Unconscious switching of dorsal and medial pathways for plasticity and stability during NREM and REM sleep

The paper shows that during non-REM sleep, plasticity increases in the DLPFC, while during REM sleep, stability increases in the mPFC, both related to E/I balance changes and learning outcomes.

Sleep is associated with reduction of excitatory signaling in medial prefrontal cortex

The paper shows that reduced glutamate levels, an excitatory neurotransmitter, are associated with better sleep onset in humans, while GABA levels remain stable.

First-night effect reduces the beneficial effects of sleep on visual plasticity and modifies the underlying neurochemical processes

The paper shows the first-night effect reduces sleep's benefit on visual plasticity and alters neurochemical processes during sleep.

Visual perceptual learning of a primitive feature in human V1/V2 as a result of unconscious processing, revealed by Decoded fMRI Neurofeedback (DecNef)

This study uses DecNef to show that unconscious exposure-based visual perceptual learning occurs in V1/V2 without conscious perception of motion.
