Development of neuron–neuron synapses
Current Opinion in Neurobiology, 2000Our understanding of neuronal synapse development has advanced in recent years. The development of glycinergic synapses appears to depend on gephyrin and glycine receptor activity. Molecular characterization of the structure and development of glutamatergic synapses is in progress, but the underlying mechanisms remain unclear.

Neuronal IFN-γ in tuberomammillary neurones
NeuroReport, 1994Neuronal interferon-gamma (N-IFN-gamma), recently isolated from the nervous system, has a molecular weight distinct from that of lymphocyte-derived IFN-gamma, but crossreacts immunologically and shares certain bioactivities with this cytokine. In the rat brain N-IFN-gamma-immunoreactive perikarya were concentrated in the hypothalamic tuberomammillary ...

Dopaminergic neurons of the midbrain are the main source of dopamine (DA) in the mammalian central nervous system. Their loss is associated with one of the most prominent human neurological disorders, Parkinson's disease (PD). Dopaminergic neurons are found in a 'harsh' region of the brain, the substantia nigra pars compacta, which is DA-rich and ...

This paper examines the concept of neuronal assembly as it has appeared in selected portions of the literature. The context is experimental access to real neuronal assemblies in working brains, as made possible by recent technological progress. One current measure of assembly organization is based on correlation of firing among neurons; recent ...

The controlled navigation of the axonal growth cone of a neuron toward the dendrite of its synaptic partner neuron is the fundamental process in forming neuronal circuitry. While a number of technologies have been pursued for axonal guidance over the past decades, they are either invasive or not controllable with high spatial and temporal resolution ...

Science, 1959
An electronic model is described for simulating many of the gross operational functions which are believed to hold for living nerve cells. Synaptic growth is not included. Despite difficulties in drawing very rigorous analogies between the biological cell and its model, a sufficient number of rough similarities exist to make systemic experimentation ...

Biological tools that are unleashed in malignancies are employed in a controlled manner during neuronal development. By default, early embryonic cells would become neuronal stem cells, a path that is blocked by specific signaling pathways. The future nervous system only develops where this blockade is inhibited by inductive signals from the 'organizer'.

One tends to think of the nervous system in terms of chains of excitatory signals that tell neurons to fire. The signals that say "Don't fire" also have a major role. Inhibitory signals damp overall neural activity and also fine-tune the responses of particular circuits. The primary carrier of these signals is the inhibitory transmitter known as GABA.
