Among the RFamide peptide family, LPXRFamide (LPXRFa) group regulates release of various pituitary hormones and, recently, LPXRFa genes were found to be regulated by photoperiod via melatonin. As a first step towards investigating role on reproductive function in grass puffer (Takifugu niphobles), which spawns semilunar cycles, encoding and its receptor (LPXRFa-R) cloned, seasonal, diurnal circadian changes their absolute amounts mRNAs brain examined quantitative real-time polymerase chain...

We can easily recognize human movements from very limited visual information (biological motion perception). The present study investigated how upper and lower body areas contribute to direction discrimination of a point-light (PL) walker. Observers judged the that PL walker was facing. performed either normal walking or hakobi, style used in traditional Japanese performing arts, which amount local extremities is much smaller than walking. Either upper, lower, full presented. Discrimination...

In seasonally breeding animals, the circadian and photoperiodic regulation of neuroendocrine system is important for precisely‐timed reproduction. Kisspeptin, encoded by K iss1 gene, acts as a principal positive regulator reproductive axis stimulating gonadotrophin‐releasing hormone ( G n RH ) neurone activity in vertebrates. However, precise mechanisms underlying cyclic kisspeptin remain largely unknown. The grass puffer, T akifugu niphobles , exhibits unique spawning rhythm: occurs 1.5–2 h...

Gaze direction can be represented in terms not only of local-feature information (ie the location pupil eye socket), but also an emergent property—whether perceived gaze is straight or averted. To examine whether this property preferentially accessed when searching for oddly directed gaze, we experimentally manipulated and independently, order to investigate influences both types on visual searches gaze. We found that primary determinant search efficiency was region, property—the This...

Abstract Early intervention is now considered the core treatment strategy for autism spectrum disorders (ASD). Thus, it of significant clinical importance to establish a screening tool early detection ASD in infants. To achieve this goal, longitudinal design, we analyzed spontaneous bodily movements 4-month-old infants from general population and assessed their ASD-like behaviors at 18 months age. A total 26 movement features were calculated video-recorded 4 Their risk was age with Modified...
