If the data to be stored is longer than the number of characters allowed, the data is truncated. For example, if a column is defined as char(10) and the value This is a really long character string is stored into the column, SQL Server truncates the character string to This is a . The char data type is a fixed-length data type when the NOT NULL clause is specified.
Freebase(0.00 / 0 votes)Rate this definition: Basal ganglia. The basal ganglia are a group of nuclei of varied origin in the brains of vertebrates that act as a cohesive functional unit. They are situated at the base of the forebrain and are strongly connected with the cerebral cortex, thalamus and other brain areas.
It is now known that the basal ganglia do not originate a separate motor pathway. Instead, they influence and modulate the activity of motor cortex and the descending motor pathways in ways that cause distinct symptoms when different basal ganglia structures are damaged.asal ganglia dysfunction causes a set of symptoms that are quite different from damage to descending motor pathways, and thus the basal ganglia were at one time considered to form an âextrapyramidal motor systemâ that was distinct from the pyramidal tract pathways.
