Abstract Interventional paired associative stimulation (IPAS) to the contralateral peripheral nerve and cerebral cortex can enhance primary motor (M1) excitability with two synchronously arriving inputs. This study investigated whether dopamine contributed long‐term potentiation–like effect in M1 Parkinson's disease (PD) patients. Eighteen right‐handed PD patients 11 age‐matched healthy volunteers were studied. All studied after 12 hours off medication levodopa replacement (PD‐off). Ten also...
Summary: Purpose: To investigate underlying mechanisms and adequate parameters for electric cortical stimulation to inhibit epileptic focus in humans. Methods: A patient with intractable partial epilepsy had subdural electrodes implanted preoperative evaluation. Cortical functional mapping was performed by using 50‐Hz alternating square pulse of 0.3‐ms duration, 1 7 mA, within 5 s. Spike frequency electrocorticogram (ECoG) power spectra were compared before after the when distant area...
We investigated the role of cerebral cortex, particularly face/tongue area primary sensorimotor (SMI) cortex (face/tongue) and supplementary motor (SMA), in volitional swallowing by recording movement-related cortical potentials (MRCPs). MRCPs with tongue protrusion were recorded from scalp electrodes eight normal right-handed subjects implanted subdural six epilepsy patients. The experiment EEG revealed that premovement Bereitschaftspotentials (BP) activity for was largest at vertex...
Objectives: This study aimed to investigate the differences between source localization of P300 event-related potential (ERP) component among healthy and mild brain injury (MBI) patient population using standardized low-resolution electromagnetic tomography (sLORETA). Methods: Thirty-eight participants were divided into control (n = 19) MBI groups. Control normal, people, with assigned two groups: 1st Test (7 days after a road traffic accident (RTA)) 2nd (2–6 months RTA same group). The...
A unique feature of Japanese language is that its written sentences consist both morphograms (kanji) and syllabograms (kana). Despite extensive research by PET, functional MRI magnetoencephalography, the issues difference (or similarities) between processing kanji kana, word reading object/picture naming have not been resolved as yet. This study investigated function posterior basal temporal area in dominant hemisphere auditory visual processing, with special emphasis on semantic...
To test whether low-frequency repetitive transcranial magnetic stimulation (rTMS) of sensorimotor cortex (SM1) has prolonged effects on somatosensory function, eight subjects were given 900 TMS pulses over the left hand SM1 (0.9Hz, 90% resting motor threshold) or at sites 3 cm anterior posterior to it. Tactile threshold right was increased for a short duration after rTMS SM1, but two-point discrimination and median nerve SEPs unaffected any sites.
Summary: Purpose: Atonic seizures are commonly seen in patients with generalized epilepsy but only infrequently partial epilepsy. Clinically atonic as a have not been studied detail video/EEG monitoring. Here we describe the clinical and physiologic characteristics of due to discuss underlying mechanism. Methods: Two manifesting seizures, one frontal lobe (FLE) other parietal (PLE), were reported. The long‐term monitoring, magnetic resonance imaging (MRI), interictal...
In biometric system, the fingerprint recognition has been researched for long period of time and it shown most promising future in real world application. However, because complex distortions among different impression same finger life, is still a challenging problem. Matching two fingerprints can be unsuccessful due to various reasons also depends upon method that being used matching. Electronic Voting Machine (EVM) simple electronic device record votes place ballot papers boxes which were...
Abstract Neocortical neuronal circuits are refined by experience during the critical period of early postnatal life. The shift ocular dominance in visual cortex following monocular deprivation has been intensively studied to unravel mechanisms underlying experience‐dependent modification. Synaptic plasticity is considered be involved this process. We previously showed layer 2/3 pyramidal neurons rat that low‐frequency stimulation‐induced long‐term potentiation (LTP) at excitatory synapses,...
The localization of active sources inside the brain is termed as source localization.
