Example sentences for: photoreception

How can you use “photoreception” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • About six years ago, explains Zuker, who previously worked on other sensory systems in flies, ‘there was a disconnect between our understanding of sensations in the case of photoreception, mechanoreception, touch, and so on and what we knew about taste’.

  • We assume that the effects on sleep we observed in cry1 , 2 -/-mice are a result of a lack of cryptochrome -dependent inhibition of the transcriptional activation provided by the bHLH-PAS heterodimers CLOCK:BMAL1 and NPAS2:BMAL1 [ 19 20 37 ] , although cryptochromes also play a role in stabilizing and nuclear sequestration of PER proteins [ 38 ] , and in photoreception [ 39 ] . Lack of cryptochromes results in increased mRNA levels of CLOCK/NPAS2:BMAL1 target genes, including the circadian genes per1 and per2 [ 20 23 ] . The expression of these two genes is viewed as a state variable of the molecular circadian clock or a marker of CLOCK/NPAS2:BMAL1-induced transcription, although at least per1 transcription can also be (rapidly) induced by light [ 40 41 ] , through a CREB-dependent signaling pathway [ 42 43 44 ] . The observation of high brain levels of per1,2 transcripts under baseline conditions in cry1,2 -/-mice raises the possibility that these or other CLOCK/NPAS2:BMAL1 target genes are involved in the homeostatic regulation of sleep.

  • The optic lobe primordium and brain of late third instar larvae have only limited functions in larval photoreception and contain only a small number of mature neurons.
