Continuing EEG Experiment

During the last part of first semester of the EEG Project, our team decided to rework a lab and create our own lab. We wanted to find a way to analyze intelligence, and look for any patterns in the brain waves. But how can we measure intelligence?

Our team decided to use Howard Gardner's Theory of Multiple Intelligence. Using the website Identifor.com. we selected 8 games (each measuring a specific intelligence category) and have each test subject play each game while we record their EEG's.

While we set up our new OpenBCI equipment (and wait for all the parts of our new headgear to finish printing in the 3D printer), we decided to continue this project.

2016 Summer STEM Interns!

So excited to be a part of the 2016 Summer EEG Stem Internship!

Our team has relocated to room SA-118 for the summer, Mondays thru Thursdays from 10am-2pm. Come check us out!
Our main goal this summer is to transition our software from BioPac to OpenBCI. This new software will allow us to obtain a greater range of brain waves while creating labs with custom perimeters.

Reaction Time 1

Experimental Objectives:

1. Observe the effect of learning and the effect of anticipating the stimulus delivery on reaction time.
2. Compare reaction times in four stimulus-response situations:
1. Fixed interval stimulus presentation using the dominant hand for the response.
2. Random interval stimulus presentation using the dominant hand for the response.
3. Fixed interval stimulus presentation using the nondominant hand for the response.
4. Random interval stimulus presentation using the nondominant hand for the response.
3. Compare the reaction times for groups of subjects by calculating the statistics of group mean, variance, and standard deviation in each of the four stimulus-response situations.

Electrooculogram (EOG) I
The experimental objective was to record and compare horizontal eye movements during real and simulated tracking of a pendulum. And to record and compare vertical eye movements during real and simulated tracking of a pun in the vertical plane. Finally, the subject's eye movements were recorded during reading three different ways: easy reading silently, challenging reading silently, and challenging reading aloud.

Electrocardiogram and Pulse Experiment

Experiment Objectives 

• To become familiar with the principle of plethysmography and its usefulness in qualitatively assessing peripheral changes in blood volume.

• To observe and record changes in peripheral blood volume and pressure pulse under a variety of both experimental and physiological conditions.

• To determine the approximate speed of the pressure pulse wave traveling between the heart and the finger.

• To illustrate the electrical activity associated with normal cardiac activity and how it relates to the flow of blood throughout the body.

Electrocardiography (ECG) 1

Lab Abstract and Objectives:

Research Director monitors participants as they record ECG

• To become familiar with the electrocardiography as a primary tool for evaluating electrical events within the heart.
• To correlate electrical events as displayed on the ECG with the mechanical events that occur during the cardiac cycle.

• To observe rate and rhythm changes in the ECG associated with body position and breathing.

Lab Abstract and Objectives:

• EEG experiments were performed on live subjects.
• Subjects were seated, relaxed with eyes closed, performing mental arithmetic, hyperventilation, and relaxed with eyes opened.
• Brain waves were analyzed.

Participants proceed with EGG on live subject.
