Vesl-1S (186 amino acids, also called Homer) is a protein containing EVH1- and PDZ-like domains whose expression in the hippocampus is regulated during long term potentiation (LTP), one form of synaptic plasticity thought to underlie memory formation (Kato, A., Ozawa, F., Saitoh, Y., Hirai, K., and Inokuchi, K. (1997) FEBS Lett. 412, 183-189; Brakeman, P.(More)
Maintenance of long-term potentiation (LTP) requires de novo gene expression. Here we report the direct isolation, using PCR-differential display, of genes whose expression level was altered after induction of long-lasting LTP in the hippocampus of freely moving awake rats. Differential display using 480 primer combinations revealed 17 cDNA bands that(More)
We have isolated a novel cDNA, vesl, that was induced during convulsive seizure in the rat hippocampus. The vesl gene encodes a protein of 186 amino acids that has significant homology to the EVH1 domain of the VASP/Ena family of proteins implicated in the control of microfilament dynamics. The expression of vesl mRNA was induced in the granule cell layer(More)
OBJECT A brain-machine interface (BMI) offers patients with severe motor disabilities greater independence by controlling external devices such as prosthetic arms. Among the available signal sources for the BMI, electrocorticography (ECoG) provides a clinically feasible signal with long-term stability and low clinical risk. Although ECoG signals have been(More)
Central post-stroke pain (CPSP) is one of the most common types of intractable pain. We reported that repetitive transcranial magnetic stimulation (rTMS) of primary motor cortex relieves pain for patients who were refractory to medical treatment. But the mechanism is unclear. In the present study, we investigated relations between the characteristics of(More)
Electrocorticography of the primary motor cortex (M1) is a promising tool for controlling a brain-computer interface (BCI). Electrocorticograms (ECoG) of the human M1 within the central sulcus (intrasulcal ECoG) have been rarely examined. In order to evaluate the usefulness of intrasulcal ECoG for BCI, we examined patients with subdural electrodes placed(More)
OBJECTIVES Following lesions in somatosensory pathways, deafferentation pain often occurs. Patients report that the pain is qualitatively complex, and its treatment can be difficult. Mirror visual feedback (MVF) treatment can improve deafferentation pain. We sought to classify the qualities of the pain in order to examine whether the potential analgesic(More)
We investigated the retention of lever-pressing behavior in rats rewarded by lateral hypothalamic (LHT) stimulation. Rats with electrodes implanted into the lateral hypothalamus were trained to press a lever to receive LHT stimulation. More than 90% of rats which had self-stimulated for longer than 30 min retained this behavior when tested 1 or 7 days(More)
OBJECTIVE Application of spatially filtered magnetoencephalography (MEG) to investigate changes in the mechanism of cerebral motor control in patients with tumours around the central sulcus. METHODS MEG records were made during a repetitive hand grasping task in six patients with gliomas around the central sulcus and in four control subjects. Power(More)
The authors regret that in our recently published paper entitled, " Frequency-dependent spatiotemporal distribution of cerebral oscillatory changes during silent reading: A magnetoencephalographic group analysis " , the Acknowledgments section was inadvertently omitted. We would like to apologize to all those concerned and amend the original publication(More)
