CMOS programmable asynchronous neighborhood mechanism for WTM kohonen neural network

A new programmable neighborhood mechanism for the Winner Takes Most (WTM) self-organizing Kohonen map has been proposed in this paper. Described circuit is an asynchronous solution, which does not require the controlling clock generator. The winning neuron ...

C/EBPbeta couples dopamine signalling to substance P precursor gene expression in striatal neurones

Pierre Magistretti, Jean-René Cardinaux

Dopamine-induced changes in striatal gene expression are thought to play an important role in drug addiction and compulsive behaviour. In this study we report that dopamine induces the expression of the transcription factor CCAAT/Enhancer Binding Protein b ...

Modelling pesticides residues

Raphael Charles

This work is a contribution to the development of a specific method to assess the presence of residues in agricultural commodities. The following objectives are formulated: to identify and describe main processes in environment — plant exchanges, to build ...

Cellular perspectives on the glutamate-monoamine interactions in limbic lobe structures and their relevance for some psychiatric disorders

Pierre Magistretti

Dopaminergic, serotonergic and noradrenergic nuclei form the trimonoamine modulating system (TMMS). This system modulates emotional/motivational activities mediated by the limbic circuitry, where glutamate is the major excitatory neurotransmitter. Two main ...

Ordonnancement dynamique d'une machine flexible Formulation en processus de Bandits-manchots

Max-Olivier Hongler, Fabrice Dusonchet

We explore the scheduling rules and the hedging levels that can be obtained by using a Restless Bandit Problem formulation of a make-to-stock production. The underlying dynamics are markov chain in continuous lime and the associate reward are piecewise lin ...

Spontaneous recovery of deficits in spatial memory and cholinergic potentiation of NMDA in CA1 neurons during chronic lithium treatment

Henry Markram

The therapeutic action of lithium in affective disorders is still unclear. One effect of lithium is to deplete membrane inositol and consequently to exhaust the phosphoinositide (PI) pathway. Under chronic lithium treatment, rats showed persistent performa ...

Dopaminergic supersensitivity induced by denervation and chronic receptor blockade is additive

Pierre Magistretti

A persistent, severe reduction of synaptic transmission has been shown to enhance the responsiveness of postsynaptic tissue to the deficient neurotransmitter—a phenomenon called postjunctional supersensitivity. Regardless of whether supersensitivity is ind ...
