Neocortex L2/3 pyramidal GLU cell
Cajal, S. Ramon y (1911). Reprinted and translated by Swanson and Swanson, Oxford University Press, 1995.
The cell bodies (somas) of these projection neurons are in the (superficial) layers 2/3 of cortex, and have a pyramid shape. These cells release glutamate, the most common excitatory neurotransmitter. These are intratelencephalic (project to the cortex, possibly the other hemisphere, or the basal ganglia) however intratelencephalic cells can also have their cell bodies in deeper cortical layers.

15 Yes Soma AMPA Simultaneous recordings were carried out in visual cortical slices. Assuming open probability of non-NMDA receptor channels to be 0.7, it is suggested that the number of channels available for synaptic transmission between individual pyramidal cells would be 74 (kittens) and 59 (rats)
16 Yes Distal apical dendrite mGluR
