medial geniculate nucleus (audition)
tonically inhibited by the internal globus pallidus (see basal ganglia#circuitry)
mamillo-thalamic tract from mammillary bodies into nucleus anterior -> anterior cingulate cortex (part of the Papez circuit)
various important thalamocortical loops/circuitry???
isothalamus
thalamocortical neurons (aka principal(???))
no initial axon collaterals
imlies that one emitting thalamocortical neuron does not send information to its neighbor
send long-range glutamatergic projections to the cerebral cortex
microneurons
short and thin dendrites
GABA-ergic
apparently more corticothalamic than thalmocortical axons
two kinds of corticothalamic endings
classical projection - from layer 6 of cortex
thin, long, straight trajectory
glutamatergic synapses
Rockland type II
emanates from large pyramidal cells
synapses are close to the soma of the thalamic neuron
often forming center of glomerular complexes
Gk 'bedroom chamber'
nucleus reticulus = perithalamus???
in/outside thalamus???
