9 months: Layer 3c and layer 4 cortical neurons are functional {brain development, 9 months}. Sensory tracts between thalamus and primary sensorimotor cortex are ready. Motor tracts between motor cortex and cerebellum are ready. Thalamus and lower gyrus-cinguli layers are in intraorganismic short circuit. Brain-wave waking and sleeping patterns are like adult.
