Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones.
Inflammation and increased damage in Alzheimer’s second phase. Following the loss of SST inhibitory neurons, the authors noted that there was an increase in inflammatory cells called microglia ...

SST is a peptide transmitter rather than a receptor, but its expression also maps the preBötC. SST-expressing neurons are breathing essential, but their role is linked to the production of motor output rather than generation of rhythm per se.
[45] [49] By inhibiting PV cells activity, the neuromodulator-sensitive inhibitory cells such as those expressing vasoactive intestinal peptide (VIP) or somatostatin (SST) lift the inhibition of the pyramidal neurons; in other words, the activity of VIP and SST-expressing cells result in the disinhibition of pyramidal neurons.
In applying the SST methodology audio visual material is presented simultaneously with a peripheral, spatially diffuse visual flicker [4] [6] and Fourier techniques are used to extract the amplitude and the phase of the SSVEP at the stimulus frequency. When the stimulus frequency is in the alpha frequency range (8 Hz – 13 Hz), the SSVEP can ...
Sensory stimulation therapy (SST) is an experimental therapy that aims to use neural plasticity mechanisms to aid in the recovery of somatosensory function after stroke or cognitive ageing. Stroke and cognitive ageing are well known sources of cognitive loss, the former by neuronal death , the latter by weakening of neural connections .
These neurons are inhibited by leptin, insulin, and peptide YY and activated by ghrelin. Centrally projecting neurons that contain peptide products of pro-opiomelanocortin (POMC), and cocaine- and amphetamine-regulated transcript (CART). These neurons have widespread projections to many brain areas, including to all nuclei in the hypothalamus.
