pretectal nucleus meaning in Hindi

Examples

1. Most of these fibers synapse in the lateral geniculate nucleus or the pretectal nucleus.
2. These neuronal electrical signals travel through neuronal axons to specific brain targets, such as the center of pupillary control called the olivary pretectal nucleus ( OPN ) of the midbrain.
3. These brain regions include the SCN, where input from ipRGCs is necessary to photoentrain circadian rhythms, and the olivary pretectal nucleus ( OPN ), where input from ipRGCs control the pupillary light reflex.
4. Most of the axons of the optic nerve terminate in the lateral geniculate nucleus from where information is relayed to the visual cortex, while other axons terminate in the pretectal nucleus and are involved in reflexive eye movements.
5. The five primary nuclei are : the olivary pretectal nucleus ( ON ), the nucleus of the optic tract ( NOT ), and the anterior ( NPA ), medial ( NPM ), and posterior ( NPP ) pretectal nuclei.
6. These targets include the olivary pretectal nucleus ( a center responsible for controlling the pupil of the eye ), the LGN, and, through the retinohypothalamic tract ( RHT ), the suprachiasmatic nucleus of the hypothalamus ( the master pacemaker of circadian rhythms ).
