Sleep deprivation may additionally affect memory by reducing the proliferation of cells in the hippocampus. [51] Sleep deprivation has also been associated with decreased overall membrane excitability of neurons in the brain. Activation of these membranes is critical for the formation of memories. [52]
The negative effects of sleep deprivation on alertness and cognitive performance suggest decreases in brain activity and function. These changes primarily occur in two regions: the thalamus , a structure involved in alertness and attention, and the prefrontal cortex , a region subserving alertness, attention, and higher-order cognitive ...

Common short-term side effects of sleep deprivation may include: Daytime sleepiness. Lack of alertness. Moodiness and irritability. Fatigue. Impaired memory.
The effects of REM sleep deprivation (RSD) on neurotrophic factors, specifically nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF), were assessed in 2000 by Sie et al.
