EEG signals were recorded from frontal cortex, hippocampus, striatum and reticular formation
from inside a totally copper shielded room.
However, Siegel et al (24), on the basis of unit activity recorded from the brainstem reticular formation
reported the presence of certain characteristic features associated with REM sleep state in echidna.
Distractibility, an executive function deficit, appears to involve dopaminergic and noradrenergic systems in the reticular formation
, prefrontal cortex, and corpus callosum, and is best treated with methylphenidate or dextroamphetamine, he said.
They do, however, exert an influence over spinal interneurons through the rubrospinal and reticulospinal pathways via the brain stem by means of the red nuclei and reticular formation
Subsequent investigations into the neural pathways of orexinergic neurons found that they project into brainstem areas such as the locus ceruleus, raphe nuclei, and reticular formation
that control various aspects of rapid eye movement (REM) sleep and wake.
2) Along the course between the cochlear nuclei and the olivary complex, auditory fibers functionally interact with reticular formation
structures and form the nonspecific acoustic pathway.
Vestibular and optokinetic inputs come from the vestibular nuclei, saccadic commands arise from burst neurons in the paramedian pontine reticular formation
(PPRF), pursuit signals from the cerebellum are relayed in vestibular nuclei and the signal required to hold the eye steady in its new position (gaze-holding mechanism) reaches the abducens nuclei from the nucleus prepositus hypoglossi.
An area where the quick component of nystagmus is generated is in the reticular formation
En route to the brain, projections of this tract stimulate the reticular formation
, periaqueductal gray, hypothalamus and both the medial and intralaminar thalamic nuclei, before connecting with the limbic system and higher centers of the brain.
