Chronic solvent-induced encephalopathy (CSE) is a condition induced by long-term exposure to organic solvents, often—but not always—in the workplace, that lead to a wide variety of persisting sensorimotor polyneuropathies and neurobehavioral deficits even after solvent exposure has been removed.
Red softening is one of the three types of cerebral softening. As its name suggests, certain regions of cerebral softening result in a red color. This is due to a hemorrhagic infarct, in which blood flow is restored to an area of the brain that was previously restricted by an embolism. This is termed a "red infarct" or also known as red ...
The first anatomical hemispherectomy was performed and described in 1928 by Walter Dandy.This was done as an attempt to treat glioma, a brain tumor. [1] The first known anatomical hemispherectomy performed as a treatment for intractable epilepsy was in 1938 by Kenneth McKenzie, a Canadian neurosurgeon. [2]
Normal and red neurons. A "red neuron" (acidophilic or "eosinophilic" neuron) is a pathological finding in neurons, generally of the central nervous system, indicative of acute neuronal injury and subsequent apoptosis or necrosis. Acidophilic neurons are often found in the first 12–24 hours after an ischemic injury such as a stroke. Since ...
A related version of the McCollough effect also occurs with a single color and orientation. For example, induction with only a red horizontal grating makes a black-and-white horizontal test grating appear greenish whereas a black-and-white vertical test grating appears colorless (although there is some argument about that).
Memory erasure has been shown to be possible in some experimental conditions; some of the techniques currently being investigated are: drug-induced amnesia, selective memory suppression, destruction of neurons, interruption of memory, reconsolidation, [1] and the disruption of specific molecular mechanisms.
The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. [1]
This was later confirmed by Paul Divry, who showed that plaques that are stained with the dye Congo Red show the optical property of birefringence, [13] which is characteristic of amyloids in general. [14] In 1911, Teofil Simchowicz introduced the term 'senile plaques' to denote their frequent presence in the brains of older individuals.
