In terms of output or efferents, both superior colliculi have axonal projections into various subcortical structures, such as the, reticular formation, spinal cord, lateral geniculate nucleus, and pulvinar of the thalamus. The pulvinar is regarded as a center of image interpretation that helps the ...
Intermediate and deep neurons also send motor projections directly to the eyes. Visual signals from the right side of the retinas cross into the left hemisphere of the. There is a similar crossover with the superior colliculus' control of eye movement. Cells in the left tectum will orient eye...
There is very elegant work on how specific cell populations in the hypothalamus process aggression [10], or how specific circuits in the superior colliculus and periaqueductal gray process fear [11]. We know a lot about the stimuli (the smell of another animal, or an overhead looming shadow...
What is the main function of the superior colliculus, and why is it thought to be a site of multisensory integration?Sensory Systems:Sensory systems are the organs that help us to sense the environment around us. They allow for a wide range o...
in almost all mammalian species, most optic fibers reach the accessory optic nuclei via the transpeduncular tract, which is visible as it courses over the brachium of the superior colliculus.figure 1. neuroanatomical connections of the accessory optic system. the brainstem is depicted from the ...
The superior olivary complex, inferior colliculus, and cochlear nucleus make up the auditory pathway. Its main function is carrying messages from the cochlea. It is part of the larger auditory system tasked with providing meaning and access to communication tools. ...
In addition, the superior colliculus form the tectospinal tract, which is important in the reflex movements of the head and eyes, such as closure of the eyelids before a foreign body can reach the eye. Finally, the reticular formation forms the reticulospinal tract, which is essential in ...
There was not a widespread effect of the higher DHA supple- mentation on tissue ARA content as it was lowered only in the plasma (by 22%), globus pallidus (by 11%) and superior colliculus (by 5%) relative to the animals fed the 0.42 wt% DHA formula. There is a well known antagonism...
Cerebrospinal fluid is a clear, colorless fluid that surrounds and protects the brain and spinal cord in the central nervous system. It is produced by two small glands known as the choroid plexuses. The cerebrospinal fluid is composed of about 95% water, 3% protein, 1% glucose, and ...
