Previous studies have proven that a dipole source analysis of the auditory evoked field is capable providing evidence tonotopic organization human cortex. To explore nature estimated dipoles in greater detail, single subject was extensively studied, and sources were registered three-dimensional reconstruction cortical surface derived from magnetic resonance images. The stimuli 500-ms tone bursts with frequencies 250, 500, 1,000, 2,000 Hz (mean intensity 60 dB SL). total number presented per...
According to the place principles of classical hearing theory, physical entity frequency is encoded in auditory periphery as information (tonotopic representation), which decoded more central parts system form subjective pitch. However, this relation true only for pure-tone signals (spectral pitch); it can be quite different case complex stimuli (virtual pitch), thus requiring a multistage process pitch formation. Neuromagnetic measurements showed that tonotopic organization primary cortex...
Both auditory-evoked magnetic fields (AEMF) and potentials (AEP) mainly consist of three peaks with latencies about 50, 100 160 ms. Comparison responses to ipsilateral, contralateral binaural stimulation yields no significant amplitude or latency differences the AEP whereas simultaneously recorded AEMF exhibit a 10 ms shorter an approximately 38% greater for versus ipsilateral stimulation. This fact can be due in strength, location (especially depth) direction dipole source, decision cannot...
Abstract Movement‐related neuromagnetic fields from eight healthy human subjects were investigated in a Bereitschaftspotential paradigm. The three conditions studied right‐sided mouth, index finger and foot movement. field patterns corresponding to the motor movement‐evoked I analysed using moving dipole model. For both components somatotopic organization was found: estimated locations for mouth more lateral those medial than positions With regard possible clinical applications, e.g....
An Auditory Ambiguity Test (AAT) was taken twice by nonmusicians, musical amateurs, and professional musicians.The AAT comprised different tone pairs, presented in both within-pair orders, which overtone spectra rising pitch were associated with missing fundamental frequencies (F0) falling pitch, vice versa.The F0 interval ranged from 2 to 9 semitones.The participants instructed decide whether the perceived went up or down; no information provided on ambiguity of stimuli.The majority...
Impaired speech perception is one of the major sequelae aging. In addition to peripheral hearing loss, central deficits auditory processing are supposed contribute deterioration in older individuals. To test hypothesis that temporal compromised aging, evoked magnetic fields were recorded during stimulation with sequences 4 rapidly recurring sounds 28 healthy individuals aged 20 - 78 years.The decrement N1m amplitude rapid was not significantly different between and younger adults. The...
We aimed to find out what extent functional representations of different fingers the two hands overlap at human primary and secondary somatosensory cortices SI SII. Somatosensory evoked fields (SEFs) were recorded with a 306-channel neuromagnetometer from 8 subjects. Tactile stimuli, produced by diaphragms driven compressed air, delivered fingertips in three conditions. First, right index finger was stimulated once every 2 s. Then other stimuli interspersed, sessions, right- or left-hand...
