Patient assessment based on a theory of visual attention (TVA): subtle deficits after a right frontal-subcortical lesion.

We report on a patient who complained of reduced awareness in the left visual field, but showed no visual neglect or extinction in clinical testing. By MR scanning, the brain damage was localized to the right basal ganglia, also involving structures in ...

Effect of parietal lobe lesions on saccade targeting and spatial memory in a naturalistic visual search task.

The eye movements of two patients with parietal lobe lesions and four normal observers were measured while they performed a visual search task with naturalistic objects. Patients were slower to perform the task than the normal observers, and the patients ...

Function of hippocampus in "insight" of problem solving.

Since the work of Wolfgang Kohler, the process of "insight" in problem solving has been the subject of considerable investigation. Yet, the neural correlates of "insight" remain unknown. Theoretically, "insight" means the reorientation of ones thinking, ...

Does the cerebellum contribute to specific aspects of attention?

We present data on attentional and neuropsychological functions of 16 patients with focal cerebellar lesions (13 tumours, 3 haematomas) compared to normative test data, and to 11 control subjects matched for age, gender, and years of education. Patients ...

The lasting impression of chairman Mao: hyperfidelity of familiar-face memory.

We examined the accuracy of a highly-familiar-face representation in memory. In experiment 1, a famous portrait of Chairman Mao was digitally altered in terms of the distance between his two eyes, two pixels at a time. Mainland Chinese adults were shown ...

Linguistic theory and neuroimaging evidence: an fMRI study of Brocas area in lexical semantics.

There has been a long debate on the functional characterization of left inferior frontal cortex, including proposals regarding syntactic and lexico-semantic involvement. We studied nine right-handed adults, using functional magnetic resonance imaging ...

Perceptual illusion and the real-time control of action.

Participants were cued by an auditory tone to grasp a target object from within a size-contrast display. The peak grip aperture was unaffected by the perceptual size illusion when the target array was visible between the response cue and movement onset ...

Reasoning and working memory: common and distinct neuronal processes.

The neuronal processes underlying reasoning and the related working memory subsystems were examined with functional magnetic resonance imaging (fMRI). Twelve volunteers solved relational reasoning problems which either supported a single (determinate) or ...

Code-switching across brainstorming sessions: implications for the revised hierarchical model of bilingual language processing.

The revised hierarchical model (RHM) of bilingual language processing posits independent word form representations for the dominant language (L1) and the nondominant language (L2), facilitated translation from L2 words to L1 words, access to common ...

Feature binding in object-file representations of multiple moving items.

Maintenance of episodic representations by feature-location binding is important for visual cognition. It has been proposed that we can hold and update coherent episodic representations of up to four objects. This study investigated the dynamic ...
