The kinetic properties, steady state binding characteristics and autoradiographic distribution of the somatostatin (SRIF) sst2 receptor-selective ligand, [125I]-BIM-23027, have been investigated in the rat central nervous system. Analysis of kinetic, saturation and competition binding data in rat hippocampal membranes was consistent with [125I]-BIM-23207(More)
(1) The kinetic properties of single sodium channels modified by the pyrethroid fenvalerate have been analyzed by patch clamp techniques using the cultured mouse neuroblastoma cells. (2) Fenvalerate drastically prolonged the open time of single sodium channels from the normal value of 5 ms to several hundred milliseconds during a depolarizing pulse. The(More)
Somatostatin is a neuromodulator and neurotransmitter in the central nervous system. Administration of somatostatin to the spinal cord or brain areas involved in nociception has been shown to result in analgesia. Little information is available about the somatostatin receptor types which may be involved in mediating the neuromodulatory and analgesic effects(More)
The distribution and cellular localization of the somatostatin sst2(a) receptor was investigated in selected human brain areas using an anti-peptide antibody raised against a carboxy-terminal portion of the receptor protein. The sst2(a) receptor was found to be present on neurones and processes in the deep layers of the cerebral cortex, in the subicular(More)
i ABSTRACT This study explores the psychophysical and neural processes associated with the perception of sounds as either pleasant or aversive. The underlying psychophysical theory is based on auditory scene analysis, the process through which listeners parse auditory signals into individual acoustic sources. The first experiment tests and confirms that a(More)
A post-tetanic hyperpolarization (p.t.h.) that is quantitatively identical to that evoked by a train of action potentials in stretch receptor neurones of crayfish Procambarus clarki and Pacifastacus leniculus is evoked when the normal Na+ influx is blocked with tetrodotoxin (TTX) and a train of depolarizing pulses is used to simulate a train of action(More)
