| For example, it is possible that the brainstem reticular formation is divided into the same number of nuclei in all jawed vertebrates. |
|
| Microinjections of muscimol and bicuculline into the pontine reticular formation modify the sleep-waking cycle in the rat. |
|
| Some fibers of the hypoglossal nerve can be traced through the reticular formation as they course towards the ventrolateral sulcus. |
|
| The reticular formation consists of a vast number of small interconnected neurons occupying the central area of the brainstem. |
|
| The brainstem reticular formation should not, however, be called the seat of consciousness. |
|
| The midbrain also contains a portion of the reticular formation, a neural network that is involved in arousal and alertness. |
|
| Neurons of the reticular formation play a central role in the transmission of motor and sensory impulses. |
|
| The parasympathetic preganglionic neurons that regulate these functions originate in the reticular formation of the medulla oblongata. |
|
| Suggestions for regions of the brain that could be the site of action have included the brain stem reticular formation, the cerebral cortex, and the thalamus. |
|
| The hypothalamus has important links to pleasure and misery, while the reticular formation may have an important link to depression. |
|
| The spongy degeneration in the brain stem and spinal cord, especially in the reticular formation, has been found to relate closely to learning and memory deficits. |
|
| The mechanisms of arousal involve both direct and indirect connections of receptors with the central nervous system and parts of the reticular formation. |
|
| The medulla likewise houses a portion of the reticular formation. |
|
| The other main pathway of pain impulses ends in the reticular formation of the medulla oblongata and pons and is known as the spinoreticular tract. |
