Derived from TELENCEPHALON, cerebrum is composed of a right and a left hemisphere. Each contains an outer cerebral cortex and a subcortical basal ganglia. The cerebrum includes all parts within the skull except the MEDULLA OBLONGATA, the PONS, and the CEREBELLUM. Cerebral functions include sensorimotor, emotional, and intellectual activities.
A stack of flattened vesicles that functions in posttranslational processing and sorting of proteins, receiving them from the rough ENDOPLASMIC RETICULUM and directing them to secretory vesicles, LYSOSOMES, or the CELL MEMBRANE. The movement of proteins takes place by transfer vesicles that bud off from the rough endoplasmic reticulum or Golgi apparatus and fuse with the Golgi, lysosomes or cell membrane. (From Glick, Glossary of Biochemistry and Molecular Biology, 1990)
Projection neurons in the CEREBRAL CORTEX and the HIPPOCAMPUS. Pyramidal cells have a pyramid-shaped soma with the apex and an apical dendrite pointed toward the pial surface and other dendrites and an axon emerging from the base. The axons may have local collaterals but also project outside their cortical region.
A curved elevation of GRAY MATTER extending the entire length of the floor of the TEMPORAL HORN of the LATERAL VENTRICLE (see also TEMPORAL LOBE). The hippocampus proper, subiculum, and DENTATE GYRUS constitute the hippocampal formation. Sometimes authors include the ENTORHINAL CORTEX in the hippocampal formation.

The rostral part of the frontal lobe, bounded by the inferior precentral fissure in humans, which receives projection fibers from the MEDIODORSAL NUCLEUS OF THE THALAMUS. The prefrontal cortex receives afferent fibers from numerous structures of the DIENCEPHALON; MESENCEPHALON; and LIMBIC SYSTEM as well as cortical afferents of visual, auditory, and somatic origin.
A bibliographic database that includes MEDLINE as its primary subset. It is produced by the National Center for Biotechnology Information (NCBI), part of the NATIONAL LIBRARY OF MEDICINE. PubMed, which is searchable through NLM's Web site, also includes access to additional citations to selected life sciences journals not in MEDLINE, and links to other resources such as the full-text of articles at participating publishers' Web sites, NCBI's molecular biology databases, and PubMed Central.
Specialized junctions at which a neuron communicates with a target cell. At classical synapses, a neuron's presynaptic terminal releases a chemical transmitter stored in synaptic vesicles which diffuses across a narrow synaptic cleft and activates receptors on the postsynaptic membrane of the target cell. The target may be a dendrite, cell body, or axon of another neuron, or a specialized region of a muscle or secretory cell. Neurons may also communicate via direct electrical coupling with ELECTRICAL SYNAPSES. Several other non-synaptic chemical or electric signal transmitting processes occur via extracellular mediated interactions.
The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.

The formation of an area of NECROSIS in the CEREBRUM caused by an insufficiency of arterial or venous blood flow. Infarcts of the cerebrum are generally classified by hemisphere (i.e., left vs. right), lobe (e.g., frontal lobe infarction), arterial distribution (e.g., INFARCTION, ANTERIOR CEREBRAL ARTERY), and etiology (e.g., embolic infarction).

- After the development of achromatic microscopes and better staining methods in the 19th century, botanist Matthias Jakob Schleiden in 1838 proposed that cells were the fundamental building blocks of plant life. (sfn.org)
- But neurons were less visible than other cells even to the improved microscopes of the early 19th century. (sfn.org)
- However, cell theory struggled to explain neurons as they are specialized cells and more complex in structure than cells of other tissues. (asu.edu)
- Using that method, researchers could not see neurons very well, as the penetration of the stain into the neurons varied depending on the size of the cell. (asu.edu)
- In smaller neurons, scientists saw only two cellular structures, the nucleus in the center of the cell that contains genetic material, and the cell wall encasing the cell. (asu.edu)
- Silver chromate primarily clusters around the cell membrane, staining the entire neuron cell black, while earlier methods only stained parts of cells. (asu.edu)
- A few simple dyes helped improve cell visibility , but early microscopists lacked stains that could elucidate cell structure. (visionlearning.com)

- One, known as parvalbumin-expressing (PV) interneurons, targets neurons' cell bodies. (scitechdaily.com)
- When embedded in neurons' cell membranes, channelrhodopsin controls the flow of ions in and out of the neurons, altering their electrical activity. (scitechdaily.com)
- If the target cell is a neuron, the action potential sweeps along its fibre. (encyclopedia.com)
- Growing evidence suggests that proteins that help build microtubule structures during cell division are also involved in building and remodeling the complex cytoskeletons of neurons. (biomedcentral.com)
- These changes in shape are not due to alterations in cell fate or neuron layer type. (biomedcentral.com)
- Sherrington reasoned that, since "there does not exist actual confluence of the conductive part of one cell with the conductive part of the other, … there must be a surface of separation," or a "nexus between neurone and neurone in the reflex arc. (cbhd.org)
- The cell body, or the soma, is the central part of the neuron. (newworldencyclopedia.org)
- The frequency of fusion events (demonstrated by double labelling with EGFP and human Golgi Zone) between the two cell populations was significantly increased by the addition of TNF-alpha and/or IFN-gamma to co-cultures when compared with the absence of cytokines (Figure 6C). (nih.gov)
- Those variations in visibility between neurons made the hematoxylin staining method unreliable. (asu.edu)
- One method that has been available for over a century is to use metal particles to stain some of the cells. (elifesciences.org)
- Golgi staining method was very, very sparse. (coursera.org)
- Now referred to as the Golgi method, the protocol has been refined over the years and proved instrumental for many groundbreaking advances in neurobiology. (phys.org)
- In the 1990s, the development of this gentler and more precise microscopy method improved scientists' ability to probe neurons' activity and anatomy. (the-scientist.com)
- His work on pellagra early and psammomas later brought him great recognition but the development of the Golgi method to stain neuroglia achieved for him permanent fame. (scribd.com)
- In these mutants, almost all neurons in the dentate gyrus are arrested at a pseudoimmature state at the molecular and electrophysiological levels, a phenomenon defined as "immature dentate gyrus (iDG). (hindawi.com)

Medium spiny n2
- Medium spiny neurons of the striatum show a high degree of structural plasticity that is modulated by dopamine through unknown signaling mechanisms. (jneurosci.org)
- Here, we demonstrate that overexpression of dopamine D2 receptors in medium spiny neurons increases their membrane excitability and decreases the complexity and length of their dendritic arbors. (jneurosci.org)
- Golgi read medicine at the University of Pavia, where, together with Giulio Bizzozero and Enrico Sertoli, he studied under Eusebio Oehl, distinguished as the first in Pavia to develop systematically studies of microscopic anatomy and histology. (encyclopedia.com)
- Neutral red (toluylene red, Basic Red 5, or C.I. 50040) is a eurhodin dye used for staining in histology. (wikipedia.org)
