However, such increase in excitability may be (at least partly) counteracted by the resulting boost in interneurons firing which triggers synaptic release of GABA, overall increasing extracellular levels of this species and promoting, in turn, neural inhibition.
In turn, neural crest-derived Schwann cells migrate along the axons which they eventually myelinate (Gilmour et al., 2002; Lyons et al., 2005).
There is evidence such cells can also turn into neural cells, blood vessels and bone- and insulin-making cells.
In fiction I can turn the neural implant into a silvery vial of nano-particles that you swallow, in and which then self-assemble into circuits in your brain.
(Today, this argument is generally associated with Popper and Eccles, 1977. It is an old argument, however, and clear statements of it were offered by James (1879) and by Romanes in 1882 (see Romanes, 1896).) According to the same biology that embraces natural selection, however, behavior has muscular causes, which in turn have neural causes.
The stem cells don't last forever, and they don't turn into neural cells as scientists first suspected more than a decade ago, Steinberg said.
Thus, Wnt activity caudalizes prospective forebrain cells and promotes BMP signaling, which in turn induces neural crest cells.
Since amygdala is typically involved in processes involving emotion and arousal regulation [43], the higher amygdala to PFC influence may suggest that the exposed adolescents may have a higher baseline arousal level, which in turn affects neural activity in the executive control network [15].
These symptoms indicate the presence of a vascular restriction, which in turn affects neural function.
Now, Zhu et al. have shown that a transcription factor called Pou3f1 triggers stem cells within a region of the ectoderm to turn into neural progenitor cells, thereby generating the neuroectoderm.
Scientists found, almost serendipitously, that when treated with chemicals called retinoids, some of the cells turned into neural cells.
