A five loop division based on primary cortical targets has been described as follows: [11] A motor circuit originating in the supplementary motor area , motor cortex , and somatosensory cortex , which in turn projects to the putamen, which projects to the ventrolateral GPi and caudolateral SNr, before returning to the cortex via the ventralis ...
Cortico-striato-thalamocortical circuit, also known as cortico-basal ganglia-thalamo-cortical loop, a type of neural circuit in the brain Combined Security Transition Command – Afghanistan Topics referred to by the same term
The cortico-basal ganglia-thalamo-cortical loop has been traditionally associated with reward-learning, and though has also been noted by some researchers to have a modulatory effect on thalamocortical network functioning, this is due to inherent activation of the premotor areas connecting the VA nucleus with the cortex.

A major output from the cortex, with axons from most of the cortical regions connecting to the striatum, is called the corticostriatal connection, part of the cortico-basal ganglia-thalamo-cortical loop, or basal ganglia loop in short. [1] In the primate most of these axons are thin and unbranched.
Cortico-basal ganglia-thalamo-cortical loop [ edit ] The dopaminergic pathways that project from the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) into the striatum (i.e., the nigrostriatal and mesolimbic pathways, respectively) form one component of a sequence of pathways known as the cortico-basal ganglia-thalamo ...
Thalamo-cortico-thalamic circuits consist of looped neural pathways that connect the thalamus to the cerebral cortex, and connect the cerebral cortex back to the thalamus. Some researchers propose that such circuits allow the brain to obtain data on its own activity.
For more than 50 years, a spinal fusion has been to the go-to surgery for herniated discs. But a new procedure may offer an alternative. New back surgery gaining popularity to alleviate pain [Video]
The left side of Fig.1 shows a region of the prefrontal cortex receiving multiple inputs from other regions, as cortico-cortical activity. The input from B is the strongest of these. The right side of Fig. 1 shows the input signals also being fed to the basal ganglia circuitry.
