✅ Overview of the procedure of #Neurofeedback

🔹 Neurofeedback begins with observation of neural activity. Electrophysiological methods to detect such activity include electroencephalography (EEG), magnetoencephalography (MEG) and invasive electrocorticography (ECoG), and haemodynamic imaging methods for detecting neural activity include functional MRI (fMRI) and functional near-infrared spectroscopy (fNIRS). The grids on canonical neural tissues provide a qualitative reference for the relative spatial resolutions of the various imaging technologies. Sample signals that are extracted from both types of these sensor channels provide a qualitative representation of the difference in temporal resolution. Electrophysiological and haemodynamic signals can be processed in similar ways. Univariate approaches extract a signal from a single channel or region of interest, for example, an evoked potential. Calculation of coherence or connectivity between two channels as a measure of functional connectivity is another common feedback method. Features from a set of sensors, such as the power at a frequency window or the level of activation, can be classified as multivariate patterns of activity (MVPAs). The calculated signal is then presented to the individual via visual, auditory, haptic or electrical stimulation feedback, allowing the user to alter neural function and complete the loop with neural processing of feedback. The advantages and disadvantages of these modalities, as well as how their signals are processed for neurofeedback, are discussed in BOX 1. FFT, fast Fourier transformation.

🔵 20 مقاله برتر نوروساینس در سال 2016 از نگاه مخاطبین پایگاه neurosciencenews
✅ http://neurosciencenews.com/top-2016-neuroscience-articles-5842/
1⃣ قسمت اول

@Farmed
✅ 1- افسردگی تمامی بدن را تحت تاثیر قرار می‌دهد:
The research team discovered depression was linked to an increase in oxidative stress and decrease in antioxidant substances. Additionally, after receiving treatment, both levels of malondialdehyde, a biomarker of oxidative stress, and antioxidant substances returned to normal.

@Farmed
✅ 2- شناسایی یک ویروس و دو باکتری خاص که منجر به آلزایمر می‌شوند:
The international research team linked the development of Alzheimer’s disease to a specific virus and two types of bacteria, providing evidence that the neurodegenerative disease had a dormant microbial component. They also found that the dormant microbes could become active with iron dysregulation.

@Farmed
✅ 3- شناسایی بیومارکر خستگی مزمن در باکتری‌های روده:
Researchers reported they had identified biomarkers for chronic fatigue syndrome in both inflammatory microbial agents in the blood and gut bacteria.
The findings provide new evidence against the long standing concept that CFS is merely a psychological disorder, by identifying biological biomarkers for the disease.

@Farmed
✅ 4- مصرف ماری‌جوانا با کاهش آزادشدن دوپامین در ارتباط است:
Researchers discovered that those who used marijuana heavily expressed lower dopamine release in the striatum, an area of the brain associated with working memory and attention.
This was a ground breaking finding as previous studies had linked similar alterations in dopamine release to heavier drugs, such as cocaine and heroin.

@Farmed
✅ 5- تاثیر منفی اینترنت بر روی حافظه انسان:
Researchers from UC Santa Cruz and the University of Illinois report that our ever increasing reliance on the internet and our ease of access to new information is affecting our ability to learn and recall facts from memory, as well as impeding our ability to solve problems.
The researchers also found that our ‘cognitive offloading’, our reliance on technology as a memory aid, increased after each time it was used.

@Farmed
✅ 6- شناسایی 4 نوع شخصیت پایه‌ای در انسان:
Researchers from the Carlos III University of Madrid released a new paper which claimed that 90 percent of the population can be classified into one of four personality types. The four basic personality types the researchers identified were: trusting, envious, pessimistic and optimistic, with most people falling into the envious personality type (30% of the population).
The researchers believe the findings are not only important for the field of social psychology, but also for the future development of robots to make them more ‘humanized’.

@Farmed
✅ 7- ضربات سر در فوتبال باعث ایجاد تغییرات در مغز می‌گردد:
Researchers found that, after playing for just one season, football players showed significant changes in both white and gray matter that was associated with head trauma.

2⃣ قسمت دوم

@Farmed
✅ 8- نحوه تاثیر LSD بر روی مغز:
Researchers from Imperial College London used neuroimaging technology to reveal what happens in the human brain when people experience visual hallucinations after taking LSD.
The findings not only help to identify how LSD can help people overcome psychiatric conditions, such as depression, they also could help to shed new light on current concepts of consciousness, the researchers believe.

@Farmed
✅ 9- خوردن ماهی در زمان بارداری باعث بهبود رشد مغز نوزاد می‌شود:
Researchers from Tohoku University’s School of Medicine advised pregnant women to up their fish consumption as the dietary lipids from fish are essential for normal brain formation in the unborn child.
The study also reveals that fish oils are important for brain function and development as we age.

@Farmed
✅ 10- مکمل‌های غذایی می‌توانند باعث پیشگیری و روند معکوس پیری مغز شوند:
A new study reported that a complex dietary supplement, which contains over 30 vitamins and minerals, appears to show amazing anti-aging properties.
Additionally, this new supplement may prevent, and even reverse, brain cell loss. This, researchers believe, could have major implications for the prevention of neurodegenerative diseases, such as Alzheimer’s and ALS.

@Farmed
✅ 11- دستکاری نورون‌های خاص به پاک شدن خاطرات بد و تقویت خاطرات خوب کمک می‌کند:
Researchers at Stony Brook reported they had discovered a possible method for ‘tuning’ the strength of a memory by manipulating acetylcholine levels with optogenetics. Not only were the researchers able to ‘tune down’ negative memories, they were also able to enhance positive memories.
The findings could be used to develop new treatment options for both neurodegenerative diseases and PTSD.

