Coordinate high-frequency pattern of stimulation and calcium levels control the induction of LTP in striatal cholinergic interneurons.
Current evidence appoints a central role to cholinergic interneurons in modulating striatal function. Recently, a long-term potentiation (LTP) of synaptic transmission has been reported to occur in these neurons. The relationship between the pattern of cortico/thalamostriatal fibers stimulation, the consequent changes in the intracellular calcium concentration ([Ca2+]i), and the induction of sy...
متن کاملBurst Stimulation
The brain is a complex adaptive system, processing information from the internal and external environment. Information is transmitted within the nervous system in at least 2 separate firing patterns, tonic and burst firing. Burst firing consists of closely spaced spikes at high frequency (eg 500 Hz) followed by quiescent periods. It has been proposed that burst firing is a signal detector, a ki...
متن کاملCalcium ion influx during mitogenic stimulation of lymphocytes.
The uptake of free calcium ion (Ca2+) in PHA- or A23187-stimulated lymphocytes was measured using 45CaCl2 and 3H-water. Augmentation of Ca2+ uptake by both mitogens was observed, but the enhanced uptake occurred transiently, sometime within 30 min of the stimulation. The total amount of calcium in quiescent lymphocytes as determined by atomic absorption spectroscopy was about 2.9 X 10(-15) g/ce...
متن کاملEffects of High-Frequency Repetitive Transcranial Magnetic Stimulation on Motor Functions in Patients with Subcortical Stroke
Background: Motor function impairment occurs in approximately two-thirds of patients with subcortical stroke. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique for modulating cortical excitability. Objectives: The present study was designed for assessing the efficacy of high-frequency rTMS (5 Hz) on ipsilesional primary motor cortex in patients with subcortical stro...
متن کاملA Comparative Study of the Impact of Theta-Burst and High-Frequency Stimulation on Memory Performance
The transformation of the information stored in the working memory into the system of long-term memory depends on the physiological mechanism, long-term potential (LTP). In a large number of experimental studies, theta-burst stimulation (TBS) and high-frequency stimulation (HFS) are LTP induction protocols. However, they have not been adapted to the model related to memory. In this paper, the i...
