In-vivo EEG Changes During A Panic Attack in a Patient With Specific Phobia

Figures

Figure 1. A (left) and B: EEG-recordings during panic attack minus pre-panic baseline EEG. The red-blue color scale represents P < 0.01 (red) and P < 0.05 (blue). The “Theta” (4-8 Hz) in image A is a representation of a significant reduction in θ activity (P < 0.01) across the whole surface of the skull. This Figure shows Linked Ears reference.

Figure 2. Result of absolute power percentage difference between pre-panic and panic state of delta, theta and high beta frequencies at central locations, Laplacian montage.

Table

**Table 1.** Results of Paired T-tests, Laplacian Electrode Montage
	Delta	Theta	Alpha	Beta	High Beta
	1.0-4.0 Hz	4.0-8.0 Hz	8.0-12.0 Hz	12.0-25.0 Hz	25.0-30.0 Hz
In this two-tailed test, α < 0.05 percent is considered significant. * values indicate voltage decrements in the frequency band (columns) at a specific area on the skull (rows). ** values indicate increased voltage.
