The cerebral aqueduct is a narrow tube connecting the third and fourth ventricles of the brain. It is named after Franciscus Sylvius and can be affected by congenital stenosis, which causes hydrocephalus.
The ventral tegmental area (VTA) is a group of neurons in the midbrain that produces dopamine for the reward circuitry of the brain. Learn about its anatomy, subdivisions, inputs, outputs, and functions in reward, motivation, and psychiatric disorders.
Learn about the brain structures and functions involved in different types of memory, such as episodic, semantic, procedural, and emotional. Find out how the hippocampus, cerebellum, amygdala, basal ganglia, and other regions contribute to memory encoding, consolidation, and retrieval.
The lobes of the brain are the major identifiable zones of the human cerebral cortex, and they comprise the surface of each hemisphere of the cerebrum. The two hemispheres are roughly symmetrical in structure, and are connected by the corpus callosum. They traditionally have been divided into four lobes, but are today considered as having six lobes each.
Periaqueductal gray is a brain region that plays a role in pain modulation, defensive and reproductive behavior. It is the gray matter around the cerebral aqueduct in the midbrain, and contains enkephalin-producing cells and descending autonomic tracts.
The temporoparietal junction (TPJ) is an area of the brain where the temporal and parietal lobes meet, involved in information processing, perception, language, and theory of mind. Learn about its anatomy, function, disorders, and related terms.
The cerebrum, also known as the telencephalon or endbrain, is the uppermost region of the central nervous system. It contains the cerebral cortex, the hippocampus, the basal ganglia, and the olfactory bulb, and controls voluntary actions, sensory perception, memory, and more.
BP (BP) and the U.S. Coast Guard say about 1,000 barrels of crude oil a day are leaking from the Transocean rig that burned and collapsed in the Gulf of Mexico last week. Coast Guard Rear Admiral ...
