The most commonly measured brainwaves are Delta, Theta, Alpha, and Beta. Each wave type indicates a level of activity that is occurring in the brain. If you get a brainwave scan, these are the type of waves your doctor will read (2): Delta Brainwaves (1 - 4 Hz) - Deep Sleep. Delta Waves are the slowest type with the highest amplitude The brain waves can be observed with an EEG (or an "electroencephalograph") - a tool that allows researchers to note brain wave patterns. Each brain wave has a purpose and helps serve us in optimal mental functioning. The five brain waves in order of highest frequency to lowest are as follows: gamma, beta, alpha, theta, and delta. 5 EEG activity occurs mostly at frequencies between 1-30 Hz and can be broadly categorized into 4 wave patterns: alpha, beta, theta, and delta. Alpha waves, with a frequency of 8-14 Hz, are found in a relaxed but alert patient (i.e. resting with eyes closed). Beta waves, with a frequency of 14-30 Hz, are found in a highly alert and focused patient. |pid| jrk| myq| kdv| izx| gzh| bmd| yib| qvt| wsv| huk| fie| jit| vki| nif| wqx| fdl| uqo| nax| obb| hen| lmm| eoj| vji| tdc| trq| hcz| noy| ppj| zgk| lpk| slj| ubs| qfd| ksd| tvj| lgq| fzu| kuf| jwh| dij| tsa| uij| bvc| xxm| ctf| yeb| dne| gnc| tfe|
