Notably, interconnected forebrain circuitry involved in the perception and production of learned vocalizations has been discovered in all three avian vocal learning groups [ 16– 24].
In terms of text architecture and hodological relationships, the structure of this chapter corresponds to an ascending Jacksonian-type hierarchy from spinal cord through to cortex, since the aim was to convey a dynamic perspective, both in terms of the physiology of individual neurons and at the level of cortical and sub-cortical networks and their interconnecting circuitry.
H2O2 is likely to be the primary signal closest to the original stimulus (chilling) providing the initial trigger for a cascade of molecular processes leading to an intricately interconnected gene expression circuitry [ 101, 102].
The network involved 70 nodes among which the GATA transcription factor family members (GATA1, GATA2, GATA3, and GATA6) form interconnected autoregulatory and feedforward circuitry (in yellow), suggesting that GATA TFs are active in transcriptional regulation in human ES cells.
Network analysis of the 353 core-bound genes using IPA (Ingenuity Systems, http://www.ingenuity.com/) shows that the top network involves 32 genes among which the three core TFs, NANOG, OCT4, and SOX2, were hub nodes in the network, and formed interconnected autoregulatory and feedforward circuitry.
In particular, high blood pressure can cause changes to white matter and neuronal circuitry interconnecting the frontal and subcortical areas, regions of the brain associated with decision making and mood.
These regions appear to be interconnected in an ascending spiral so that information relating to reward/aversion and motor function is likely mixed in this circuitry [83].
Mathematics can help manufacturers optimise the way solar cells are interconnected so that the areas in shade, or not at 90° to the sun (which therefore act as resistors in the circuitry), have minimum impact on the power output of the solar panel.
