Portuguese Abstract: The ability to learn about the signs of variability in space and time is known as time place learning(TPL). To adjust their circadian rhythms, animals use stimuli that change regularly, such as the light-darkcycle, temperature, food availability or even social stimuli. Because light-dark cycle is the most importantenvironmental temporal cue, we asked how a diurnal animal would perform TPL if this cue was removed.Zebrafish has been extensively studied in the chronobiology area due to it diurnal chronotype, thus, westudied the effects of constant light and constant dark on the time-place learning and activity profile inzebrafish. Our data show that while under constant light and dark condition zebrafish was not able of TPL,after 30 days under the constant conditions, constant light led to higher activity level and less significant(robust) 24 h rhythm