@Farmed
✅ 12- گونه‌های خاصی از باکتری روده می‌توانند باعث روند معکوس رفتارهای اجتماعی مرتبط با اتیسم شود:
Researchers reported that a strain of Lactobacillus reuteri found in human breast milk has the potential to reverse problematic social behaviors in mouse models of Autism.
The researchers suggested that the absence of this specific species of bacteria could be a cause of the social deficits associated with ASD.
They also reported that introducing the bacteria back into the gut could, potentially, help to reverse some social and behavioral problems in people on the Autism spectrum.

@Farmed
✅ 13- ریتم تنفس حافظه و ترس را تحت تاثیر قرار می‌دهد:
Researchers have been able to link breathing rhythm to emotional judgement and enhanced memory recall.
There is a ‘dramatic difference’ in neural activity in both the hippocampus and amygdala depending on whether you are inhaling or exhaling, the researchers report. This can affect how you perceive stimuli and your ability to recall memories.

✅ 14- چگونگی تاثیر LSD بر روی پردازش کلامی:
Researchers reported that, when people under the influence of LSD were asked to name specific objects, their reaction times did not change, but they were more likely to mistakenly call objects by different names. For example, when presented with an image of a car, people who had taken LSD would instead name the stimuli as a ‘bus’ or other vehicle.
Based on their findings, the researchers believe that LSD could allow ‘quicker access to far away concepts stored in the brain’ (Neiloufar Family) and could help in the treatment of psychiatric illnesses.

3⃣ قسمت سوم

@Farmed
✅ 15- منسوخ شدن بروکا و ورنیکه و نیاز به بازبینی نوروبیولوژی پردازش کلامی:
A new paper published by the BPS argued that the ‘Classic Model’ of language function in the brain is obsolete and the continued use could be hampering progress when it comes to researching language production. The researchers call for a new approach that considers how much of language function is overlaid on the cognitive system.

@Farmed
✅ 16- بخشی از مغز افراد افسرده با رخ دادن اتفاقات منفی برعکس عمل می‌کند:
Researchers from University College London discovered people with depression had hyperactive habenula function. Surprisingly, when faced with an adverse event, habenula activity decreased in depressed people. The findings suggest that this brain area functions in a much different way in people with this psychiatric condition.

@Farmed
✅ 17- نحوه ارتباط نورون‌ها با یکدیگر:
While not so much of a breaking news story, one of our most popular articles of the year provided a comprehensive breakdown of the process of neurotransmission.

@Farmed
✅ 18- هوش انسان از داشتن یک الگوریتم پایه در مغز سرچشمه می‌گیرد:
A groundbreaking piece of research that demonstrated our complex brain computations and intelligence are reliant upon a fairly basic algorithm. However, the researcher noted exceptions to the math rule in areas such as the reward system.

@Farmed
✅ 19- باورهای مذهبی مدارهای نورونی پاداش را همانند مواد مخدر، رابطه جنسی و موسیقی فعال می‌کنند:
A new neurotheology study looked at the neural networks that are involved in feelings of spirituality.
Through neuroimaging technology, researchers identified activation in the nucleus accumbens, an area of the brain associated with reward, when powerful spiritual feelings are encountered. Interestingly, similar brain activation occurs when people are exposed to pleasurable stimuli such as sex, drugs, music and gambling.

@Farmed
✅ 20- نقش هیپوکامپ در برنامه‌ریزی و فکر‌ کردن به آینده:
Researchers from Boston University Medical Center reported a new role for the hippocampus. While the hippocampus is well known for its role in memory, researchers discovered that this area of the brain may also be critical for imagination and future planning.

✅📑 مقاله مروری میزان تاثیر پروتکل‌های مختلف تحریک مکرر مغناطیسی مغز #rTMS در درمان #افسردگی:
🔹اگرچه پروتکل‌های مختلفی برای درمان افسردگی مورد مطالعه قرار گرفته‌اند اما میزان تفاوت اثرپذیری و مقبولیت آنها مشخص نشده است. 81 کارآزمایی بالینی (4233 بیمار) با بیش از ده جلسه درمانی از PubMed/MEDLINE, EMBASE, PsycInfo و Web of Science که تا 1 اکتبر 2016 به چاپ رسیده بودند مورد بررسی قرار گرفت. این مرور توسط دو شخص مستقل که از فرم‌های استاندارد برای استخراج اطلاعات و ارزیابی کیفیت استفاده می‌کردند انجام گرفت. تفاوت‌های بالینی ناچیزی در بین پروتکل‌های رایج وجود داشت.

این مقاله در مجله JAMA Psychiatry با ضریب تاثیر 14.4 به چاپ رسیده است.

✅ Repetitive Transcranial Magnetic Stimulation for the Acute Treatment of Major Depressive Episodes: A Systematic Review With Network Meta-analysis

Main Outcomes and Measures:
Response rates and acceptability (dropout rate). Remission was the secondary outcome. Effect sizes were reported as odds ratios (ORs) with 95% CIs.

Results
The interventions more effective than sham were ✅ priming low-frequency (OR, 4.66; 95% CI, 1.70-12.77), ✅ bilateral (OR, 3.96; 95% CI, 2.37-6.60), ✅ high-frequency (OR, 3.07; 95% CI, 2.24-4.21), ✅ θ-burst stimulation (OR, 2.54; 95% CI, 1.07-6.05), ✅ low-frequency (OR, 2.37; 95% CI, 1.52-3.68)
Novel rTMS interventions (accelerated, synchronized, and deep rTMS) were not more effective than sham.
The estimated relative ranking of treatments suggested that priming low-frequency and bilateral rTMS might be the most efficacious and acceptable interventions among all rTMS strategies. However, results were imprecise and relatively few trials were available for interventions other than low-frequency, high-frequency, and bilateral rTMS.
