DOI: 10.1002/brb3.886
Abstract: Categorization is a fundamental cognitive process, whereby the brain assigns meaning to sensory stimuli. Previous studies have found category representations in prefrontal cortex and posterior parietal cortex (PPC). However, these higher‐order areas lack the fine‐scale… read more here.

Neural correlates underlying the attentional spotlight in human parietal cortex independent of task difficulty

DOI: 10.1002/hbm.23709
Abstract: Changes in the size of the attentional focus and task difficulty often co‐vary. Nevertheless, the neural processes underlying the attentional spotlight process and task difficulty are likely to differ from each other. To differentiate between… read more here.

DOI: 10.1002/hbm.26089
Abstract: The human posterior cingulate, retrosplenial, and medial parietal cortex are involved in memory and navigation. The functional anatomy underlying these cognitive functions was investigated by measuring the effective connectivity of these Posterior Cingulate Division (PCD)… read more here.

DOI: 10.1007/s00429-021-02451-0
Abstract: Implicit motor learning and memory involve complex cortical and subcortical networks. The induction of plasticity in these network components via non-invasive brain stimulation, including transcranial direct current stimulation (tDCS), has shown to improve motor learning.… read more here.

tDCS over posterior parietal cortex increases cortical excitability but decreases learning: An ERPs and TMS-EEG study

DOI: 10.1016/j.brainres.2020.147227
Abstract: The application of anodal transcranial direct current stimulation (AtDCS) is generally associated with increased neuronal excitability and enhanced cognitive functioning. Nevertheless, previous work showed that applying this straight reasoning does not always lead to the… read more here.

TMS over posterior parietal cortex disrupts trans-saccadic visual stability

DOI: 10.1016/j.brs.2017.11.019
Abstract: BACKGROUND Saccadic eye movements change the retinal location of visual objects, but we do not experience the visual world as constantly moving, we perceive it as seamless and stable. This visual stability may be achieved… read more here.

DOI: 10.1016/j.celrep.2022.110504
Abstract: Rats readily switch between foraging and more complex navigational behaviors such as pursuit of other rats or prey. These tasks require vastly different tracking of multiple behaviorally significant variables including self-motion state. To explore whether… read more here.

DOI: 10.1016/j.cortex.2017.07.012
Abstract: With the advent of functional neuroimaging it quickly became apparent that successful episodic memory retrieval was consistently associated with enhanced activity in ventral lateral parietal cortex (VLPC), especially the left angular gyrus. Here, we selectively… read more here.
