Encoding of visual information by lgn bursts
WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): In the lateral geniculate nucleus (LGN) of the thalamus, visual stimulation produces two distinct types of responses known as tonic and burst. Due to the dynamics of the T-type Ca 2þ channels involved in burst generation, the type of response evoked by a particular stimulus … WebAug 1, 2006 · These results suggest a dynamic role for burst responses during visual processing that may change according to behavioral state.

WebFeb 2, 2006 · Here, we exploit this stability to examine temporal filtering of visual information in LGNd neurons as rabbits alternate between EEG-defined states. Within a single second of shifting from alert to an inattentive state, both peak temporal frequency and bandwidth were sharply reduced, and burst frequency increased dramatically. WebEncoding of visual information by LGN bursts. Thalamic relay cells respond to visual stimuli either in burst mode, as a result of activation of a low-threshold Ca2+ …
WebBursts were originally observed during sleep and were thought to represent a decoupling of the LGN from its retinal input [2,3]. However, recent studies have shown that bursts are interspersed with tonic firing in the LGN of awake animals during visual stimulation [4–6] and that bursts can reliably encode visual information [7,8]. WebJun 13, 2006 · The thalamus is considered the relay station for the brain, shuttling information between sensory neurons and the cerebral cortex. Thalamic neurons in the lateral geniculate nucleus (LGN) respond to visual scenes in two distinct modes: sustained and regular tonic responses and short, rapid bursts.
