Perlia's nucleus, also known as nucleus of Perlia and abbreviated as NP, is a spindle-shaped nucleus located in the mesencephalon, a subdivision of the Edinger-Westphal nucleus [1] [2] situated between the right and left oculomotor nuclei. It is implicated in parasympathetic oculomotor functions, possibly including input to the iris and ciliary.
The Edinger–Westphal nucleus refers to the adjacent population of non-preganglionic neurons that do not project to the ciliary ganglion, but rather project to the spinal cord, dorsal raphe nucleus, lateral septal nuclei, lateral hypothalamic area and the central nucleus of the amygdala, among other regions.
The zona incerta receives pain input through the spinothalamic tract and this has been shown to control the activity of the pain transmission pathway in the posterior thalamus. [15] Electrical or chemical stimulation of the zona incerta creates limbic-related movements, such as those associated with defense orientation and copulation. [28]

The subparabrachial nucleus (also known as the Kölliker-Fuse nucleus, or diffuse reticular nucleus) regulates the breathing rate. It receives signals from the caudal , cardio-respiratory part of the solitary nucleus and sends signals to the lower medulla oblongata , the spinal cord , the amygdala and the lateral hypothalamus .
In neuroanatomy, the pretectal area, or pretectum, is a midbrain structure composed of seven nuclei and comprises part of the subcortical visual system.Through reciprocal bilateral projections from the retina, it is involved primarily in mediating behavioral responses to acute changes in ambient light such as the pupillary light reflex, the optokinetic reflex, and temporary changes to the ...
The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: . paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus
The medial lemniscus carries axons from most of the body and terminates by synapsing with third-order neurons in the ventral posterolateral nucleus of the thalamus. [3] at the level of the mamillary bodies. Sensory axons transmitting information from the head and neck via the trigeminal nerve synapse at the ventral posteromedial nucleus of the ...
