Temperature-sensitive properties of rat suprachiasmatic nucleus neurons.
The hypothalamic suprachiasmatic nucleus (SCN) contains a heterogeneous population of neurons, some of which are temperature sensitive in their firing rate activity. Neuronal thermosensitivity may provide cues that synchronize the circadian clock. In addition, through synaptic inhibition on nearby cells, thermosensitive neurons may provide temperature compensation to other SCN neurons, enabling...
متن کاملThe firing rate of neurons in the nucleus cuneiformis in response to formalin in male rat
Introduction: Although formalin-induced activity in primary afferent fibers and spinal dorsal horn is well described, the midbrain neural basis underlying each phase of behavior in formalin test has not been clarified. The present study was designed to investigate the nucleus cuneiformis (CnF) neuronal responses during two phases after subcutaneous injection of formalin into the hind paw...

the synaptic circuitry of the SCN is largely unexplored. Most SCN Sprague-Dawley rats were housed under a 12-h light:dark cycle neurons use the neurotransmitter g-aminobutyric acid (GABA), and recordings were made predominantly during the light phase. and anatomic studies indicate many GABAergic synapses and local Coronal slices (150–400 mm) of hypothalamus were cut and mainaxon collaterals; ho...
متن کاملAfterhyperpolarization regulates firing rate in neurons of the suprachiasmatic nucleus.
Cluster I neurons of the suprachiasmatic nucleus (SCN), which are thought to be pacemakers supporting circadian activity, fire spontaneous action potentials that are followed by a monophasic afterhyperpolarization (AHP). Using a brain slice preparation, we have found that the AHP has a shorter duration in cells firing at higher frequency, consistent with circadian modulation of the AHP. The AHP...
متن کاملGABAA-mediated local synaptic pathways connect neurons in the rat suprachiasmatic nucleus.
The suprachiasmatic nucleus (SCN) in mammals functions as the biological clock controlling circadian rhythms, but the synaptic circuitry of the SCN is largely unexplored. Most SCN neurons use the neurotransmitter gamma-aminobutyric acid (GABA), and anatomic studies indicate many GABAergic synapses and local axon collaterals; however, physiological evidence for synaptic communication among SCN n...
