If using your own electrodes it is not
recommended to create novel electrode
placements.

Do not position the electrodes so that the
current may pass through the brainstem.

grazes or damaged skin.

Allow at least 48 hours between usage.

Always use the electrodes with wet
sponges.

Do not touch the metal electrodes as this
can lead to burns.

What you need to understand before
using foc.us

foc.us is designed to improve your mental
gaming skills.
You are exciting and inhibiting sections
of your pre-frontal cortex with an electric
current.
Possible side effects include tingling
sensations under the electrodes or on the
scalp, visual artifacts, nausea, headaches
and fatigue.
If you experience any of these you should
stop using foc.us.
Repeated use may lead to skin irritation.
If you exceed the recommended durations

you increase the risk of consolidating both
the excitatory and inhibitory processes.
You may feel a tingling sensation, or a hot
or cold sensation.
If this is uncomfortable or painful then
you should stop session and remove the
electrodes.
Redness may appear under electrodes
after use which will disappear after a short
time.
Foc.us should not be used during any
activities other than seditary gaming.
If you see white flashes, or phosphenes you
should adjust the position of the headset
on your head, pushing it further back away
from your eyes.
