The Right Frontopolar Cortex Is Involved in Visual-Spatial Prospective Memory
2013
The involvement of frontopolar cortex in mediating prospective memory processes has been evidenced by various studies, mainly by means of neuroimaging techniques. Recently, one transcranial magnetic stimulation study documented that transient inhibition of left Brodmann Area (BA) 10 impaired verbal prospective memory. This result raises the issue of whether the BA 10 involvement in prospective memory functioning may be modulated by the physical characteristics of the stimuli used. The present study aimed to investigate the role of the frontopolar cortex in visual-spatial PM by means of the application of inhibitory theta-burst stimulation. Twelve volunteers were evaluated after inhibitory t…
Response to Skeide and Friederici: The myth of the uniquely human “direct” dorsal pathway
2015
In their comment on our recent article [1], Skeide and Friederici [2] claim ‘that some important data not discussed by Bornkessel-Schlesewsky et al. strongly support the view that there are clear qualitative, and not merely quantitative, differences between [human and nonhuman primate] species with respect to both the intrinsic functional connectivity of frontal and temporal cortices, and their direct structural connection via a dorsal white matter fiber tract.’ This obviously refers to work by Friederici and colleagues [3] emphasizing the functional importance of a direct connection between the posterior superior temporal cortex (pSTC) and Brodmann area (BA) 44 in humans, and its absence i…
Sensory system interactions during simultaneous vestibular and visual stimulation in PET
2002
The patterns of regional cerebral blood flow (rCBF) increases and decreases in PET were compared for unimodal vestibular, unimodal visual, and for simultaneous vestibular and visual stimulation. Thirteen healthy volunteers were exposed to a) caloric vestibular stimulation, b) small-field visual motion stimulation in roll, c) simultaneous caloric vestibular and visual pattern stimulation. Unimodal vestibular stimulation led to activations of vestibular cortex areas, in particular the parieto-insular vestibular cortex (PIVC), and concurrent deactivations of visual cortical areas [Brodmann area (BA) 17-19]. Unimodal visual motion stimulation led to activations of the striate visual cortex and …
