Bursting firing
WebNov 2, 2024 · The BAC-firing coincidence detection mechanism [19,20] employs burst firing to associate the activity of several presynaptic neurons impinging on different parts of the dendrite. Bursting also gives rise to a substantial increase in vesicle release probability at the synapse [ 21 ] and promotes switching between various states during sleep [ 22 ].
