cortex laminar structure
4 - input layer
often input from thalamus
sublayers
5,6 - output layers (deep)
2,3 - hidden (superficial)
1 - mostly axons
hidden and output neurons have more complex firing properties (White, 1989)
dendrites extend over multiple layers
Crick & Asanuma (1986) discuss connectivity patterns amongst neuron types
in the cortex
a given type of neuron releases only one type of neurotransmitter
[prosem: apparently, can get colocalisation of neurotransmitters on the same neuron under some circumstances]
certainly a neuron can be affected by (i.e. have receptors for) many neurotransmitters
which activates only particular types of postsynaptic receptors
so cortical neurons either send excitatory inputs or inhibitory inputs to other neurons, but not both
N.B. this constraint of excitatory-only or inhibitory-only applies only to the type of output produced by a neuron
they can receive both excitatory and inhibitory inputs
