Document Summary

Describe each of the six layers of mammalian isocortex, including the typical neurons found in each and their input/output relationships to other brain regions. Not a lot of neurons in this layers, but lots of apical dendritic tufts and horizontally-oriented axons of pyramidal neurons as well as glial cells. b. Cajal-retzius and spiny stellate neurons can also be found in layer 1. Contains axonal and dendritic synapses it"s the origin of function since it outputs to the neocortex: layer 3 aka outer pyramidal cell layer: has small and medium pyramidal and non-pyramidal neurons. The non-pyramidal neurons have vertically oriented intracortical axons. Principle source cortico-cortical nts and main target of interhemispheric afferent cells along with layer i and ii. It basically receives info from other areas of the neocortex and passes them along to other cortical columns. What are the inputs and outputs for layers 4-6?: layer 4 aka inner granular layer: densely packed stellate and pyramidal neurons.
