Transcranial DC Stimulation is very powerful and if applied improperly,
may cause mental impairments and behavioral dysfunction. The tDCS
sessions are to be used only by qualified clinicians who have a thorough
understanding of tDCS and the clinical ability to recognize and treat any
adverse reactions resulting from usage of tDCS. Mind Alive Inc., and its
employees will not be responsible for any undesirable side effects that
may be caused by the use of this device. We recommend that all clients
sign a waiver before use. It is the responsibility of the clinician to
determine proper electrode placement and appropriate and safe current
usage. Mind Alive Inc. does not claim any medical benefits from the use
of tDCS nor claim to have any expertise in the use of tDCS. The use of the
Oasis Pro as a tDCS device is solely the responsibility of the user.

Neuronal excitation of
30 to 40% is achieved by
anodal (+) stimulation,
while inhibition of 20 to
30% is achieved by
cathodal (-) stimulation.
WHAT IS tDCS
When a DC current is applied over the scalp with the intention of
altering neuronal activity, it is known as transcranial DC Stimulation.
tDCS is effective in modulating spontaneous neuronal firing. Applying
tDCS at intensities of 1 milliamp for roughly 20 minutes has been shown
to either excite or inhibit the sensori-motor cortex, with the effects
typically lasting a few hours. However, effects from repeated use may be
permanent.
Anodal stimulation has also been shown to
increase both beta and gamma activity in
the visual cortex, while cathodal stimulation
has decreased beta and gamma activity.
Stimulation is generated by putting a wet
cloth, cotton ball or sponge on the scalp
over the brain regions to be affected and/or
a sponge or cotton ball on the shoulder or the face. The tDCS sessions
deliver a maximum intensity of 2.2 milliamps. To determine electrode
placement and intensity to use, you will need to consult research. See
Dave’s tDCS article at:
https://mindalive.com/tdcs/
The effectiveness and comfort of the Oasis Pro tDCS is based on a
current density of 50 μa/cm2for the small and long thin active
electrodes, and less than 20μa/cm2for the large reference electrode. The
active electrode/sponge contact area is approximately 20 cm2. A
current of 1mA/20 cm2= 50μA/cm2. The reference electrode/sponge
contact area is approximately 60 cm2. A current of 1ma/60 cm2=
17μA/cm2.
Therefore, we recommend using the 1mA session with the electrodes
provided with this kit. Using currents higher than 1mA with the
electrodes provided may cause discomfort with no clinical gains.

tDCS SESSIONS
STARTING A SESSION
The tDCS sessions on the Oasis Pro have their own session
group to distinguish them from CES/MET sessions.
Tap until the tDCS light comes on. Use the INT or to
highlight a tDCS session and press to start the session.
There are six (6) tDCS sessions: 0.25mA, 0.50mA, 0.75mA,
1.00mA, 1.50mA, and 2.00mA. Each of these sessions is 20
minutes long. Additionally, two slots are available to store
custom tDCS sessions ( 1 and 2).
SUGGESTED PLACEMENTS

While the Oasis Pro
is resetting the
and lights may
turn on. This is to
reduce the reset
time. No stimulus is
being generated.
tDCS will only run with a
good connection rating.
If a bad connection is
detected, please adjust the
electrodes, re-wet the
sponges, or add salt to the
water to achieve a better
connection.
USING tDCS
CONNECTION TEST
When a tDCS session first starts, the OASIS Pro checks the electrical
connection by entering test mode just as it does for the CES sessions. The
graph will display one of the following codes to indicate the status of the
connection. The tDCS session will begin automatically only when
a good connection is detected.
Open/Bad
Connection
(blinking)
Good
Connection
(solid)
If an open connection is detected during a
session, the Oasis Pro will pause the output and
wait for the electrodes to be reconnected. The
open connection error (red) will display for a
couple of seconds. The graph may scroll up and
down indicating that the unit is returning the
voltage to a safe testing level; this may take up
to 20 seconds. If a connection is not made within
two (2) minutes, the Oasis Pro will shut off.

Red pin is anodal (+),
which enhances neuronal
activity.
Black pin is cathodal (-),
which inhibits neuronal
activity.
USING tDCS
IMPORTANT
If at any time the client has an adverse reaction, disconnect one or both
electrodes or unplug the cable to pause the session. You may also press
the power button to end the session. Unlike CES, the intensity cannot
be manually adjusted and preferences cannot be set for tDCS sessions.
ELECTRODE PLACEMENT AND SETUP
In order to perform tDCS, you must always connect two electrodes to the
body in order to have a complete circuit. Your tDCS kit includes a high
quality cable with pin connectors. There are also four carbon electrodes:
two small, one large and one long thin. Place a small electrode over the
specific site to be treated. Use long thin electrode for treating two sites
simultaneously such as FP1 and FP2 (for ADHD) or FZ and CZ, then CZ
and PZ (for OCD). Use the large electrode
as the receiver to complete the circuit.
Soak the sponges in tap water or an
appropriate saline solution, and place the
small sponge on the area of the head
being treated. Put the small electrode
inside the sponge pouch. Place the large
electrode inside the large sponge pouch
on the opposite side of the body (eg.
opposite side of the head, face or
opposite shoulder). Use the headband to secure the sponges and
electrodes to the head.
Appropriate saline solutions include contact lens saline solution, or a
mixture of salt and tap water (½tsp / 500ml).

The CD and patch cord
are not included if the
tDCS kit is purchased at
the same time as the
Oasis Pro. The sessions
will be installed at the
factory.

INSTALLING TDCS SESSIONS
The CD containing the tDCS sessions can either
be played on a CD player (as an audio CD) or
read using a computer. When used with a
computer, both DAVID Session Editor files and
audio (.WAV) files are available.
Download the sessions to the Oasis Pro using
the audio files (or a CD player).
•Connect the audio in jack ( ) on the Oasis Pro to the headphone jack of
the CD player or computer.
•Turn the Oasis Pro on. Set the volume to a comfortable listening level
(approx. 15-20% on a computer).
•Play the “Oasis Pro tDCS Session Set.wav” file on the computer (or start
the CD player). After a few seconds the number LEDs will scroll up and
down, and then a tDCS session number will flash. Each of the sessions
will take 8-10 seconds to program.
•Check the Oasis Pro to ensure that all 6 sessions are available in the
tDCS session group.
If the sessions have not downloaded correctly, adjust the volume and try again.
