Cortex (CORTEX)

Publisher: Elsevier

Journal description

Cortex is an international journal devoted to the study of the inter-relations of the nervous system and behavior, particularly as these are reflected in the effects of brain lesions on cognitive functions. It was founded in 1964. Tra le riviste italiane con maggior impact factor, raccoglie selezionati lavori di ricerca sulle attività nervose superiori. Si rivolge essenzialmente a un pubblico di neurologi e psicologi, ma tratta argomenti di pertinenza anche per gli psichiatri e per quanti sono interessati ad analizzare il comportamento umano e le sue alterazioni in termini di strutture e meccanismi anatomo-fisiologici. Dal 2001 il comitato scientifico, rinnovato e potenziato, è diretto dall'Editor in Chief dott. Sergio Della Sala. In occasioni del 40° anniversario sono stati rinnovati formato e grafica della rivista ed è stato accresciuto il sito web, che mette a disposizione l'archivio e, per gli abbonati, l'ultimo numero e gli articoli che saranno pubblicati nei prossimi numeri.

    ABSTRACT: In addition to exhibiting a severe contralesional deficit, hemianopic patients may also show a subtle ipsilesional visual deficit, called sightblindness (the reverse case of ‘blindsight). We have tested for the presence, nature and extent of such an ipsilesional visual field (IVF) deficit in hemianopic patients that we assigned to perform two visual tasks. Namely, we aimed to ascertain any links between this ipsilesional deficit, the lesion side, and the tasks performed or the stimuli used.

    ABSTRACT: Biases to favour self-related information over information related to other people have been demonstrated across a range of both high- and low-level tasks, but it is unclear whether these tasks ‘tap’ the same types of self representation. Here we assess results from two patients with damage primarily to (i) left ventro-medial prefrontal (vmPFC) cortex and the insula (patient SC), and (ii) temporo-parietal (TP) cortex (patient RR). We report evidence from both low-level perceptual matching tasks and episodic memory showing that SC has a hypoself bias across the tasks. RR in contrast had a hyperself bias confined to perceptual matching. Both patients also showed hypobias effects for reward. We argue that the different brain lesions compromise (i) the use of a core self-representation which modulates both perceptual and memorial levels of processing (the vmPFC), and (ii) attentional responses to social cues (the TP cortex), and, furthermore, these effects can dissociate from those of reward and general effects of brain lesion and/or impaired executive control. We suggest that the vmPFC is critical for access to a core self-representation while TP damage can reduce top-down control of attention to salient stimuli and exaggerates the effects of strong (self-related) attentional signals.

    ABSTRACT: A major theme driving research in congenital amusia is related to the modularity of this musical disorder, with two possible sources of the amusic pitch perception deficit. The first possibility is that the amusic deficit is due to a broad disorder of acoustic pitch processing that has the effect of disrupting downstream musical pitch processing, and the second is that amusia is specific to a musical pitch processing module. To interrogate these hypotheses, we performed a meta-analysis on two types of effect sizes contained within 42 studies in the amusia literature: the performance gap between amusics and controls on tasks of pitch discrimination, broadly defined, and the correlation between specifically acoustic pitch perception and musical pitch perception. To augment the correlation database, we also calculated this correlation using data from 106 participants tested by our own research group. We found strong evidence for the acoustic account of amusia. The magnitude of the performance gap was moderated by the size of pitch change, but not by whether the stimuli were composed of tones or speech. Furthermore, there was a significant correlation between an individual’s acoustic and musical pitch perception. However, individual cases show a double dissociation between acoustic and musical processing, which suggests that although most amusic cases are probably explainable by an acoustic deficit, there is heterogeneity within the disorder. Finally, we found that tonal language fluency does not influence the performance gap between amusics and controls, and that there was no evidence that amusics fare worse with pitch direction tasks than pitch discrimination tasks. These results constitute a quantitative review of the current literature of congenital amusia, and suggest several new directions for research, including the experimental induction of amusic behaviour through transcranial magnetic stimulation and the systematic exploration of the developmental trajectory of this disorder.

