Reward processing is a fundamental human activity. The basal ganglia are recognized for their role in reward processes; however, specific roles of the different nuclei (e.g., nucleus accumbens, caudate, putamen and globus pallidus) remain unclear. Using quantitative meta-analyses we assessed whole-brain and basal ganglia specific contributions to money, erotic, and food reward processing. We analyzed ...

The sensorimotor cortex is somatotopically organized to represent the vocal tract articulators, such as lips, tongue, larynx, and jaw. How speech and articulatory features are encoded at the subcortical level, however, remains largely unknown. We analyzed local field potential (LFP) recordings from the subthalamic nucleus (STN) and simultaneous electrocorticography recordings from the sensorimotor cortex of ...

Patient studies and brain stimulation evidence suggest that language processing can be enhanced by altering the interhemispheric balance: namely, preferentially enhancing left-hemisphere activity while suppressing right-hemisphere activity. To our knowledge, no study has yet compared the effects of such bilateral brain stimulation to both logically necessary control conditions (separate left- and right-hemisphere stimulation). This study did so ...

Previous clinical research has shown a positive effect of instrumentality on verb retrieval in individuals with aphasia. Performance on instrumental verbs incorporating an obligatory tool into their conceptual representation (e.g., to cut) is more accurate compared to non-instrumental verbs (e.g., to tear), possibly due to more specific conceptual representations of instrumental verbs. Seeking the neural correlates of ...

Brain responses of 7–10-year-old Finnish children to two speech contrasts incorporated in pseudowords (PWs) and varying in perceptual difficulty were studied. An oddball paradigm was used to record event-related potentials (ERPs) to a standard PW /baka/ and two deviant PWs: the easier = /baga/ and the more difficult /bag*a/ that sounded as intermediate between /baka/ ...

Effects of representational distance between meanings on the neural correlates of semantic ambiguity
Grindrod C. M., Garnett E., Malyutina S. et al., Brain and Language 2014 Vol. 139 P. 23–35
Psycholinguistic research demonstrates that representational distance between meanings influences recognition of ambiguous words. Our goal was to investigate whether the neural correlates of ambiguity are also modulated by representational distance as a function of syntactic similarity (i.e., grammatical class) and meaning dominance. In an event-related fMRI experiment, participants completed a visual lexical decision task that ...

The basal ganglia have traditionally been viewed as motor processing nuclei; however, functional neuroimaging evidence has implicated these structures in more complex cognitive and affective processes that are fundamental for a range of human activities. Using quantitative meta-analysis methods we assessed the functional subdivisions of basal ganglia nuclei in relation to motor (body and eye ...

The use of eventrelated fMRI makes it possible to investigate spatiotemporal dynamics of cortical and subcortical human brain structures activity during voluntary movement performance in response to pre sentation of relevant verbal stimuli. The results ofthe study showed that voluntary movement was asso ciated with higher contralateral brain activation ina number of areas: primary motor ...

Neuronal activity in the subthalamic nucleus (STN) of patients with Parkinson's disease (PD) is characterised by excessive neuronal synchronization, particularly in the beta frequency range. However, less is known about the temporal dynamics of neuronal oscillations in PD. In this respect long-range temporal correlations (LRTC) are of special interest as they quantify the neuronal dynamics ...

In Parkinson's disease (PD) levodopa-associated changes in the power and long-range temporal correlations of beta oscillations have been demonstrated, yet the presence and modulation of genuine connectivity in local field potentials (LFP) recorded from the subthalamic nucleus (STN) remains an open question. The present study investigated LFP recorded bilaterally from the STN at wakeful rest ...

The purpose of the present study was to identify general and syndrome-specific deficits in the lexical processing of individuals with non-fluent and fluent aphasia compared to individuals without cognitive, neurological or language impairments. The time course of lexical access, as well as lexical selection and integration was studied using a visual-world paradigm in three groups ...
