Topic: thalamocortical projections

The higher-order thalamus has an important role for cortico-thalamo-cortical information processing. A precise knowledge of the anatomical structure of thalamocortical projections is necessary to better understand this kind of information processing compared to direct cortico-cortical routes. Therefore, neurons in the thalamus of mice were retrogradely labelled by injecting cholera toxin subunit B conjugates into the primary somatosensory cortex and the motor cortex. The stained neurons were automatically detected in the microscopic images and then assigned to corresponding anatomical structur
