A corticothalamic-projecting glutamatergic neuron that is located in L6 and lower L5 of the primary motor cortex, with a pyramidal morphology and mostly untufted apical dendrites terminating in midcortical layers. CT VAL/VM (ventroanterior-ventrolateral complex/ventromedial nucleus) cells have a near tonic firing pattern and are distinguished from L6 IT neurons by a lower inter-spike interval adaptation index.
