Astrocytes (green) in the context of neurons (red) in a mouse cortex cell culture 23-week-old fetal brain culture human astrocyte Astrocytes (red-yellow) among neurons (green) in the living cerebral cortex. Astrocytes are a sub-type of glial cells in the central nervous system. They are also known as astrocytic glial cells.
The hippocampus is a structure in the brain that has been associated with various memory functions. It is part of the limbic system , and lies next to the medial temporal lobe. It is made up of two structures, the Ammon's Horn , and the Dentate gyrus , each containing different types of cells .
Magnetic resonance imaging (MRI) is a non-invasive imaging technique that uses strong magnetic fields and radio waves to generate detailed images of the brain's anatomy and function. [24] It can provide information about blood flow, oxygenation levels, and structural characteristics of the neurovascular unit.
The main functions of the frontal lobe are to control attention, abstract thinking, behaviour, problem-solving tasks, and physical reactions and personality. [25] [26] The occipital lobe is the smallest lobe; its main functions are visual reception, visual-spatial processing, movement, and colour recognition.
SGCs are present in the PNS in fewer numbers than other more well-known types of glial cells, like astrocytes, but have been determined to affect nociception because of some of their physiological and pharmacological properties. [21] In fact, just like astrocytes, SGCs have the ability to sense and regulate neighboring neuronal activity. [30]
The main role of astrocytes is to maintain brain homeostasis and neuronal metabolism. When the astrocytes become activated, they begin to respond to damage. [3] Astrocyte activation, known as astrogliosis, responds to neurological trauma, infections, degradations, epilepsy, and tumorigenesis. Each neurological insult plays a major role in ...
Philip Beesley's Astrocyte aims to show that architecture can be more than just ornamental. Built from acrylic, mylar, sensors, custom glasswork, 3D-printed lights and using AI, chemistry and a ...
Monoaminergic systems, i.e., the networks of neurons that use monoamine neurotransmitters, are involved in the regulation of processes such as emotion, arousal, and certain types of memory. It has also been found that monoamine neurotransmitters play an important role in the secretion and production of neurotrophin-3 by astrocytes, a chemical ...
