Encoding of Visual Information by LGN Bursts. J. Neurophysiol. 81: 2558-2569, 1999.
Encoding 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+ conductance, or in tonic
mode, when this conductance is inactive. We investigated the role of
these two response modes for the encoding of the time course of dynamic
visual stimuli, based on extracellular recordings of 35 relay cells
from the lateral geniculate nucleus of anesthetized cats. We presented
a spatially optimized visual stimulus whose contrast fluctuated
randomly in time with frequencies of up to 32 Hz. We estimated the
visual information in the neural responses using a linear stimulus
reconstruction method. Both burst and tonic spikes carried information
about stimulus contrast, exceeding one bit per action potential for the
highest variance stimuli. The "meaning" of an action potential,
i.e., the optimal estimate of the stimulus at times preceding a spike,
was similar for burst and tonic spikes. In within-trial comparisons,
tonic spikes carried about twice as much information per action
potential as bursts, but bursts as unitary events encoded about three
times more information per event than tonic spikes. The coding
efficiency of a neuron for a particular stimulus is defined as the
fraction of the neural coding capacity that carries stimulus
information. Based on a lower bound estimate of coding efficiency,
bursts had ~1.5-fold higher efficiency than tonic spikes, or 3-fold
if bursts were considered unitary events. Our main conclusion is that
both bursts and tonic spikes encode stimulus information efficiently, which rules out the hypothesis that bursts are nonvisual responses.
