tDCS Clinical Trials

I’ve been noticing a growing number of announcements of clinical trials investigating the efficacy of transcranial Direct Current Stimulation (tDCS). Eventually, they were getting hard to ignore. So I got to wondering whether this was just me or whether there was genuinely an identifiable increase. A lot of the trials are announced on clinicaltrials.gov, so […]

The effects of Transcranial Alternating Current Stimulation (tACS) at Individual Alpha Peak Frequency (iAPF) on motor cortex excitability of young and elderly adults

Interesting new paper about tACS and peak alpha : https://www.sciencedirect.com/science/article/pii/S1388245718304000   Transcranial alternating current stimulation (tACS) was shown to modulate brain oscillation, cortical excitability and behaviour. This technique allows for the direct perturbation of brain oscillation such as the EEG alpha wave (8–12 Hz). In aging, there is correlation between the decrease in alpha activity and […]

EEG Primer – Part 4

EEG EQUIPMENT To fully understand what people think, you need to look inside their heads. EEG (electroencephalography) is the tool for doing that job; it gives immediate information into the role of the brain, by detecting the small amounts of electrical activity produced by the brain. EEG has been used by academics and neuro marketers along with […]

EEG Primer – Part 3

Risks The EEG test is completely safe and painless. The patient does not feel any sort of discomfort and there are no risks associated with an EEG. Some EEG’s do not have any stimuli which may be useful in detecting abnormalities. Stimuli like flashing light may be added so that abnormalities become apparent. If the […]

How is the EEG data interpreted? As the electrical activity produced by the brain is examined by the EEG equipment, we can interpret which areas of the brain are processing which information at a specific time. Occipital lobe The occipital lobe makes sense of the visual information in order for us to understand it. It […]

Glossary of Neuroscience Terms

The foc.us “to do” list is very, very long. Some items have been on it for a very, very long time. One task was to create a glossary of neuroscience terms which has now been started.

Sporting excellence is achieved through years of dedicated practice. Whether you’re trying to increase the curve on your free kicks or perfect your golfing swing, you will spend hours repeating the actions over and over again until you can execute them with the precision you need. But we all know that it’s not just your […]

EEG Primer – Part 1

As you think, see, sense, dream, or try to solve a crossword puzzle or start to learn how to drive, the brain is constantly active, engrossing all the information it is presented with, compressing and re-connecting the existing data, and integrating all of it into an experience for you. Everything you see, understand, learn is […]

A quick biofeedback primer

NEUROFEEDBACK Neuro-feedback is a way to train brain activity. It is a non-invasive method of direct brain function training. It is helpful for people that have brain imbalances. Basically it is a kind of biofeedback, which teaches self-control of brain functions to subjects by measuring brain waves and providing a feedback signal. Brain waves tells […]
