BASIAL GANGLIA
Objectives: Define basal ganglia and describe the parts, describe the main connections and functions, describe the function and the disorders of basal ganglia
The main function of the basal ganglia is to provide a feedback mechanism for the selection and initiation of voluntary movement. They way it does that is it provides an input to the thalamus which acts as an inhibitory input to the lateral ventricle of the thalamus which then projects an excitaroty input to the motor cortex. Its motor input loop is essentially how voluntary movement is selected and initiated. So if anything affects this loop with either dampen or enhance voluntary movement (Parkinsons/Huntingson diseases).
The basal ganglia is a series of interconnected …show more content…
Putamen is next to the caudate which is separated by the internal capsule. The caudate is responsible for telling the brain that there is something wrong and something should be done to fix it. Caudate can be used in many ways but if its is overused you have conditions like Obsessive Compulsive Disorder. Putamen is involved with learning abilities such as playing the piano or riding a bike. Behind the putamen lays the globus pallidus which essentially acts as the output structure of the basal …show more content…
These neurons project onto the inhibitory neurons which is then projected into the subthalamic nucleus. The STN are the only nucleus that contains the excitatory glutamatergic neurons which goes on to project onto the GPi. Also in the striatum neurons, it projects D1 receptors which goes straight to the GPi, therefore direct. The GPi has the final say on telling the thalamus what type of movement and how much movement to generate. After the information being fed to the thalamus, it is then projected back to the cortex. The cortex information is then projected back to the striatum to form the ‘motor
