dictyosome, Golgi apparatus, Golgi body, Golgi complex - a netlike structure in the cytoplasm of animal cells (especially in those cells that produce secretions) sac - a structure resembling a bag in an animal bleb, blister - (pathology) an elevation of the skin filled with serous fluid fo...
High energy consumption by brain cells called neurons causes them to spew forth a lot of trash, which floats around the brain and interferes with regular brain function. This waste is mainly made up of leftover proteins, which can aggregate into brain-toxic clumps if left unchecked. The decrea...
Gray matter exists all throughout the various parts of the brain (as well as in the spinal cord); it consists of different types of cells, such as neurons. However, the brain also contains white matter, which comprises nerve fibers that connect the gray matter. The black component is ...
bilocular capsule - a capsule divided into two cells or compartments boll - the rounded seed-bearing capsule of a cotton or flax plant siliqua, silique - narrow elongated seed capsule peculiar to the family Cruciferae peristome - (botany) fringe of toothlike appendages surrounding the mouth of ...
Since 1 in.3 of brain matter contains millions of brain cells and hundreds of millions of synapses or neural connections, Rushton hypothesized that these brain size differences help to explain why the races differ in average IQ. Similarly, Jensen (1998, p. 443) calculated an “ecological ...
biomedical brain research has evolved according to time trends. In 1791, Luigi Galvani observed convulsions in frogs’ legs when they were in contact with a metal dissecting knife. This experiment was the first to show that an electric current can flow among living muscles, nerves, and cells an...
chemical nature, distribution and interaction of the tracer/radiopharmaceutical utilised with the cellular system which requires investigation: the thyroid cells with sodium iodide, the recticular endothelial cells with colloidal particles, the adrenal medulla cells with metaiodobenzylguanidine, and so on....
Calcitonin gene-related peptide: detailed immunohistochemical distribution in the central nervous system. In the midbrain a large cluster of cells was contained in the peripeduncular area ventral to the medial geniculate body. In the hindbrain cholinergic ......
cells communicated with neurons using distinct pathways (Fig.3d). Relative abundance had no significant difference in most neuron types between female and male brain samples (Extended Data Fig.1f). However, the proportion of peptidergic neurons in male spiders was higher than that in female spiders...
One French study identified the dysexecutive syndrome in 15/45 (33%) patients with severe COVID-19 infection2. Another Chinese study recruited 29 patients (after hospitalisation) and reported cognitive dysfunction after their recovery3. A third Swiss study with 121 patients also detected executive ...
