The first reports of Covid-19 affecting the central nervous system appeared on the preprint server medRxiv in late February, posted by neurologists in Wuhan, China, where the outbreak started. This is a clear, watery liquid produced in the ventricles. It communicates with the fourth at the base of the brain through a tube called the cerebral aqueduct. The two lateral ventricles in the cerebral hemispheres communicate with a third located in the center of the brain.

[140] The energy consumption of the brain does not vary greatly over time, but active regions of the cortex consume somewhat more energy than inactive regions: this fact forms the basis for the functional brain imaging methods PET and fMRI. The left and right sides of the brain appear symmetrical, but they function asymmetrically.
[41][40] The reticular formation, a network of nuclei of ill-defined formation, is present within and along the length of the brainstem. In Detroit, the Covid-19 patient who developed a rare form of encephalitis is now recovering in a rehabilitation facility. Underneath the cerebral cortex are several important structures, including the thalamus, the epithalamus, the pineal gland, the hypothalamus, the pituitary gland, and the subthalamus; the limbic structures, including the amygdala and the hippocampus; the claustrum, the various nuclei of the basal ganglia; the basal forebrain structures, and the three circumventricular organs. The hypothalamus leads on to the pituitary gland. A dural sinus is a channel that lies between…. Plus: What it means to “flatten the curve,” and everything else you need to know about the coronavirus. Without it, you couldn’t breathe or walk. 5th ed. Cells detach from the crest and migrate in a craniocaudal (head to tail) wave inside the tube. From here, it passes through to the cochlear nuclei, the superior olivary nucleus, the medial geniculate nucleus, and finally the auditory radiation to the auditory cortex. Mayo Clinic, Rochester, Minn. Nov. 2, 2017. This amazing organ acts as a control center by receiving, interpreting, and directing sensory information throughout the body.

No one yet knows exactly why this happens; why the virus seems to stop in the nose rather than climbing into their brains like in Perlman’s mice.

It’s a rare complication known to occasionally accompany influenza and other viral infections, though usually in children. [214][215], Other animals, including whales and elephants have larger brains than humans. Averaging a pound at birth, the brain grows to approximately three pounds by adulthood. On the computer screen, white lesions dotted the gray cross-sectioned landscape—each one filled with dead and dying neurons in regions that normally relay sensory signals, regulate alertness, and access memories. The brainstem continues below this as the spinal cord,[40] protected by the vertebral column. [34] The anterior and posterior lobes are connected in the middle by the vermis.
[30] The largest component is the striatum, others are the globus pallidus, the substantia nigra and the subthalamic nucleus. This nerve transmits to the neural circuitry of the olfactory bulb from where information is passed to the olfactory cortex. http://www.nccn.org/professionals/physician_gls/f_guidelines.asp. [33], The cerebellum is divided into an anterior lobe, a posterior lobe, and the flocculonodular lobe. Hu's team published their findings online April 10 in JAMA Neurology. Three days later he visits another clinic, looking for relief from his worsening headache and sore throat. [175] Rare prion diseases including Creutzfeldt–Jakob disease and its variant, and kuru may also affect the brain.
