The information superflyway
Article Abstract:
The processing of information in the visual system of blowflies involves information reception by the photoreceptors and large monopolar cells (LMCs), and its transmission by neural dendrites. The LMCs are non-spiking neurons and their rate of information capture is very high. The dendrites of neurons in the lobular plate increase the transmission of information using a fast sodium current. The processing of information ensures that the response to a stimulus uses the minimum number of neurons possible.

A taste of things to come
Article Abstract:
R. Margolskee and colleagues have thrown new light on vertebrate taste receptor cells by providing some possible mechanisms for the complex chemotransduction of taste. Visual transducin is expressed in some rat and bovine taste-receptor cells and may be linked to bitter taste transduction. A cyclic-nucleotide-suppressible conductance has also been found in frog taste-receptor neurons, a novelty since previously cyclic nucleotides were not known to suppress or inactivate ion channels directly.

Multiple spike-initiation zones in single neurons revealed by voltage-sensitive dyes
Article Abstract:
Optical recordings from different neurons show that multiple spike trigger zones exist in separate axonal branches of a neuron and this indicates that neurons may be functionally subdivided. The membrane excitability is different in different regions of the same neuron. Spike initiation, and pattern and nature of signal processing is complex and difficult to predict. A study records membrane potential changes using voltage-sensitive dyes to understand neuronal processes.
