Developement
Neonatal
trace discontinue :red_flag:
1sec....10sec...1sec...
#
between species
Hum: ...........E.............P0.......
Rat : ..E.......P0.....P.....P12-14
on/off
rather neuromodulation
trace alternant
low amplitude oscillations
patterns :red_flag:
saltatory changes
plateau
days-weeks
no behavioral or state-dependent modulation
ocsillations
SAT (TCA)
#
slow...super slow
DС
over 0.5-1Hz
in humans
don't transform in up states
#
EGO (РГО)
gamma excitation from Thalamus
adult - from perisomatic inhibition
cortico-cortical synchro
thalamo-cortical unit's
developement
intermittent events
spindle bursts

spinal chord--muscles--cortex
in visual cortex
longer
rerely
retinal SA
long events
5-10 sec
when pup grow older
in rats
dissapear
when :eye:
appear early delta (slow) waves
sleep phases emerge
at first in somatosensory
than in visual
delta-brushes
in humans
don't transform to adult
disappearance
days or months
adult
almost all activity in sensory cortex triggered by thalamus
roles
syncro
amplification
not a information processing
need async
gestational age
natural sensory deprivation
Adult :red_flag:
cortical activity
sleep cycles
continuous
interhemispheric syncrony
less lowfrequency activity
amplitude increases and than again decreases
