optic chiasma
(noun)
found at the base of the brain and coordinates information from both eyes
Examples of optic chiasma in the following topics:
-
Visual Processing
- The myelinated axons of ganglion cells make up the optic nerves.
- This crossing of optical pathways produces the distinctive optic chiasma (Greek, for "crossing") found at the base of the brain and allows us to coordinate information from both eyes.
-
Organic Enantiomers
- The two main types of stereoisomerism are diastereomerism (including 'cis-trans isomerism') and optical isomerism (also known as 'enantiomerism' and 'chirality').
- Enantiomers are two optical isomers (i.e. isomers that are reflections of each other).
- Compounds that are enantiomers of each other have the same physical properties except for the direction in which they rotate polarized light and how they interact with different optical isomers of other compounds.
-
Reception
- This scheme shows the flow of information from the eyes to the central connections of the optic nerves and optic tracts, to the visual cortex.
-
The Vestibular System
- Finally, the vestibular signals project to certain optic muscles to coordinate eye and head movements.
-
Transduction of Light
- The now-active bipolar cells in turn stimulate the ganglion cells, which send action potentials along their axons (which leave the eye as the optic nerve).
-
Microscopy
- The optics of a microscope's lenses change the orientation of the image that the user sees.
-
Characteristics of Mammals
- The optic lobes, located in the midbrain, are divided into two parts in mammals, whereas other vertebrates possess a single, undivided lobe.
-
Establishing Body Axes during Development
- The prosencephalon further goes on to develop into the telencephalon (the forebrain or cerebrum) and the diencephalon (the optic vesicles and hypothalamus).
