Resumen:
Functional hemodynamic response was studied in a new Verbal Fluency Task (VFT) that demanded the
production of geographical words while fMRI data was obtained. Participants completed 7 trials with a total duration
of 2 min. 20 s. Four simple arithmetic subtraction trials were alternated with 3 geographical naming trials. Each trial had
a duration of 20 s. Brain activity was contrasted between both conditions and significant differences (p < .05, Family Wise
Error correction) were observed in the prefrontal medial gyrus, typically associated with word retrieval and phonological
awareness, and in the parahippocampal gyrus, posterior cingulate cortex and lingual gyrus, areas related to spatial
cognition. These results indicate that geographic VFT could be incorporated into a browser of cognitive processes using
VFT considering its specific relationship with spatial cognition. Further investigations are proposed, taking special
interest in the gender variable and eliminating phonological restrictions, because the evoked Argentinean cities and
towns ended in a consonant letter.
