Pinealocytes are the main cells contained in the pineal gland, located behind the third ventricle and between the two hemispheres of the brain. The primary function of the pinealocytes is the secretion of the hormone melatonin , important in the regulation of circadian rhythms . [ 1 ]
The pineal gland (also known as the pineal body [1] or epiphysis cerebri) is a small endocrine gland in the brain of most vertebrates.It produces melatonin, a serotonin-derived hormone, which modulates sleep patterns following the diurnal cycles. [2]
Ribbon synapses are found in retinal photoreceptor cells, vestibular organ receptors, cochlear hair cells, retinal bipolar cells, and pinealocytes. The synaptic ribbon is a unique structure at the active zone of the synapse. It is positioned several nanometers away from the pre-synaptic membrane and tethers 100 or more synaptic vesicles. [8]
The function of the epithalamus is to connect the limbic system to other parts of the brain. The epithalamus also serves as a connecting point for the dorsal diencephalic conduction system, which is responsible for carrying information from the limbic forebrain to limbic midbrain structures.
Neurosecretion is the release of extracellular vesicles and particles from neurons, astrocytes, microglial and other cells of the central nervous system.These neurohormones, produced by neurosecretory cells, are normally secreted from nerve cells in the brain that then circulate into the blood.
NIF provides access to resources that are relevant to neuroscience, search strategies tailored to the field, and access to content that is traditionally "hidden" from web search engines. The Framework is an inventory of neuroscience databases, annotated and integrated with a unified system of biomedical terminology (i.e., NeuroLex). NIF ...
Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...
In neuroscience, Dale's principle (or Dale's law) is a rule attributed to the English neuroscientist Henry Hallett Dale. The principle basically states that a neuron performs the same chemical action at all of its synaptic connections to other cells, regardless of the identity of the target cell. However, there has been disagreement about the ...
