Looking at a major visual relay station, he found that the parvocellular systems were similar in all brains. The particular pathway used for color discrimination is the parvocellular pathway. The second pathway, the parvocellular system, is composed of smaller cells that carry out slower processes. It also contains descending axonal fibers from the parvocellular red nucleus. Together with the parvocellular red nucleus, it makes up the red nucleus.

Parvocellular neurons

.

The parvocellular neurons are sensitive to parvocellular neurons, and are more capable of discriminating fine details than their magnocellular counterparts.

Hypothalamic neuroendocrine cells that synthesize oxytocin OT and vasopressin AVP can be categorized into two major cell types, namely magnocellular and parvocellular neurons. In addition to the previously known differences in morphology, connectivity, and electrophysiological properties, recent studies highlight fundamentally different functions and genetic compositions of these cells. Parvocellular OT neurons have recently been implicated in pain perception and processing, regulation of OT release during fear, and promotion of social behavior in female rats following gentle touch. Despite the vast knowledge of parvocellular OT neurons, surprisingly little is known about parvocellular AVP cells. The activity of AVP receptor-expressing presympathetic cells in the paraventricular nucleus of the hypothalamus is regulated by somato-dendritically released AVP from nearby magnocellular AVP cells. However, the contribution of actual parvocellular AVP neurons to this phenomenon remains questionable. Here we summarize the current body of knowledge about the neuroanatomy and functional relationship of the magnocellular and parvocellular OT and AVP systems.

Parvocellular neurons

Parvocellular neurosecretory cells are small neurons that produce hypothalamic releasing and inhibiting hormones. The cell bodies of these neurons are located in various nuclei of the hypothalamus or in closely related areas of the basal brain, mainly in the medial zone of the hypothalamus.

Restraint stress enhances excitatory but not inhibitory synaptic transmission in the paraventricular hypothalamic nucleus of the rat. Thus, restraint stress selectively enhances excitatory input to the paraventricular nucleus of the rat, most likely via a presynaptic mechanism.

The paraventricular nucleus of the hypothalamus PVH , located in the ventral diencephalon adjacent to the third ventricle, is a highly conserved brain region present in species from zebrafish to humans. The PVH is composed of three main types of neurons, magnocellular, parvocellular, and long-projecting neurons, which play imperative roles in the regulation of energy balance and various endocrinological activities.

This also resulted in reduction in the number of neurons in the parvocellular and magnocellular layers. They are termed "magnocellular" since they are characterized by their relatively large size compared to parvocellular cells. The particular pathway used for color discrimination is the parvocellular pathway. The koniocellular layers are interspersed between the magnocellular and parvocellular layers.
