  • Title: [Thalamic and cortical connections of the globus pallidus in the cat].
    Author: Makoev VU.
    Journal: Arkh Anat Gistol Embriol; 1981 Jun; 80(6):5-11. PubMed ID: 7283770.
    Abstract:
    Two series of experiments have been performed on cats: the first -- with destruction of various parts in the globus pallidus, the second -- with destruction of the telencephalic cortex. The experimental material has been treated by Nauta -- Gygax's, Fink -- Heimer's, Kawamura -- Niimi's methods. Localization of the destructed focus has been proved in the preparations stained after Nissl. As demonstrated the results of the investigation, together with the medial, the lateral segment of the globus pallidus has some pallido-thalamic fibres. Both segments of the globus pallidus have direct connections with the telencephalic cortex. According to the degree of how these connections are expressed, the motor cortex occupies the first place, the sensory cortex -- the second and the temporal area cortex -- the third place. There is a definite distribution (topics) of the globus pallidus connections with the thalamus, the subthalamic nucleus and the telencephalic cortex. There is a definite correspondence of the cortico-pallidal and pallido-cortical pathways consisting in the fact that the senso-motor cortical area has the greatest number of direct connections with the globus pallidus. That the globus pallidus possesses complex connections with the thalamic structures and with the telencephalic cortex speaks in favour of its important role in the cerebral integrative activity.
