Here, we assessed whether genetic variations of [[CHRNA7]] affect coherent motion perception. Motion perception has been shown to decline with age, and it has previously been suggested that the effects of genetic variations are magnified by age. Therefore, we tested both older (n = 62) and younger adults (n = 63). We found that motion coherence thresholds were significantly higher for older compared to younger adults, which is in accordance with previous studies. Interestingly, there was a strong relationship between variants of the SNP rs2337980 of the [[CHRNA7]] and motion direction discrimination. In particular, participants carrying the TC genotype had considerably lower motion coherence thresholds than CC carriers. The effect of genotype did not interact with age. Our results show that genetic variations are associated with perceptual performance, but are unlikely to explain age-related changes.<br /> |mesh-terms=* Adult<br /> * Differential Threshold<br /> * Female<br /> * Genotype<br /> * Humans<br /> * Male<br /> * Motion Perception<br /> * Polymorphism, Single Nucleotide<br /> * Receptors, Nicotinic<br /> * Sensory Thresholds<br /> * Young Adult<br /> * alpha7 Nicotinic Acetylcholine Receptor<br /> |keywords=* Aging<br /> * CHRNA7<br /> * Cholinergic system<br /> * Coherent motion<br /> * Genetic variations<br /> |full-text-url=https://sci-hub.do/10.1007/s00221-019-05627-7<br /> }}</div>
