Photic and non-photic inputs are reported to affect clock gene expressions and behavioral
activities in the SCN. However, it is not known whether dopaminergic input mediates these …

Because the rapid induction of Period (Per) genes is associated with the photic entrainment
of the biological clock, we examined whether N-methyl-d-aspartate (NMDA) receptors were …

A role for dopamine (DA) in the regulation of clock genes in the mammalian brain is
suggested by evidence that manipulations of DA receptors can alter the expression of some …

The suprachiasmatic nucleus (SCN) of the hypothalamus receives dense serotonergic
projections from the raphe nuclei and this input has been implicated in the modulation of …

The suprachiasmatic nucleus (SCN) of the hypothalamus is a nucleus that regulates
circadian rhythms through the cyclic expression of clock genes. It has been suggested that …

Abstract Rationale±3, 4-Methylenedioxymethamphetamine (MDMA,'ecstasy') is a
psychoactive drug that has marked effects on the serotonergic system. Serotonergic …

Using a transgenic mice model (ie “clock” knockouts), clock transcription factors have been
suggested as critical regulators of dopaminergic behaviors induced by drugs of abuse …

Oscillations of gene expression and physiological activity in suprachiasmatic nucleus (SCN)
neurons result from autoregulatory feedback loops of circadian clock gene transcription …

Behavioral rhythms induced by methamphetamine (MAP) treatment in rats are independent
of the circadian pacemaker in the suprachiasmatic nucleus (SCN). To know the site and …

In mammals, the environmental light/dark cycle strongly synchronizes the circadian clock
within the suprachiasmatic nuclei (SCN) to 24 hr. It is well known that not only photic but also …
