed independently from cognition, (ii) the affective primacy hypothesis, that evaluative processing precedes semantic processing, and (iii) the affective automaticity hypothesis, that affectively potent stimuli commandeer attention and evaluation is automatic. We argue that affect is not independent from cognition, that affect is not primary to cognition, nor is affect automatically elicited. The second half of the paper discusses several instances of how affect influences cognition. We review experiments showing affective involvement in perception, semantic activation, and attitude activation. We conclude that one function of affect is to regulate cognitive processing.
