    A novel phasic and restricted basal ganglia thalamocortical subcircuitry model

    D. Kumbhare, G. Weistroffer, M. Baron (Richmond, VA, USA)

    Objective: To advance a novel basal ganglia thalamocortical (BGTC) model that accounts for GPi as a tonic-burst mode regulator of the thalamus and for restricted…
