Easy to process, hard to control: Transient and sustained processing fluency im...
Oliveira, Gonçalo A; Remondes, Miguel; Garcia-Marques, TeresaRecent research suggests that the cognitive monitoring system of control could be using negative affective cues intrinsic to changes in information processing to initiate top-down regulatory mechanisms. Here, we propose that positive feelings of ease-of-processing could be picked up by the monitoring system as a cue indicating that control is not necessary, leading to maladaptive control adjustments. We simulta...
Functional characterization of neural circuits responsible for goal-directed be...
Remondes, MiguelThe ability of selecting actions based on desired goals, according to knowledge stored previously in memory, is essential for survival. However, we must also be ready to adapt such behaviour to unexpected changes in context, often contrary to what would be supported by previous knowledge. Consistently, medical literature, fMRI, and electrophysiology studies, suggest a dialogue between the medial temporal struct...
Bad after bad is good: previous trial disfluency reduces interference promoted ...
Oliveira, Gonçalo Aires De; Remondes, Miguel; Garcia-Marques, TeresaConflict and perceptual disfluency have been shown to lead to adaptive, sequential, control adjustments. Here, we propose that these effects can be additive, suggesting their integration into a general feeling of disfluent information processing. This hypothesis was tested using an interference task that dynamically mixed trials varying in legibility and/or congruence. Moreover, the manipulation of the proporti...
Transection of the superior sagittal sinus enables bilateral access to the rode...
Dias, Marcelo; Marques-Morgado, Inês; Coelho, Joana E; Ruivo, Pedro; Lopes, Luisa V.; Remondes, MiguelStereotaxic access to brain areas underneath the superior sagittal sinus (SSS) is notoriously challenging. As a major drainage vessel, covering the whole extension of the sagittal fissure, the SSS impedes direct bilateral access to underlying regions for recording and stimulation probes, drug-delivery cannulas, and injection devices. We now describe a new method for transection and retraction of the SSS in rats...
