Late effect of dopamine D1/5 receptor activation on stimulus-induced BOLD responses in the hippocampus and its target regions depends on the history of previous stimulations

Autor: Frank Angenstein, Wolfgang Tischmeyer, Cornelia Helbing

Publikováno v: NeuroImage 152, 119-129 (2017). doi:10.1016/j.neuroimage.2017.02.077

fMRI was used to study late effects of dopamine D 1/5 receptor activation on hippocampal signal processing and signal propagation to several target regions. The dopamine D 1/5 receptor agonists SKF83959 and SKF38393 were intraperitoneally applied wit

The role of ongoing neuronal activity for baseline and stimulus-induced BOLD signals in the rat hippocampus

Autor: Frank Angenstein

Publikováno v: NeuroImage 202, 116082 (2019). doi:10.1016/j.neuroimage.2019.116082

To understand how ongoing neuronal activity affects baseline BOLD signals, neuronal and resultant fMRI responses were simultaneously recorded in the right hippocampus of male rats during continuous low-frequency (2 or 4 Hz) pulse stimulation of the r
