# ATM Adaptation Layer ( AAL ) and

# ATM Layer correspond roughly to the OSI Data Link Layer

# Physical Layer, equivalent to OSI Physical Layer

# The Layer 2 ( Data Link Layer ) PDU is the frame

# The Layer 3 ( Network Layer ) PDU is the packet

# The Layer 4 ( Transport Layer ) PDU is the segment for TCP, or the datagram for UDP

# Layer I, the Molecular layer, contains few scattered neurons and consists mainly of extensions of apical dendritic tufts of pyramidal neurons and horizontally oriented axons, as well as glial cells.

# Layer II, the External granular layer, contains small pyramidal neurons and numerous stellate neurons.

# Layer III, the External Pyramidal layer, contains predominantly small and medium-size pyramidal neurons, as well as non-pyramidal neurons with vertically oriented intracortical axons ; layers I through III are the main target of interhemispheric corticocortical afferents, and layer III is the principal source of corticocortical efferents.

# Layer IV, the Internal Granular layer, contains different types of stellate and pyramidal neurons, and is the main target of thalamocortical afferents from thalamus type C neurons.

# Layer V, the Internal Pyramidal layer, contains large pyramidal neurons ( such as the Betz cells in the primary motor cortex ); it is the principal source of subcortical efferents, as such, there are large pyramidal cells which give rise to axons leaving the cortex and running down through the basal ganglia, the brain stem and the spinal cord.

# Layer VI, the Polymorphic or Multiform layer, contains few large pyramidal neurons and many small spindle-like pyramidal and multiform neurons ; layer VI sends efferent fibers to the thalamus, establishing a very precise reciprocal interconnection between the cortex and the thalamus.
