Golgi's method is a silver staining technique that is used to visualize nervous tissue under light microscopy. The method was discovered by Camillo Golgi , an Italian physician and scientist , who published the first picture made with the technique in 1873. [ 1 ]
The Purkinje cell protein 4 is markedly immunoreactive in the Purkinje cells of the human cerebellum. From top to bottom 40X, 100X and 200X microscopic magnifications. The immunohistochemistry was performed based on published methods. [11] Microcircuitry of the cerebellum. Excitatory synapses are denoted by (+) and inhibitory synapses by (-).
The human cerebral cortex divided into Brodmann areas on the basis of cytoarchitecture.. Cytoarchitecture (from Greek κύτος 'cell' and ἀρχιτεκτονική 'architecture'), also known as cytoarchitectonics, is the study of the cellular composition of the central nervous system's tissues under the microscope.
Nervous tissue, also called neural tissue, is the main tissue component of the nervous system.The nervous system regulates and controls body functions and activity. It consists of two parts: the central nervous system (CNS) comprising the brain and spinal cord, and the peripheral nervous system (PNS) comprising the branching peripheral nerves.
The area provides a reference unit, for example in reference ranges for urine tests. [3]Used for grading of soft tissue tumors: Grading, usually on a scale of I to III, is based on the degree of differentiation, the average number of mitoses per high-power field, cellularity, pleomorphism, and an estimate of the extent of necrosis (presumably a reflection of rate of growth).
In cellular neuroscience, the soma (pl.: somata or somas; from Greek σῶμα (sôma) 'body'), neurocyton, or cell body is the bulbous, non-process portion of a neuron or other brain cell type, containing the cell nucleus.
A reconstruction of a pyramidal cell. Soma and dendrites are labeled in red, axon arbor in blue. (1) Soma, (2) Basal dendrite, (3) Apical dendrite, (4) Axon, (5) Collateral axon. One of the main structural features of the pyramidal neuron is the conic shaped soma, or cell body, after which the neuron is named.
One small study found that men have more white matter than women both in volume and in length of myelinated axons, and that volume and length reduced with age. (This study only included 36 participants. [6]) At the age of 20, the total length of myelinated fibers in men is 176,000 km while that of a woman is 149,000 km.
