Brain Waves, Sine Waves and the Fourier Transform - Sapien Labs | Shaping the Future of Mind Health
The most popular method of analyzing brain signals is to decompose it into its component sinusoids using the fourier transform. However a non-sinusoidal physiology poses challenges.
Share Tweet Share Pin Email The most popular method of analyzing brain signals is to decompose it into its component sinusoids using the fourier transform. However a non-sinusoidal physiology poses challenges. The Theory The communication between different groups of neurons needed to coordinate various simulii and translate them into a coherent behavior is thought to be enabled by neuronal oscillations. An oscillation can be defined as cyclical or rhythmic changes in some measure of a signal. When defined in the context of a neural signal like EEG or LFPs, it can be thought of as rhythmic vari
