act(p(HGNC:CHRNA7)) increases bp(GO:"action potential initiation") View Subject | View Object

It is noteworthy that, via such mechanisms, alpha7 nAChR activation could trigger rebound burst firing in SLM interneurons even in the absence of excitation (256). Burst firing in SLM interneurons suppresses spikes in pyramidal neurons evoked by stimulation of Schaffer collaterals (134), and, thereby allows selective activation of the pyramidal cells via the perforant pathway.

It is possible that the presence of CHT1 in the membrane of synaptic vesicles and the consequent increase in CHT1 relocation to the plasma membrane following neuronal depolarization could explain why an increase in neuronal firing promotes increased choline reuptake and, thus, ACh synthesis PubMed:26813123

a(MESH:Glutamates) increases bp(GO:"action potential initiation") View Subject | View Object

By acting on the α7 receptors in glutamate terminals, acutely administrated nicotine stimu- lates the release of glutamate, which facilitates the burst fir- ing of VTA DA neurons and eventually leads to LTP,and increases the firing rate of the GABAergic neurons of the rostromedial tegmental nucleus PubMed:28901280

nicotine modulates the shift towards burst firing and increases DA release in the NAc PubMed:28901280

nAChRs are expressed also at the somatodendritic postsynaptic site, where they regulate neuron depolarisation, firing and long- term potentiation [9]. Moreover these receptors are also in- volved in proliferation, differentiation and migration of neu- ral progenitors PubMed:28901280
