[6] [3] MSF, which is a liquid at room temperature, has a vapor pressure of 19.2 mmHg, slightly more volatile than water which has a vapor pressure of 18.8 mmHg at 21 °C. This vapor has an LCt 50 (lethal concentration, 50% death rate in a given time) in rats of between 4 and 5 parts per million (ppm) during one hour of exposure or between 1 ...
The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
Other lesions in the mouse, particularly in the striatum 6-OHDA, show a variable sensitivity to levodopa and shows the difference in lesion severity based on location. In a study with rats, using intracranial self-stimulation implanted in the medial forebrain bundle, rats treated with nicotine and methamphetamine showed an increased speed at ...
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
This development section covers changes in brain structure over time. It includes both the normal development of the human brain from infant to adult and genetic and evolutionary changes over many generations. Neural development in humans; Neuroplasticity – changes in a brain due to behavior, environment, aging, injury etc.
There are many cisterns in the brain with several large ones noted with their own name. At the base of the spinal cord is another subarachnoid cistern: the lumbar cistern which is the site for a lumbar puncture. Some major subarachnoid cisterns: Cisterna magna also called cerebellomedullary cistern - the largest of the subarachnoid cisterns.

Subfornical organ of a mouse. In this photomicrograph, the subfornical organ (arrow) is located on the undersurface of the fornix in the upper part of the third ventricle. The cells in this coronal section of the brain were colored with a bluish dye ("Nissl stain"). The thalamus is at the bottom of the photo. The bar at the lower right ...
