概括

金鱼可以通过视觉训练来调整它们的垂直和扭曲光动力学反应 (OKR),即使它们最初在这些方向上表现出最小的反应. 这种适应突显了它们视觉运动系统的可塑性.

科学领域:

神经科学是一个神经科学.
比较生理学比较生理学
视觉科学视觉科学视觉科学

背景情况:

脊椎动物的眼睛运动通过前庭眼反射 (VOR) 和光运动反应 (OKR) 来稳定视力.
当VOR的有效性下降时,OKR可以弥补长时间的头部运动.
鱼类中OKR的3D性质和适应性在很大程度上仍未被探索.

研究的目的:

研究金鱼的三维 (3D) 光动力学反应 (OKR),包括水平 (H),垂直 (V) 和扭曲 (T) 组件.
通过视觉训练来评估V和TOKR的适应能力和记忆保留.
为了将OKR与金鱼和鱼的自然头部运动模式相关联.

主要方法:

在原始金鱼中评估了水平,垂直和扭矩OKR.
利用视觉训练范式来诱导V和TOKR的适应.
适应OKR的测量记忆保留.
分析了自由游泳的金鱼和鱼的头部运动.

主要成果:

纯粹的金鱼表现出强大的HOKR,但V和TOKR最小.
视觉训练增加了V和TOKR的收益,使用更平的频谱.
与HOKR和VOKR相比,适应的TOKR显示记忆衰退速度较慢.
头部运动分析揭示了与运动相关的轴特定模式.

结论:

金鱼具有可适应的V和TOKR,这对视觉运动功能至关重要.
OKR的适应性反映了特定物种的运动行为和感官体验.
原始金鱼的最小V和TOKR是固有的特性,而不是肌肉限制.
不对称的TOKR适应性可能与食行为有关.

Osmoregulation in Fishes

Osmoregulation in Fishes

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

The Vestibular System

The Vestibular System

The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Equilibrium and Balance

Equilibrium and Balance

The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
