Nootropics (/ n oʊ. ə ˈ t r oʊ p ɪ k s / noh-ə-TROHP-iks or / n oʊ. ə ˈ t r ɒ p ɪ k s / noh-ə-TROP-iks), [1] colloquially brain supplements, smart drugs and cognitive enhancers, are natural, semisynthetic or synthetic compounds which purportedly improve cognitive functions, such as executive functions, attention or memory.
Choline is an essential nutrient and its primary function within the human body is the synthesis of cellular membranes, [16] although it serves other functions as well. It is a precursor molecule to the neurotransmitter Acetylcholine which serves a wide range of functions including motor control and memory.
Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
The hippocampus regulates memory function. Memory improvement is the act of enhancing one's memory. Factors motivating research on improving memory include conditions such as amnesia, age-related memory loss, people’s desire to enhance their memory, and the search to determine factors that impact memory and cognition.
In general, the more emotionally charged an event or experience is, the better it is remembered; this phenomenon is known as the memory enhancement effect. Patients with amygdala damage, however, do not show a memory enhancement effect. [78] [79] Hebb distinguished between short-term and long-term memory. He postulated that any memory that ...
The brain's neuronal and glial cells require sufficient nutrients for energy to perform important cognitive functions such as attention and memory, [64] [65] and without a steady supply of nutrients including glucose, fatty acids, and vitamins B1 (Thiamine), neural activation required for memory functions becomes impaired.

The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
