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. [22]
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 ...
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.
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 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.
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 ...
The caudate nucleus is one of the structures that make up the corpus striatum, which is part of the basal ganglia in the human brain. [1] Although the caudate nucleus has long been associated with motor processes because of its role in Parkinson's disease, [2] [clarification needed] [3] it also plays important roles in nonmotor functions, such as procedural learning, [4] associative learning ...
The striatum (pl.: striata) or corpus striatum [5] is a cluster of interconnected nuclei that make up the largest structure of the subcortical basal ganglia. [6] The striatum is a critical component of the motor and reward systems; receives glutamatergic and dopaminergic inputs from different sources; and serves as the primary input to the rest of the basal ganglia.
