在灵长类动物中,认知要求高的任务会引起微妙的眼动,作为行为指标. 这些眼睛运动与上层眼球 (SC) 和抽象视觉分类有关.
科学领域:
- 神经科学是一个神经科学.
- 认知科学 认知科学
- 灵长类动物的行为
背景情况:
- 人类和动物学习复杂的任务,认知变量编码在眼运动大脑区域.
- 之前的研究表明,在苛刻的任务中,认知变量在核心眼运动区域有强烈的编码.
研究的目的:

Vision
52.4K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Association Areas of the Cortex
4.6K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Accessory Structures of the Eye
1.3K
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...
