Accessory Structures of the Eye01:17

Accessory Structures of the Eye

4.2K
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...

Vision01:24

Vision

48.4K
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.

Muscles of the Eye01:20

Muscles of the Eye

6.2K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Focusing of Light in the Eye01:16

Focusing of Light in the Eye

5.9K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

2.6K
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Anatomy of the Eyeball01:20

Anatomy of the Eyeball

8.3K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Summary
This summary is machine-generated.

Spontaneous fetal eye movements in utero are linked to brain activity in visual and frontal areas. This suggests the human visuomotor system prepares for visual input before birth.

Area of Science:

  • Neuroscience
  • Developmental Neuroscience
  • Cognitive Neuroscience

Background:

  • The visuomotor system develops rapidly postnatally.
  • Spontaneous activity in visual cortical areas is observed in vertebrates before birth.
  • Previous studies could not link in utero eye movements with functional brain activity using fetal fMRI.

Purpose of the Study:

  • To investigate the link between in utero fetal eye movements and functional brain networks.
  • To explore the early development of the human visuomotor system before birth.

Main Methods:

  • Acquired BOLD resting-state fMRI data from seven fetuses (30-36 weeks gestation).
  • Detected and tracked fetal eye movements during MRI scans.
  • Analyzed functional brain activity correlated with eye movements.

Main Results:

  • Spontaneous fetal eye movements in utero were found to be linked with simultaneous activity in visual and frontal cerebral areas.
  • Evidence suggests a connection between visual and motor areas during fetal development.

Conclusions:

  • Spontaneous fetal eye movements are associated with functional brain networks in utero.
  • This study provides evidence for the preparation of the human visuomotor system prior to birth.
