چکیده

Synaptic depression at conventional synapses is usually caused by strong or prolonged stimuli, like tetanic bursts of afferent fiber discharge at high frequencies. In this issue of Neuron, Dunn and Rieke report that, in the retina, even the weakest stimuli, single photons, can lead to synaptic depression at ribbon-type synapses and adaptation of neuronal output to ambient light levels.

Dynamics of Synaptic Transmission and Neural Code

In the light of the latest results concerning the synaptic paired pulse depression, facilitation [Thomson et al., 1993 a,b,c], its effects on long term potentiation (LTP) and depression (LTD) [Markram et al., 1996], and spike frequency adaptation, the question how the neurons communicate and what are meaningful signals in the neural information processing has to be reconsidered. Modeling these ...

Input-specific adaptation in complex cells through synaptic depression

A number of experiments have reported that neurons in primary visual cortex can adapt in a stimulus-dependent manner. Synaptic depression is a plausible mechanism for this type of adaptation because its synapse speci"city allows modi"cation of particular inputs while allowing others to remain una!ected. Furthermore, a form of synaptic depression measured in slice experiments sets in and recover...

Population Models of Temporal Differentiation

Temporal derivatives are computed by a wide variety of neural circuits, but the problem of performing this computation accurately has received little theoretical study. Here we systematically compare the performance of diverse networks that calculate derivatives using cell-intrinsic adaptation and synaptic depression dynamics, feedforward network dynamics, and recurrent network dynamics. Exampl...

Single-Photon Absorptions Evoke Synaptic Depression in the Retina to Extend the Operational Range of Rod Vision

Adaptation or gain control allows sensory neurons to encode diverse stimuli using a limited range of output signals. Rod vision exemplifies a general challenge facing adaptational mechanisms-balancing the benefits of averaging to create a reliable signal for adaptation with the need to adapt rapidly and locally. The synapse between rod bipolar and AII amacrine cells dominates adaptation at low ...

Detection of Ultraweak Photon Emission (UPE) from Cells as a Tool for Pathological Studies

Objective: It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...
