Diencephalic projections from the midbrain reticular formation
Abstract:
(1) Physiologically guided stereotaxic coagulation was placed so as to avoid major through pathways in the midbrain reticular formation of 7 cats. Diencephalic degeneration resulting from this was traced by the Nauta method. (2) Preterminal degeneration was found in: the intralaminar nuclei and the posterior group (PO); the ventral group of thalamic nuclei; the ventral thalamus, including the zona incerta, subthalamus and fields of Forel; and the lateral hypothalamus. (3) The results are discussed in relation to somatomotor reactions, reticular influences on the electroencephalogram and telencephalic representation of pain.

Olivary Nucleus
The olivary nucleus, or inferior olivary nucleus, is located within the ventrolateral part of the medulla oblongata. It is primarily involved in motor coordination and motor learning. The olivary nucleus receives input from the spinal cord, cerebellum, and motor...
Functional Brain Systems: Reticular Formation
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...