    ABSTRACT: Humans can readily decode emotion expressions from faces and perceive them in a categorical manner. The model by Haxby and colleagues proposes a number of different brain regions with each taking over specific roles in face processing. One key question is how these regions directly compare to one another in successfully discriminating between various emotional facial expressions.

    ABSTRACT: The neuropeptide oxytocin has been associated with promoting various social behaviors in humans including cooperation and trust. Surprisingly little, however, is known about the possible role of oxytocin in processes required for social interactive behavior such as joint task performance. The current study investigated whether intranasal administration of oxytocin leads to increased self-other integration using a social Simon task. A placebo-controlled double-blind between-subjects design was used. Behavioral and EEG measures were obtained from 63 healthy male volunteers who either received 24 IU oxytocin or a placebo while they performed the social Simon task in an individual and a joint/social context. The behavioral results demonstrated an enhanced Simon effect in the social context after oxytocin administration. At the electrophysiological level, the stimulus-locked N2 component, reflecting response conflict, was increased in the social compared to the individual context for Go trials, but only after oxytocin administration. The P3 component, reflecting response inhibition, was increased for social compared to individual contexts, irrespective of condition. Both the behavioral and N2 findings suggest that oxytocin enhances self-other integration. While more inhibition is needed in the social context, this process seems less sensitive to changes in self-other integration. To conclude, the current study is the first to show oxytocin-induced modulations of processes that play a central role in joint task performance and thus importantly adds to our understanding of the neurocognitive mechanisms underlying the diverse social effects of oxytocin.

    ABSTRACT: The observation of an action leads to the activation of the corresponding motor plan in the observer. This phenomenon of motor resonance has an important role in social interaction, promoting imitation, learning and action understanding. However, mirror responses not always have a positive impact on our behavior. An automatic tendency to imitate others can introduce interference in action execution and non-imitative or opposite responses have an advantage in some contexts. Previous studies suggest that mirror tendencies can be suppressed after extensive practice or in complementary joint action situations revealing that mirror responses are more flexible than previously thought. The aim of the present study was to gain insight into the mechanisms that allow response flexibility of motor mirroring. Here we show that the mere instruction of a counter-imitative mapping changes mirror responses as indexed by MEPs enhancement induced by TMS. Importantly, mirror activation was measured while participants were passively watching finger movements, without having the opportunity to execute the task. This result suggests that the implementation of task instructions activates stimulus-response association that can overwrite the mirror representations. Our outcome reveals one of the crucial mechanisms that might allow flexible adjustments of mirror responses in different contexts. The implications of this outcome are discussed.

    ABSTRACT: The title of this commentary tries to summarize its thesis, which could be more explicitly formulated as follows: the normative evolution of clinical research has profoundly modified and distorted the role of ethical committees (EC) so that they are perceived as an administrative barrier, rather than a support for innovative research. The neurosciences are possibly even more exposed to the risk of this ambiguity, while they should benefit the most from a positive collaboration with EC, if these maintain and develop their original role of promoters of research.

    ABSTRACT: Human voluntary actions are accompanied by a distinctive subjective experience termed "sense of agency". We performed three experiments using transcranial direct current stimulation (tDCS) to modulate brain circuits involved in control of action, while measuring stimulation-induced changes in one implicit measure of sense of agency, namely the perceived temporal relationship between a voluntary action and tone triggered by the action. Participants perceived such tones as shifted towards the action that caused them, relative to baseline conditions with tones but no actions. Actions that caused tones were perceived as shifted towards the tone, relative to baseline actions without tones. This 'intentional binding' was diminished by anodal stimulation of the left parietal cortex [targeting the angular gyrus (AG)], and, to a lesser extent, by stimulation targeting the left dorsolateral prefrontal cortex (DLPFC), (Experiment 1). Cathodal AG stimulation had no effect (Experiment 2). Experiment 3 replicated the effect of left anodal AG stimulation for actions made with either the left or the right hand, and showed no effect of right anodal AG stimulation. The angular gyrus has been identified as a key area for explicit agency judgements in previous neuroimaging and lesion studies. Our study provides new causal evidence that the left angular gyrus plays a key role in the perceptual experience of agency. Copyright © 2015 Elsevier Ltd. All rights reserved.
