A commissure connects the two cerebral hemispheres at the same levels. Examples are the posterior commissure and the corpus callosum. A decussation is a connection made by fibres that cross at different levels obliquely , such as the sensory decussation.
Examples of a fascicle are the subthalamic fasciculus and the lenticular fasciculus. The nerve fibers in the central nervous system can be categorized into three groups on the basis of their course and connections. The tracts that connect cortical areas within the same hemisphere are called association tracts. Among their roles, association tracts link perceptual and memory centers of the brain.
Through these nerves visual spirits are conveyed to the pupils. Many medieval anatomists devised elaborate theories of how the nerves created emotions and sensations in different parts of the body through their attachment to principal organs and members. The writings of the Renaissance physicians reflect a mixture of ancient and medieval beliefs about the nervous system as well as new knowledge from anatomical dissections. In , Alessandro Achillini could still write, much in the spirit of Galen, that "the nerves are light to receive the spirit and thin in order to offer swift and easy passage to the spirit and flexible to serve the members.
In the late fifteenth century, for example, Alessandro Be nedetti might still subscribe to the idea of spiritus , but his physical description of the nervous system was considerably more precise and detailed because of his examinations of cadavers.
Similarly, his contemporary Leonardo da Vinci initially relied quite heavily on the writings of Avicenna and others in describing the nervous system and believed the heart to be the first organ. From his studies he concluded that the spinal cord was the center of life. Humira, nerve damage, scaitica big frustration - Autoimmune Disorders Community.
