The blood oxygenation level dependent (BOLD) response during sustained visual stimulation has been studied by several groups using fMRI with controversial conclusions. This issue was investigated for the human brain at high (4 Tesla) magnetic field strength using a flashing goggle at 8 Hz. The resul
The nature of the signal undershoot observed in the inter-stimulation intervals in fMRI studies using a block paradigm consisting of alternating periods of visual stimulation and rest was investigated using the following single shot EPI sequences: gradient echo (GRE), spin echo (SE), spin echo with
The effects of intravenous doses (200 mug) of LSD on the activity of single neurones in the primary visual cortex have been studied in cats anaesthetized with urethane. Cells were stimulated with a bright bar of light moved over the receptive field, and orientation tuning was assessed quantitatively
