...The main components of the basal ganglia are the striatum, pallidum, substantia nigra, and subthalamic nucleus. The largest component, the striatum, receives input from many brain areas but sends output only to other components of the basal ganglia. The pallidum receives its most important input from the striatum (either directly or indirectly), and sends inhibitory output to a number of motor-related areas, including the part of the thalamus that projects to the motor-related areas of the cortex. The substantia nigra consists of two parts, one that functions similarly to the pallidum, and another that provides the source of dopamine input to the striatum. The subthalamic nucleus receives input mainly from the striatum and cortex, and projects to the pallidum. Each of these areas has a complex internal anatomical and neurochemical organization.

I'm not certain what you mean by the neuroanatomy motor loop, but it sounds like you are refering to the motor/sensory feedback loops of the cerebellum and ganglia in orchestrating motor control, coordination and monitoring body position by sending out motor control signals and receiving feedback in the form of sensory signals which continually compensates and adjusts the motor signals to maintain balance and coordination of the muscles involved. This motor/sensory feedback loop works in parallel with the basal ganglia which receives input signals from the cerebral cortex to the striatum, to the globus pallidus, to the substantia nigra, which returns signals to the cerebral cortex by way of the thalamus. Through this loop, the basal ganglia maintains muscle tone, by coordination of muscle extension and contraction, to stabilize the joint in one position, or to relax muscle tone during the intitiation of a movement. Both functions are necessary to maintain balance and smooth coordination of movement. |

is the basal ganglia linked to is the basal ganglia linked to
the hypothalamus in some way?
because i know that the basal
ganglia is affected by THC in
Marijuana because the basal
ganglia has cannabinoid
receptors.
and the THC effects the users
appetite
but the hypothalamus is in
charge of appetite, correct?
and the basal ganglia is in
charge of muscle movement,
correct?
so how are these connected to
affect the appetite when THC
is involved?
thanks

im not sure if there is any connection between them but all I know is that the basal ganglia has direct connections with the thalamus itself and subthalamic nuclei |

A quick search on google provided me a bit of information, but I can offer no first hand information. Your question caught my interest because I have a daughter with ganglioneuroblastoma (a pediatric cancer). The word "ganglia" caught my eye. From what I saw in medical journals, "insult" means damage. This could be from lack of oxygen prior to or during birth, or other causes. Damage to this area of the brain can cause a wide variety of problems, from minor speech problems to Parkinson's. I will say a prayer for your daughter. Remember, babies can heal miraculously well because their systems are still developing! Best of luck to you and your daughter. |
