摘要视觉偏侧化是许多脊椎动物的典型特征，但其潜在的神经动力学机制尚不清楚。本研究通过行为学和电生理实验，研究了峨眉音乐蛙的捕食反应和动态脑活动，以评估其潜在的眼球偏好及其潜在的动态神经机制。为此，当猎物刺激(以活蟋蟀和树叶为对照)在青蛙周围以等速顺时针和逆时针方向移动时，计数端脑、间脑和中脑的捕食反应次数并测量每个频段的脑电(EEG)绝对功率谱。结果表明：(1)对照(LEAT)的捕食反应数无显著差异，但顺时针移入左侧视野(LVF)时，右侧视野(RVF)的捕食反应数显著多于左侧视野(LVF)：(2)当猎物刺激顺时针移入右侧视野(RVF)时，各脑电频段的功率谱均大于无刺激的视野和左侧视野(LVF)；(3)在顺时针方向上，左侧间脑的β、α、β频段功率谱显著大于右侧间脑，而在逆时针方向上，Delta波、α频段和α频段的功率谱也有显著差异。总而言之，这些结果表明，音乐蛙存在右眼对掠夺行为的偏好，脑电振荡的动力学可能是这种右眼/左脑优势的基础。摘要：乐蛙(Nidirana DaunChina)的捕食反应表明，脑电高频振荡可能在右眼偏好中发挥重要作用。
ABSTRACT Visual lateralization is a typical characteristic of many vertebrates; however, its underlying dynamic neural mechanism is unclear. In this study, predatory responses and dynamic brain activities were evaluated in the Emei music frog (Nidirana daunchina) to assess the potential eye preferences and their underlying dynamic neural mechanism, using behavioral and electrophysiological experiments, respectively. To do this, when the prey stimulus (live cricket and leaf as control) was moved around the frogs in both clockwise and anticlockwise directions at constant velocity, the number of predatory responses were counted and electroencephalogram (EEG) absolute power spectra for each band were measured for the telencephalon, diencephalon and mesencephalon. The results showed that: (1) no significant differences in the number of predatory responses could be found for the control (leaf), but the number of predatory responses for the right visual field (RVF) was significantly greater than that for the left visual field (LVF) when the live cricket was moved into the RVF clockwise; (2) compared with no stimulus in the visual field and stimulus in the LVF, the power spectra of each EEG band were greater when the prey stimulus was moved into the RVF clockwise; and (3) the power spectra of the theta, alpha and beta bands in the left diencephalon were significantly greater than those of the right counterpart for the clockwise direction, but similar significant differences presented for the delta, theta and alpha bands in the anticlockwise direction. Together, the results suggested that right-eye preferences for predatory behaviors exist in music frogs, and that the dynamics of EEG oscillations might underlie this right eye/left hemisphere advantage. Summary: Predatory responses in the music frog (Nidirana daunchina) indicate that EEG oscillations at higher frequency may play important roles in right-eye preference.
