However it is difficult to separate areas of the brain that are related to the general emotional process from the activity of the brain areas involved in neuronal representations of reward system. The purpose of this study was to determine differences in the brain activity using functional magnetic resonance imaging (fMRI) in male subjects in evaluating an intensity of pleasant images, including erotic, or unpleasant and neutral pictures. When comparing the condition with evaluation of the pleasant erotic images with conditions containing neutral or unpleasant stimuli, a significant activation was observed in the posterior cingulate cortex; the prefrontal cortex and the right globus pallidus. An increased activity of the right anterior central gyrus was observed in the conditions related to evaluation of pleasant and neutral stimuli. Thus, in the process of evaluating the intensity of emotional images of an erotic nature the active brain areas were related not only to neuronal representations of emotions, but also to motivations and control system of emotional arousal, which should be taken into account while using erotic pictures as intensive positive emotional stimuli.</p>","PeriodicalId":49337,"journal":{"name":"Zhurnal Vysshei Nervnoi Deyatelnosti Imeni I P Pavlova","volume":"66 1","pages":"24-35"},"PeriodicalIF":0.3,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34612974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is synthesized as a precursor protein (proBDNF) that undergoes proteolytic cleavage in order to become a mature molecule. It was repeatedly shown that the proBDNF/ mBDNF ratio is determined by concomitant neuronal activity. A growing body of evidence argues that proBDNF has its own biological functions, oftentimes in opposition to functions of the mature molecule. Therefore, the balance of concentrations of proBDNF and mature neurotrophin is an important constituent of in any biological processes in nerve cells.

During preparation for stair descent these velocity fluctuations appeared mainly in autistic adolescents, moreover, autistic children exhibited less velocity fluctuations than children in control group while preparing for stair descent. The kinematics of the movement itself demonstrated significantly less hip abduction in both autistic children and adolescents than in age-matched controls during stair ascent, and less ankle joint plantar extension in autistic adolescents than in healthy adolescents during stair descent.

Oscillation properties were measured using the relative power (RP) indices of theta-, alpha-, beta- and gamma-rhythms. Institutionalized children showed higher RP of alpha rhythm in seven loci (frontal polar, anterior temporal, posterior temporal and left occipital derivations), lower RP of theta rhythm in eight loci (frontal polar, frontal, anterior temporal and posterior temporal derivations).

Since an increase of low-frequency oscillations in the orbitofrontal cortex is observed in aversive states, whereas their decrease in the DMN reflects an activation of this network, which is related to self-referenced processing, our results are consistent with the notion that vulnerability to depression is associated with general negative emotional disposition and excessive focus on the self.</p>","PeriodicalId":49337,"journal":{"name":"Zhurnal Vysshei Nervnoi Deyatelnosti Imeni I P Pavlova","volume":"65 3","pages":"344-51"},"PeriodicalIF":0.3,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33929144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Auditory stimulus: 2000 Hz, 70 dB, 40 ms. Visual stimuli: two weak intensities 0.3 and 1 cd/m2. Sound by itself did not elicit a neuronal response. Factor analysis ANOVA revealed that SOA significantly influence on neuronal responses. Neuronal reaction included responses to increase (on-response) and decrease (off-response) of light intensity. Earliest phase of response (40-100 ms from visual stimuli substitution) is most affected by sound. Neuronal reactions of the every interval of SOA comprised both increase and decrease of discharge in response to addition of a sound. We used a Wilcoxon signed-rank test to show the differences between reactions in response to visual and audio-visual stimuli. Audio-visual on-responses statistically exceeded the responses to visual stimuli at -150, -40 and 0 ms SOA for the all neurons. Two groups of neurons were revealed. The first group (n = 16) showed dependence of on-re- sponses on sound in a wide range of SOA: -150, -40, -20, 0, +20, +50 and +100 ms. Also the first group showed maximum increase of spike number (18-28%) in response to audio-visual stimulation. For the second group of neurons there were no significant SOA for on-responses. We haven't found a significant decrease of audio-visual response compared to a visual response. However, we found the tendency to reduction of audio-visual discharge at intervals SOA -750 and -80 ms (p < 0.07) for the first group and at SOA -500 and +20 ms (p < 0.1) for the second group of neurons. Also we revealed that on-responses are more influenced by sound than off-responses. We have researched the audio-visual interaction in the second phase of neuronal discharges (120-160 ms and later, n = 23). Sound influence on a second phase is weaker than on a first phase. Significant SOA for on-responses: 0 ms; for off-responses: +100 and +150 ms. This study has revealed similarities of audio-visual interaction range for animal and psychophysical researches.
