Neuronal identity and hybrid coding
Recent studies of the olfactory system report that differentiated sensory neurons have an identity evidenced by surface markers. These markers relate to the specificity of the neuron's odorant receptor. During axonal outgrowth the markers co-determine, with which of the second stage neurons synapses are formed. The markers and the resulting connectivity (or network structure) amount to static, ...
متن کاملNeuronal coding and spiking randomness.
Fast information transfer in neuronal systems rests on series of action potentials, the spike trains, conducted along axons. Methods that compare spike trains are crucial for characterizing different neuronal coding schemes. In this paper we review recent results on the notion of spiking randomness, and discuss its properties with respect to the rate and temporal coding schemes. This method is ...
متن کاملBlock structured dynamics and neuronal coding.
When certain control parameters of nervous cell models are varied, complex bifurcation structures develop in which the dynamical behaviors available appear classified in blocks, according to criteria of dynamical likelihood. This block structured dynamics may be a clue to understand how activated neurons encode information by firing spike trains of their action potentials.
متن کاملNeuronal dynamics of predictive coding.
A critical task of the central nervous system is to learn causal relationships between stimuli to anticipate events in the future, such as the position of a moving prey or predator. What are the neuronal phenomena underlying anticipation? In this article, I review recent results in hippocampal electrophysiology that shed light on this issue. It is shown that hippocampal spatial receptive fields...
متن کاملNeuronal coding of prediction errors.
Associative learning enables animals to anticipate the occurrence of important outcomes. Learning occurs when the actual outcome differs from the predicted outcome, resulting in a prediction error. Neurons in several brain structures appear to code prediction errors in relation to rewards, punishments, external stimuli, and behavioral reactions. In one form, dopamine neurons, norepinephrine neu...
