These include: a strong and precise (point-to-point) projection from lamina 4B to lamina 2/3A, a reciprocal projection from 2/3A back to 4B, a definite projection from lamina 4B to 5B, as well as a prominent input to lamina 6 from 5B.
The amygdala also receives prominent input from the insula and from the hippocampus and rhinal (olfactory) cortices.
The more superficially a pyramidal cell was located, the more likely it was to also receive prominent excitatory input from LVa.
Thus, the very dense PV immunostaining in area 3b and AI/R also shown in the present study reflects prominent thalamic input from PV-rich VPL and ventral medial geniculate (MGv) neurons, respectively.
For instance, RSA but not RSG receives prominent visual input from both the laterodorsal thalamic nucleus and the visual cortex (Thompson and Robertson 1987; van Groen and Wyss 1992) and is supposed to be an important area for visuospatial information processing based on external sensory information (Pothuizen et al. 2009).
A striking difference between neurons in lower LII/III as compared to those in upper LII/III, was that the latter, in 11 out of 14 cases, received prominent excitatory input from LVa, the main cortical target layer of the paralemniscal pathway.
As we discussed above, the most prominent inputs to the 'canonical' dopamine neurons are from the nucleus accumbens, a part of the ventral striatum, though TS-projecting dopamine neurons received far fewer inputs from the nucleus accumbens.
A prominent contribution from the lay literature is Ricard 2006.
Anatomical studies suggest that superficial layers of PMd receive substantial corticocortical input from frontal association areas39, and connectivity studies in the rodent motor cortex suggest a prominent descending projection from superficial to deep layers40.
There was a lot of input from the different musicians.
