2 Cortex in general, network, current model of function

Cerebral cortex

• neuronal cell bodies

• dendrites (un)methylated axons

• axon terminals

• glial cells

• synapses

• capilares

• few cell bodies

• mainly long-range myelinated axon tracks

large furrow dividing the brain into lobes and hemispheres

shallow groove that surrounding a gyrus (ridge)

• motor and non-motor functions

• conscious movement

• emotional expression

• problem solving

• memory

• language

• judgement

• sexual behaviors

• sensory information integration

• spatial orientation

• cognition

• computation

• Visual perception

• Color recognition

• reading

• reading comprehension

• depth perception

• recognition of object movement

• auditory perception

• memory

• speech

• language comprehension (Wernicke’s area)

• emotional responses

• visual perception

• facial recognition

• Visual neurons are orientation-selective

• One neuron would just be active if a horizontal bar is shown, and not if its vertical

In children without emergence delirium, an electroencephalogram pattern of sleep or drowsy states was observed before peaceful awakening. In children with emergence delirium, arousal with clinical delirium occurred before observation of electroencephalogram patterns of sleep.
