Farklı Isı Düzeylerinin Dokunsal Alışmaya Herhangi Bir Etkisi Var mı? Ön EEG Sonuçları

Habituation is a basic process of learning which can be observed when the sensory stimulus

repeated. The habituation mechanism can also be thought as filtering the meaningful

information from the real world. In the literature, many studies were aimed to establish visual

and auditory stimulation effects on the habituation mechanism. In somatosensory domain

generally repeated electrical, vibrational, and heat stimulus was used. The current study aimed

to investigate the effects of different inter-stimulus intervals on the habituation process by

non-painful tactile stimulations. 7 right-handed volunteers (4F; 23 ± 5.7 age) who have no

previous neurological, psychological and chronic diseases, participated in the study. The

somatosensory evoked potential (SEP) paradigm was used. 40 stimuli applied in both ISI2

and ISI16 session. Brain responses were recorded via electroencephalography (EEG). The

non-painful tactile stimuli (~ 140 kPa air pressure) stimuli delivered to the pulp of right-hand

index finger via the pneumatic stimulation unit. The off-line EEG analyzed by Scan 4.5

(NeuroScan Inc., USA). SPSS (v24) was employed for the statistical analysis. Accordingly, to

the analysis, there is a significant increase in amplitudes and durations of brain responses

were observed as ISIs are increased. These preliminary results can shed the light the basic

habituation process on the somatosensory domain.
