brain rhythyms

what are the different eletrical rhythyms of cerebral cortex

sleeping, walking, hibernation, breathing, walking, electrical rhythms of cerebral cortex.

what is EEG

classical method of recording brain rhythms essential for studing sleep

what is circadian rhythms?

changes in physiological functions according to brain clock

how are brain waves recorded

noninvasive, painless

electrodes placed on scalp

connected to amplifiers and recording devices

voltage functuations of tens of microvolts

electrode pairs: measure different brain regions

what are categories of EEG rhythyms catgeorizd by

their frequency

what frequency is Beta rhythms

15-30 Hz activated cortex, attentive cortex

what is the frequency of alpha rhythms

Alpha 8-13 Hz quiet waking state

what is theta rhythms

4-7 HZ, some sleep and waking states

what is delta rhthyms

less than 4Hz deep sleep

what is characteristic of deep sleep

high synchrony, high EEG amplitude

what is epilepsy

repeated sezuires

what are some of the causes of epilepsy

tumor, trauma, genetics, infection, vascular disease, many unknown

what is a generalized sezuire

sezuire of the entire cerebral cortex

complete behavuor distuption, consciences loss

partial seizure

circumscibed cortex region, abnormial sensation or aura

absence seizure

less than 30 seconds of generalizez 3 Hz EEG waves

what is dravet syndrome

severe seizures as an infant, caused by inhibition imbalance

what does THC do to cb1

activates cb1

what is thc derived from?

what does CBD come from

CBDA

CBG inactivated cb1

what does CBD do

dampen cb1 activity, derived from cbda
