Title: Changes of intracerebral activity during stimulation of the chest trigger zone according to the Vojta principle Objective: The aim of this study is to examine whether stimulation of the chest trigger zone according to the Vojta principle results in changes of the brain electrical activity in the primary and secondary motor cortical areas evaluated in the sLORETA program. Methods: Seventeen healthy women aged 20-30 (25 ± 6.4) were involved in the experiment. Registration of the scalp EEG was performed with a special EEG cap. EEG was measured in all individuals with eyes closed in order to reduce ocular artifacts and to reduce visual afferentation. EEG activity was registered for 5 min at rest (PRE CE) prior to the actual reflex locomotion stimulation. Subsequently, the electrical activity was followed for 15 min during chest trigger zone stimulation (VOJTA CE). The experiment was terminated with the registration of the resting EEG recording until 5 min after the reflex locomotion stimulation of the trigger zone (POST CE). The obtained data were then statistically compared in the sLORETA program using a pairwise t-test with logarithmic transformation of the aliasing parameter 0,5 with permutation method using 5000 randomizations at the significance level p ≤ 0,05 with correlation for repeated...

Measuring electrical brain activity during stimulation of trigger zones from concept of Vojta principle
Martínek, Milan ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title: Measuring electrical brain activity during stimulation of trigger zones from concept of Vojta principle Objectives: The aim of this study is to clarify whether there is a change in the electrical brain activity evaluated by the sLORETA program during the stimulation of trigger zones according to the Vojta concept. The source activity during stimulation of trigger zones was scanned from the scalp EEG and compared with the sLORETA program with the source activity measured at rest, before and after the stimulation of the trigger zones. Methods: The research was conducted on 11 healthy adult subjects. The entire research group is consisted of women aged in range 19-32. The data was obtained from the scalp EEG before, during and after stimulation of trigger zones according to Vojta concept. For each proband the measurement of resting EEG with both open and closed eyes (2 x 10 minutes) was first performed, then the measurements were taken during the stimulation of trigger zones with open and closed eyes (2 x 15 minutes). Finally, a resting EEG was measured, alternating open and closed eyes after five minutes (4 x 5 minutes). There was a pause of at least 15 minutes between each stimulation of trigger zones. The order of open and closed eyes during resting EEG and during stimulation of trigger...

Prolonged apnea: monitoring brain activity in freedivers
Skopalová, Pavla ; Pánek, David (advisor) ; Nováková, Tereza (referee)
Title: Prolonged apnea: monitoring brain activity in freedivers Objectives: The aim of this study is to monitor the brain electrical activity during the prolonged apnea in freedivers. Prolonged apnea in the water and prolonged dry apnea were compared to each other and also to a resting state before the apnea, all states with the eyes closed. Brain activity was obtained from the scalp EEG and evaluated using the sLORETA program. Methods: The research was conducted in 11 healthy men at the age of 23 - 51. The data was obtained from the scalp EEG. The record was first taken at a resting state before the apneas with eyes closed, then at maximum prolonged dry apnea with eyes closed and finally at maximum prolonged apnea in the water with eyes closed. The lenghts of the prolonged apneas ranged from 2:15 minutes to 5:30 minutes in idividual probands. There were pauses of at least three minutes between each apnea as by the proband's needs. The compared pair groups were following: prolonged apnea in the water against prolonged dry apnea, prolonged apnea in the water against resting state before the apnea and finally prolonged dry apnea against resting state before the apnea, all with the eyes closed. Selected sections of EEG record without artefacts were processed by sLORETA program. In the statistical...
