• Parkinson's
  • The exact function of the basal ganglia is something that is still being studied and observed, though it has been determined that the area plays some part in disease, including Parkinson's Disease and Huntington's Disease. (reference.com)
  • Just watch a person with a typical basal ganglion affliction, such as Parkinson's disease, characterized by difficulty in starting or stopping the walking sequence, and realize how profundly these nuclei are involved in daily life. (cerebromente.org.br)
  • New research is showing how the basal ganglia, deep inside the brain below the cortex, are important in learning from feedback, in the formation of good and bad habits, and even in brain disorders as diverse as Parkinson's disease, ADHD, and addiction. (dana.org)
  • The muscle rigidity, tremor at rest, and slowness in initiation and execution of movement that are the cardinal motor symptoms of Parkinson's disease are attributed to a reduction in dopaminergic activity in the basal ganglia motor areas, particularly the putamen, due to gradually reduced innervation from SNc. (wikipedia.org)
  • Also, several major degenerative diseases of the basal ganglia, including Parkinson's disease and Huntington's disease, are specific to humans, although "models" of them have been proposed for other species. (wikipedia.org)
  • ganglia's
  • Reflexes deserve respect, writes the author, and understanding how people differ in learning from positive or negative feedback may have implications for education as well as for treating diseases in which the basal ganglia's systems go awry. (dana.org)
  • inhibits
  • Along with the cerebellum, the basal ganglia controls movement and posture, adjusting the body to do certain things, as well as inhibits unwanted movement. (dmoztools.net)
  • Behavior
  • In addition to their role in control of movement and posture, it now appears that the basal ganglia also play a more complex (cognitive) aspects of behavior and may be involved in limbic functions. (cerebromente.org.br)
  • Of course, this machinery is inordinately intricate and complex, The more a behavior is ingrained, the more its neural representations in the basal ganglia are strengthened and honed. (dana.org)
  • involvement
  • One possible factor could be the natural accumulation of iron in the basal ganglia, causing neurodegeneration due to its involvement in toxic free-radical reactions. (wikipedia.org)
  • brain
  • The basal ganglia plays a role in a number of functions in the brain, including involuntary motor control and some cognitive functions. (reference.com)
  • The term is occasionally applied to certain nuclear groups within the brain or spinal cord, such as the basal ganglia . (thefreedictionary.com)
  • Like most parts of the brain, the basal ganglia consist of left and right sides that are virtual mirror images of each other. (wikipedia.org)
  • The basal ganglia form a major brain system in all species of vertebrates, but in primates (including humans) there are special features that justify a separate consideration. (wikipedia.org)
  • indicates
  • Damage to the basal ganglia produces severe deficit s in motor ability, but the neuron al activation in the basal ganglia indicates that they do not specfically direct the muscular movements, nor are they involved in stimulus-triggered movement . (everything2.com)
  • motor
  • It seems to be generally agreed that the basal ganglia have something to do with the creation and execution of motor plans. (cerebromente.org.br)
  • The basal ganglia are associated with a variety of functions including: control of voluntary motor movements, procedural learning, routine behaviors or "habits" such as teeth grinding, eye movements, cognition, and emotion. (wikipedia.org)
  • Experimental studies show that the basal ganglia exert an inhibitory influence on a number of motor systems, and that a release of this inhibition permits a motor system to become active. (wikipedia.org)
  • distinct
  • The basal ganglia have a limbic sector whose components are assigned distinct names: the nucleus accumbens, ventral pallidum, and ventral tegmental area (VTA). (wikipedia.org)
  • voluntary
  • The direct pathway of movement is a neuronal circuit within the central nervous system (CNS) through the basal ganglia which facilitates the initiation and execution of voluntary movement. (wikipedia.org)
  • loop
  • The loop was originally proposed as a part of a model of the basal ganglia called the parallel processing model, which has been criticized and modified into another model called the center surround model. (wikipedia.org)
