4 main theories of sleep
|
vascular=some said increase or decrease of blood to brain
neural= retraction/paralysis of neurons or expansion of neuron processes chemical= lack of O2 or accumulation of toxic/fatiguing substances during W *hypnotoxic theory-->sleep factors behavioral= decreased sensory stimulation or cortical inhibition *inhibition theory=something removed or inhibited in brain |
